Answer:

In Python:

Length = float(input("Length: "))

Width = float(input("Width: "))

Area = Length * Width

Perimeter = 2*(Length + Width)

print(Area)

print(Perimeter)

Explanation:

This gets the length from the user

Length = float(input("Length: "))

This gets the width from the user

Width = float(input("Width: "))

This calculates the area

Area = Length * Width

This calculates the perimeter

Perimeter = 2*(Length + Width)

This prints the area

print(Area)

This prints the perimeter

The kernel module that creates a proc file named /proc/seconds that reports the number of elapsed seconds since the kernel module was loaded is in the explanation part.

Kernel modules are chunks of code that can be loaded and unloaded from the kernel as needed. They enhance the functionality of the kernel without requiring a system reboot. A module can be set to be built-in or loadable.

Here is an example kernel module that creates a proc file named /proc/seconds that reports the number of elapsed seconds since the kernel module was loaded:

#include <linux/module.h>

#include <linux/kernel.h>

#include <linux/proc_fs.h>

#include <linux/jiffies.h>

#include <asm/uaccess.h>

#define PROC_NAME "seconds"

static struct proc_dir_entry *proc_entry;

static unsigned long start_time;

static int proc_read(char *page, char **start, off_t off,

                    int count, int *eof, void *data)

{

   int len;

   unsigned long elapsed_seconds = (jiffies - start_time) / HZ;

   if (off > 0) {

       *eof = 1;

       return 0;

   }

   len = sprintf(page, "%lu\n", elapsed_seconds);

   return len;

}

static int __init seconds_init(void)

{

   proc_entry = create_proc_entry(PROC_NAME, 0, NULL);

   if (proc_entry == NULL) {

       printk(KERN_INFO "Failed to create proc entry\n");

       return -ENOMEM;

   }

   start_time = jiffies;

   proc_entry->read_proc = proc_read;

   proc_entry->mode = S_IFREG | S_IRUGO;

   proc_entry->uid = 0;

   proc_entry->gid = 0;

   proc_entry->size = 0;

   printk(KERN_INFO "/proc/%s created\n", PROC_NAME);

   return 0;

The value of ch will be the character entered by the user after executing the code.

The code snippet cin >> ch >> ch >> ch >> ch; reads four characters from the user's input and assigns them to the variable ch. Since the user input is "Try to be a rainbow in someone's cloud." and the code reads four characters, the value of ch after the code executes will depend on the specific characters entered by the user.

In conclusion, without knowing the input, it is not possible to determine the exact value of ch. Therefore, the value of ch will be the character entered by the user after executing the code.

Answer:

#include <stdio.h>

int main(void) {

 int num1;

 int num2;

 int num3;

 printf("Enter three integers: ");

 scanf("%d", &num1);

 scanf("%d", &num2);

 scanf("%d", &num3);

 if (num1 == 0 || num2 == 0 || num3 == 0)

 {

   printf("please input a number greater than zero :)\n");

 }

 if (num1 <= num2 && num1 <= num3)

 {

   printf("%i is the smallest number!\n", num1);

 }

 else if (num2 <= num1 && num2 <= num3)

 {

   printf("%i is the smallest number!\n", num2);

 }

 else

 {

   printf("%i is the smallest number!\n", num3);

 }

 return 0;

}

Explanation:

Alright so let's start with the requirements of the question:

So we needed to create 3 variables to hold each integer that was going to be passed into our script.

By using scanf("%i", &variableName) we were able to take in user input and  store it inside of num1, num2, and num3.

Since you mentioned you were new to the C programming language, I threw in the first if statement as an example of how they can be used, use it as a guide for future reference, sometimes it's better to understand your code visually.

Basically what this if statement does is, it checks to see if any of the integers that came in from user input was the number zero, it told the user it does not accept that number, please input a number greater than zero.

if (num1 == 0 || num2 == 0 || num3 == 0)

 {

   printf("please input a number greater than zero :)\n");

 }

I used this methodology and implemented the heart of the question,

whichever number is smaller, print it out on the shell (output).

if (num1 <= num2 && num1 <= num3)

^^ here we're checking if the first variable we created is smaller than the second variable and the third ^^

 {

   printf("%i is the smallest number!\n", num1);

   ^^ if it is smaller, then print integer and then print a new line so the next line looks neat ^^

   ( incase if your wondering what "\n" is, its a special character that allows you so print a new line on the terminal, kind of like hitting the return or enter key )

 }

else if (num2 <= num1 && num2 <= num3)

^^ else if is used when your checking for more than one thing, and so for the second variable we checked to see if it was smaller than the first and third variable we created ^^

 {

   printf("%i is the smallest number!\n", num2); < -- and we print if it's smaller

 }

Last but not least:

else

^^ if it isn't num1 or num2, then it must be num3 ^^

 {

   printf("%i is the smallest number!\n", num3);

  we checked the first two options, if its neither of those then we have only one variable left, and thats num3.

 }

I hope that helps !!

Answer:

x1 = 39

x2 = 400

x3 = 92

x4 = 62

x5 = 0

Explanation:

This statement calls the f() function passing 2 to the function. The f(x) function takes a number x as parameter and returns the following:

g(x) + math.sqrt(h(x))

This again calls function g() and h()  

The above statement calls g() passing x i.e. 2 to the function g(x) and calls function h() passing x i.e. 2 to h() and the result is computed by adding the value returned by g() to the square root of the value returned by the h() method.

The g(x) function takes a number x as parameter and returns the following:

return 4*h(x)

The above statement calls function h() by passing value 2 to h() and the result is computed by multiplying 4 with the value returned by h().

The h(x) function takes a number x as parameter and returns the following:

return x*x + k(x)-1

The above statement calls function k() by passing value 2 to k() and the result is computed by subtracting 1 from the value returned by k() and adding the result of x*x (2*2) to this.

The k(x) function takes a number x as parameter and returns the following:

return 2 * (x + 1)

As the value of x=2 So

2*(2+1) = 2*(3) = 6

So the value returned by k(x) is 6

Now lets go back to the function h(x)

return x*x + k(x)-1

x = 2

k(x) = 6

So

x*x + k(x)-1 = 2*2 + (6-1) = 4 + 5 = 9

Now lets go back to the function g(x)

return 4*h(x)

As x = 2

h(x) = 9

So

4*h(x)  = 4*9 = 36

Now lets go back to function f(x)

return g(x) + math.sqrt(h(x))

As x=2

g(x) = 36

h(x) = 9

g(x) + math.sqrt(h(x))  = 36 + math.sqrt(9)

                                  = 36 + 3 = 39

Hence

The above statement means that first the function g() calls function h() and function h() is passed a value i.e 2.

As x=2

The function k() returns:

2 * (x + 1)   = 2 * (2 + 1) = 6

The function h() returns:

x*x + k(x)-1 = 2*2 + (6-1) = 4 + 5 = 9

Now The function g() returns:

4 * h(x)  = 4 * h(9)

This method again calls h() and function h() calls k(). The function k() returns:

2 * (x + 1)   = 2 * (9 + 1) = 20

Now The function h() returns:

x*x + k(x)-1 = 9*9 + (20-1) = 81 + 19 = 100

h(9) = 100

Now The function g() returns:

4 * h(x)  = 4 * h(9) = 4 * 100 = 400

Hence

g() returns:

return 4 h(x)

h() returns:

return x*x + k(x)-1

k(2) returns:

return 2 (x + 1)

          = 2 ( 3 ) = 6

Now going back to h(2)

x * x + k(x)-1  = 2*2 + 6 - 1 = 9

Now going back to g(2)

4 h(x)  = 4 * 9 = 36

So k(g(2) + h(2)) becomes:

   k(9 + 36 )

    k(45)

Now going to k():

return 2 (x + 1)

2 (x + 1)   = 2(45 + 1)

             = 2(46)

             = 92

So k(g(2) + h(2)) = 92

Hence

Compute f(0)

f() returns:

return g(0) + math.sqrt(h(0))

f() calls g() and h()

g() returns:

return 4 * h(0)

g() calls h()

h() returns

return 0*0 + k(0)-1

h() calls k()

k() returns:

return 2 * (0 + 1)

2 * (0 + 1)  = 2

Going back to caller function h()

Compute h(0)

0*0 + k(0)-1  = 2 - 1 = 1

Going back to caller function g()

Compute g(0)

4 * h(0)  = 4 * 1 = 4

Going back to caller function f()

compute f(0)

g(0) + math.sqrt(h(0))  = 4 + 1 = 5

f(0) = 5

return g(1) + math.sqrt(h(1))

f() calls g() and h()

g() returns:

return 4 * h(1)

g() calls h()

h() returns

return 1*1 + k(1)-1

h() calls k()

k() returns:

return 2 * (1 + 1)

2 * (1 + 1)  = 4

Going back to caller function h()

Compute h(0)

1*1 + k(1)-1  = 1 + 4 - 1 = 4

Going back to caller function g()

Compute g(1)

4 * h(1)  = 4 * 4 = 16

Going back to caller function f()

compute f(1)

g(1) + math.sqrt(h(1))  = 16 + 2 = 18

f(1) = 18

Compute f(2)

f() returns:

return g(2) + math.sqrt(h(2))

f() calls g() and h()

g() returns:

return 4 * h(2)

g() calls h()

h() returns

return 1*1 + k(2)-1

h() calls k()

k() returns:

return 2 * (2+1)

2 * (3)  = 6

Going back to caller function h()

Compute h(2)

2*2 + k(2)-1  = 4 + 6 - 1 = 9

Going back to caller function g()

Compute g(2)

4 * h(2)  = 4 * 9 = 36

Going back to caller function f()

compute f(2)

g(2) + math.sqrt(h(2))  = 36 +3 = 39

f(1) = 13.7

Now

x4 = f(0) + f(l) + f(2)

    = 5 + 18 + 39

    = 62

Hence  

Compute f(-1)

f() returns:

return g(-1) + math.sqrt(h(-1))

f() calls g() and h()

g() returns:

return 4 * h(-1)

g() calls h()

h() calls k()

k() returns:

2 * (0)  = 0

Going back to caller function h()

Compute h(-1)

-1*-1 + k(-1)-1  = 1 + 0 - 1 = 0

Going back to caller function g()

Compute g(-1)

4 * h(-1)  = 4 * 0 = 0

Going back to caller function f()

compute f(-1)

g(-1) + math.sqrt(h(-1))  = 0

f(-1) = 0

Compute g(-1)

g() returns:

return 4 * h(-1)

g() calls h()

h() returns

h(-1) = 0

Compute k(-1)

k() returns:

return 2 (x + 1)

k(-1) = 2 ( -1 + 1 ) = 2 ( 0 ) = 0

k(-1) = 0

x5 = f(-1) + g(-1) + h(-1) + k(-1)

    = 0  + 0 + 0 + 0

    = 0

Hence
