Chapter No.12: Loop Constructs

Exercise Programs

Q.9: Write a program that inputs a number and displays the message “Prime number” if it is a prime number, otherwise displays “Not a prime number”.

Answer:                                                 

To display the message “Prime number” if it is a prime number, otherwise displays “Not a prime number”, follow the code below:

#include<stdio.h>

#include<conio.h>

void main(void)

{

int n,i;

printf("Enter any number:");

scanf("%d",&n);

for(i=2;i<n;i++)

{

if(n%i==0)

{

printf("\n\t Not a prime number!");

goto lab;

}

}

printf("\n\t Prime number!");

lab:

printf("\n");

}

 

Q.10: Write a program that displays the first 15 even numbers.

Answer:

To display the first 15 even numbers, follow the code below:

#include<stdio.h>

#include<conio.h>

void main(void)

{

int i=2;

printf("First 15 Even Numbers:");

while(i<=30)

{

printf("\n%d",i);

i=i+2;

}

}

 

Q.11: Write a program that inputs a number, and displays its table according to the following format:

Suppose the number entered is 5, the output will be as follows:

5 * 1 = 5

5 * 2 = 10

5 * 3 = 15

.

.

.

5 * 10 = 50

Answer:

To display a table for the above mentioned format, follow the code below:

#include<stdio.h>

#include<conio.h>

void main(void)

{

int n,i;

printf("Enter any number:");

scanf("%d",&n);

for(i=1;i<=10;i++)

{

printf("%d*%d=%d\n",n,i,n*i);

}

}

 

Q.12: Write a program using do-while loop that repeatedly prompts for and takes input until a value in the range 0 through 15 inclusive is input. The program should add all the values before exiting the loop and displays their sum at the end:

Answer:

To fulfill the requirements mentioned on the above statement, follow the code below:

#include<stdio.h>

#include<conio.h>

void main(void)

{

int n,sum=0;

do

{

printf("Enter any number:");

scanf("%d",&n);

sum=sum+n;

}while(n>=0 && n<=15);

sum=sum-n;

printf("\n\t Sum of all values:%d \n",sum);

}

 

Q.13: Write a program that produces the following output:

0

0              1

0              1              2

0              1              2              3

0              1              2              3              4

0              1              2              3              4              5

Answer:

To produce the above mentioned output, follow the code below:

#include<stdio.h>

#include<conio.h>

void main(void)

{

int i,j;

for(i=0;i<=5;i++)

{

j=0;

while(j<=i)

{

printf("%d\t",j);

j++;

}

printf("\n");

}

}

 

Q.14: Write a program the produces the following output:

0              1

1              2

2              4

3              8

4              16

5              32

6              64

Answer:

To produce the output mentioned above, follow the program below:

#include<stdio.h>

#include<conio.h>

void main(void)

{

int i,j=1;

for(i=0;i<=6;i++)

{

printf("%d\t%d\n",i,j);

j=j*2;

}

}
