Q: if a five digit number is input through the keyboard write a program to reverse the number.

By -

# include <stdio.h>
int main()
{
    int n,rem,rev;
   
    printf("enter any number : ");
    scanf("%d",&n);
   
    while(n!=0)              /*condition used until n becomes zero*/
   
    {
        rem= n%10;           /*to find the last digit of no*/
        n=n/10;                   /*as n is int so n/10 also be int*/
        rev=rev*10+rem;    /*to find the reverse of the no entered*/
    }
   
    printf("reverse of no is %d",rev);
   
    return 0;
}
-----------------------------------------
output:

enter any number : 12345
reverse of no is 54321

Q: The length & breadth of a rectangle and radius of a circle are input through the keyboard. Write a program to calculate area & perimeter of the rectangle and area & circumference of the circle.

By -
#include<stdio.h> int main() {     float l, b, r,ac, cc, ar, pr;  /*l is length,b is breadth,r is radius*/     /*For rectangle*/     printf("Enter the length of rectangle: ");     scanf("%f",&l);       printf("Enter the breadth of rectangle: ");     scanf("%f", &b);     /*For circle*/     printf("\nEnter the radius of circle: ");     scanf("%f", &r);     /*Calculate area & perimeter of the rectangle*/       ar = l * b;    /*ar is Area of Rectangle = Length x Breadth*/       pr = 2 * (l + b);    /*pr is Perimeter of Rectangle = 2 x (L + B) or addition of all sides*/      /*Calculate area & circumference of the circle*/       ac = 3.14 * r * r;   /*ac is Area of Circle = 2 x Pi x r^2 where Pi = 3.14*/       cc = 2 * 3....

Q: If a five-digit number is input through the keyboard, write a program to calculate the sum of its digits. (Hint: Use the modulus operator ‘%’)

By -
#include <stdio.h> int main() {         int num, sum;         printf("enter any number : ");     scanf("%d",&num);         while(num != 0)    /*condition used unti num becomes zero*/     {         /* modulo operator is used to find remainder*/         sum += num%10;   /* sum is increase with new remainder after the no is divide by 10 */         num  =  num/10;     }     printf("sum of digits of given no is %d",sum);     return 0; } ----------------------------------------- output : enter any number : 12345 sum of digits of given no is 15
