Q: Paper of size A0 has dimensions 1189 mm x 841 mm. Each subsequent size A(n) is defined as A(n-1) cut in half parallel to its shorter sides. Write a program to calculate and print paper sizes A0, A1, A2, ….. A8.

By -
#include<stdio.h>
int main()
{
    int i, w=841, h=1189, k;
     for(i=0; i<9; i++)
     {
         printf("\n A%d: %d x %d", i, w, h);
         k = h;
         h = w;
         w = k/2;
     }
     return 0;
}

-----------------------------------------
Output:

 A0: 841 x 1189
 A1: 594 x 841
 A2: 420 x 594
 A3: 297 x 420
 A4: 210 x 297
 A5: 148 x 210
 A6: 105 x 148
 A7: 74 x 105
 A8: 52 x 74

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
