Question

Write a c program to compute the the average of every third integer lying between 1 to 100 using while loop

Answer 1

Program :


#include<stdio.h>

#include<conio.h>

void main()

{

     int a,b,c;


     clrscr();

     for(a=1,b=0,c=0;a<=100;a+=3)

     {

          c+=a;

          b++;

     }

     printf("\n\tAverage of every third integer between 1 to 100 is %d",c/b);

     getch();

}


Documentation :

Variable a is used for count 1 to 100variable c is sum of every third integer . get by a because a is incremented by 3 in each loop turn.Variable b is used to trace how many third number are in range of 1 to 100.As we know formula of calculating average is sum of value divided by number of element is perform while printing

Answer 2

Answer:

#include <stdio.h>

int main()

{

int i = 0;

static int sum = 0;

int j, x, k, avg;

while(i<=100){

 i++;

 j++;

 if(j == 3){

  printf("%d ", i);

  j = 0;

  sum += i;

  k++;

 }

}

 

printf("\nSum = %d", sum);

printf("\nNumber = %d", k);

printf("\nAverage = %d", sum/k);

scanf("%d", &x);

return 0;

}
