Question

Write a program that computes the following summation using a function. a + (a + 1) + . . . + b = i Implement the following function in your program int computesum (int a, int b) This function computesum computes the sum of all the integers from a to b. You can compute the sum i and i and use these to test your program. If your program is correct you should have i + i = i Sample execution of the program is given below Enter a and b 5 10 Sum from 5 to 10 is 45 Sum from 1 to 4 is 10 Sum from 1 to 10 is 55

Explanation / Answer

#include<stdio.h>

int computesum(int a,int b)
{
   int sum=0;
   while(a<=b)
   {
       sum=sum+a;
   a++;
   }
   return(sum);
}

int main()
{
   int arr[100000],a,b,k ;
   printf("Enter the a and b ");
   scanf("%d %d",&a,&b);
k=   computesum(a,b);
  
   printf(" Sum from %d to %d is %d",a,b,k);
   return(0);
}
