Write a function that receives two numbers, m and n and calculates and displays the sum of the integers from m to n. For example, if the arguments are m = 3 and n = 7, the function should calculate 3 + 4 + 5 + 6 + 7

The program to this question as follows:

Program:

//header file

#include <stdio.h> //defining header file

void inc(int m,int n) //defining method inc

{

   int sum, i; //declaring variable

   sum=m; //holding value of m variable

   for(i=++m;i<=n;i++) //loop for calculate number between given range  

   {

   sum=sum+i; //adding value

   }

   printf("sum of the integer is : %d",sum);//print value

}

int main() //defining method

{

   int m,n; //defining integer variable

   printf("Enter m value: "); //message

   scanf("%d",&m); //input value by user in variable

   printf("Enter n value: "); //message

   scanf("%d",&n);//input value by user in variable

   inc(m,n); //calling method

   return 0;

}

Output:

Enter m value: 3

Enter n value: 7

sum of the integer is :25

Explanation:

In the above code, an "inc" function is declared, that accepts integer parameters that are "m and n", inside the method two integer variable "sum and i" is declared, which is used in the loop.

i need a picture to answer this.
