2.5.3.Sum the integers from 1 to a user-specified number

#include <stdio.h>



int main(void)

{

  long sum = 0L;

  int count = 100;



  for(int i = 1 ; i <= count ; i++){

    sum += i;

  }  



  printf("\nTotal of the first %d numbers is %ld\n", count, sum);

  return 0;

}

Total of the first 100 numbers is 5050

2.5.int Calculation
	2.5.1.	Simple calculations
	2.5.2.	Divide Integer
	2.5.3.	Sum the integers from 1 to a user-specified number
	2.5.4.	If both operands i1 and i2 are integers, the expression i1/i2 provides integer division
