/*Exercise 3 - Repetition

Write a C program to calculate the sum of the numbers from 1 to n.
Where n is a keyboard input.

e.g.

n -> 100
sum = 1+2+3+....+ 99+100 = 5050

n -> 1-
sum = 1+2+3+...+10 = 55 */

#include <stdio.h>
int main() {

  int number;
  int sum = 0;

  printf("Enter the number: ");
  scanf("%d", &number);

  for (int i = 1; i <= number; ++i) {
    sum = sum + i;
  }

  printf("The sum of the number is: %d", sum);
  return 0;
}
