Question

Write a C program which adds up all the numbers between 1 and 50. Use any type of loop

Answer 1

I am providing the code for sum of digits from 1 to 50 including both. In case you need the code for sum of digit from 1 to 50 excluding 1 and 50 ( 2 to 49 ), then change the for loop condition (line number 7) from 'for (int i = 1; i <= 50; i++)' to 'for (int i = 2; i < 50; i++)'.

Steps:

1. Declare and initialize the variable 'sum' as 0.
2. Use a for loop with iterator variable from 1 to 50.
3. At each iteration of the loop add sum with the iterator.
4. Print variable sum.

Code To Copy:

#include <stdio.h>

int main()

{

    // declare and initialize sum variable as 0

    int sum = 0;

    // start a for loop with iterator variable ranging from 1 to 50

    for (int i = 1; i <= 50; i++)

    {

        // each iteration increment sum with i

        sum = sum + i;

    }

    // print sum

    printf("Sum of numbers between 1 and 50: %d", sum);

    return 0;
