Addition of two numbers in C programming

Hi, I'm Golam Rabbani.
Today, I will discuss about C programming.
Let's Go.
My Question: How do you write the sum of two numbers in C programming?

Solution:

#include <stdio.h>
int main(){
    int x,y,sum;
    printf("Enter 1st number\n");
    scanf("%d", &x);
    printf("Enter 1st number\n");
    scanf("%d", &y);
    sum=x+y;
    printf("Result: %d\n", sum);
    return 0;
}

Input:

x=10;

y=20;

Output:

Result: 30

Thank you.
