Example 1: c program to add two numbers

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

    int number1, number2, sum;
    
    printf("Enter two integers: ");
    scanf("%d %d", &number1, &number2);

    // calculating sum
    sum = number1 + number2;      
    
    printf("%d + %d = %d", number1, number2, sum);
    return 0;
}

Example 2: add 2 numbers in c

printf("Sum : %d", sum);
return(0);

Example 3: addition of two numbers in c

int num1,num2;
printf("%d",num1+num2);

Example 4: addition in c

/*Program for adding two numbers*/
#include <stdio.h>
int main(){
	int a, b, sum; //declare the variables that will be used, a will store the first number, b second number and sum, the sum.
    printf("Enter the first number: \n"); //Prompts user to enter the first number.
    scanf("%d", &a);//Accepts input and saves it to variable a
    printf("Enter the second number: \n");
    scanf("%d", &b);
    sum = a + b; //Formular to add the two numbers.
    printf("Sum is %d", sum);
}
