C language - Adding 2 numbers

Hey :)

What is a variable ?

let's suppose you want to add 2 numbers, each number, each value needs a space in the memory, you need to store this 2 numbers in "variables", because of that, you need to declare at the beginning of your program.

let's look at our code:

# include < stdio.h >

# include < stdlib.h >

int main()
{
int num1, num2, result; //Let's declare 3 variables

printf("Type the first number "); //Write this message
scanf("%d", &num1); //Read the value, "%d" means is a integer

printf("Type the first number "); //Write this message
scanf("%d", &num2); //Read the value, "%d" means is a integer

result = num1 + num2; //Result = num1 plus num2

printf("%d + %d eh %d", num1, num2, result); //Write the value of these variables

printf("\n\n");
system("pause");
}
