How to print variables in C?

For this explanation we will need a little program

#include <stdio.h>

int main(){

int a=5;

int b=9;

int sum=a+b;

printf("La suma es : %d \n", sum);

}

We can see that as we have said before, we started the code and opened the main.

Inside we declare three variables: a,b and sum;

The numbers inside a and b will be summed and stored in sum.

Now, for printing we put the printf();

Inside we open start and statement: “La suma es : %d \n”

The text will print as it is written, the term %d refers to a variable, finally de \n indicates to the computer to go to the next line.

After this statement there is a comma and the variable that will be printed.

Note: All the variables are represented with the statement: %d. If you want to call several variables in a statement, you just have to write several times “%d”. The variables assigned to the statement %d will depend on the order in which you call them after the comma.

For example:

int A=1;

int B=2;

int C=3;

print(“Esta es una prueba, variable A: %d, variable B: %d, variable C: %d”,A,B,C);

The printed statement will be:

Esta es una prueba, variable A:1, variable B:2, variable C:3
