C Programming Tutorial Part 3 – Variables Basics | Linux.com


Up until now, we’ve discussed the basics of what a C program is, how to compile and execute it, and what are preprocessors. If you have gone through these tutorials, it’s time we discuss the next topic, which is variables. 

Variables are one of the core elements of C programming as they store values for programmers to use as per their requirement. Let’s understand their basics through an example. Following is a basic C program:

#include <stdio.h>

int main (void)
{
 int a = 10;
 char b = 'z';
 float c = 1.5;
 printf("n a=%d, b=%c, c=%f n", a,b,c);
 return 0;
}

In previous C programming tutorials, we have already explained things like what is ‘stdio.h,’ what does ‘#include’ mean, and what is a function (especially ‘main’). So, we’ll directly jump onto the variables part.
