Part 9 - Character Primitive Datatype

Today we are going to talk about the first of the C++ primitive. The char dataype is used to store a single character and must be surrounded by single quotes.

Let's look at our basic example.

#include <iostream>

int main()
{
    char my_char = 'c';

    std::cout << my_char << std::endl;

    return 0;
}

Extremely simple. We are simply creating a char variable called my_char _and assigning it the character _c.

We then print it to stdout and nothing more.

Let's compile and link.

g++ -o 0x03_asm64_char_primitive_datatype 0x03_asm64_char_primitive_datatype.cpp

Let's run.

./0x03_asm64_char_primitive_datatype

Very simply we see the following.

c

It successfully echoed c to the terminal stdout. Very simple.

Next week we will debug this very simple example.
