Part 15 - Float Primitive Datatype

Today we are going to talk about the C++ float datatype that stores floating point values.

#include <iostream>

int main()
{
    float my_float = 10.1;

    std::cout << my_float << std::endl;

    return 0;
}

Very simply we create a float and assign a simple value to it and print it.

Let's compile and link.

g++ -o 0x05_float_primitive_datatype 0x05_float_primitive_datatype.cpp

Let's run.

./0x05_float_primitive_datatype

We simply see the following.

10.1

It successfully echoed 10.1 to the terminal stdout. Very simple.

Next week we will debug this very simple example.
