c++ sizeof code example

Example 1: sizeof operator in c++

cout << "char: " << sizeof(char) << endl;
cout << "int: " << sizeof(int) << endl;
cout << "float: " << sizeof(float) << endl;
cout << "double: " << sizeof(double) << endl;

Example 2: c++ size_t

// size_t is a type definition for unsigned long long
// This means that writing size_t is the excact same as
// writing unsigned long long
