/**
 * @brief Main function
 * @details
 * This function is used to test `min_printf` function.
 * The numbers and string used for the test is generated randomly (The user can also specify their own value for tests)
 * First integers were tested then floats and at last strings
 * After running the program the user will see three pair of lines with each pair followed by an empty line
 * In each pair of lines, the first line will be printed by `min_printf` function and next line by the actual `printf` function
 * In each line user will see number or string covered with two colons, they are used to check from where the printing was started and where it ends
 * @returns 0 on exit
