This version utilizesstd::stringclass methods to do the conversion, making it a far safer version than dealing withsprintfas shown in the previous example. #include<iostream>intmain(){intnumber=1234;std::string tmp=std::to_string(number);charconst*num_char=tmp.c_str();printf("num_char: ...
Now that we have the basic concept let’s see how we can use macros for converting a float to a string. #defineSTRINGIFY(x) #xintmain(){constchar*str=STRINGIFY("Hello, World !");// str now contains "Hello, World!"return0;} ...
