Note that this method defines theCHAR_LENGTHvariable for better readability. We can pass the integer literal directly to the constructor. #include<iostream>#include<string>using std::cin;using std::cout;using std::endl;using std::string;constexprintCHAR_LENGTH=1;intmain(){charcharacter='D';...

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;} ...

std::atoi: Function for converting a C-style string to an integer. str: The input C-style string to be converted. Code: #include<iostream>intmain(){constcharcharArray[]="23323experimental_string";intintValue=std::atoi(charArray);std::cout<<"Converted Integer: "<<intValue<<std::endl;...
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: ...
