Question

I the below mentioned program:

string s;
cout<<"Enter a string:";
gets(s);

I expect my input to be of the form: “Hilton Hotels”.

On using gets, I get the following error:

 error: cannot convert ‘std::string {aka std::basic_string<char>}’ to ‘char*’ for argument ‘1’ to ‘char* gets(char*)’

I can not use “cin” as I want my input to consist of space and special characters like ‘_’ etc, also I want my delimiter to be ‘enter’. Is there some other way…or please be kind enough in correcting the error.

Answer 1

gets isn’t very c++ (it’s for compatibility with C). Use this:

#include <iostream>
#include <string>

int main()
{
    std::getline(std::cin, s);
    std::cout << s << '\n';
}

Also, look at std::ios::skipws and <iomanip> for whitespace handling options
