How to print a string in C++ [closed]

You need to access the underlying buffer:

printf("%s\n", someString.c_str()); 

Or better use cout << someString << endl; (you need to #include <iostream> to use cout)

Additionally you might want to import the std namespace using using namespace std; or prefix both string and cout with std::.

You need #include<string> to use string AND #include<iostream> to use cin and cout. (I didn't get it when I read the answers). Here's some code which works:

#include<string> #include<iostream> using namespace std; int main() { string name; cin >> name; string message("hi"); cout << name << message; return 0; } 

You can't call "printf" with a std::string in parameter. The "%s" is designed for C-style string : char* or char []. In C++ you can do like that :

#include <iostream> std::cout << YourString << std::endl; 

If you absolutely want to use printf, you can use the "c_str()" method that give a char* representation of your string.

printf("%s\n",YourString.c_str()) 

If you'd like to use printf(), you might want to also:

#include <stdio.h> 

While using string, the best possible way to print your message is:

#include <iostream> #include <string> using namespace std; int main(){ string newInput; getline(cin, newInput); cout<<newInput; return 0; } 

this can simply do the work instead of doing the method you adopted.
