string Comparison
Solution 1
Since you're using std::string
, strcmp
is unnecessary -- you can just use <
, ==
, !=
, etc.
Solution 2
Your includes:
Since you are including standard headers, they should be in <>
#include <string>
#include <iostream>
#include with "" is generally used for your own header files, not standard header files.
You are using C++, and therefore need not use strcmp. In C++, you can simply use == & != to compare two strings.
if (my_string == my_string2) result = 0;
else result = 1;
Also, if you want to convert a string to a const char*, you can use mystring.c_str()

I want to compare two user input strings, but not able to do so...
#include "stdafx.h" #include "iostream" #include "string" using namespace std; int _tmain(int argc, _TCHAR* argv0[]) { string my_string; string my_string2; cout<<"Enter string"<<endl; cin>>my_string; cout<<"Enter 2nd string"<<endl; cin>>my_string2; cout<<my_string<<" "<<my_string2; strcmp(my_string,my_string2); int result; result= strcmp(my_string,my_string2); cout<<result<<endl; return 0; }
This error is appearing. Error 1 error C2664: 'strcmp' : cannot convert parameter 1 from 'std::string' to 'const char *' c:\users\asad\documents\visual studio 2008\projects\string\string\string.cpp 23 String
