string Comparison

Answer 1

Since you're using std::string, strcmp is unnecessary -- you can just use <, ==, !=, etc.

Answer 2

If you want to use strcmp note that it takes different parameters than the ones you used.

Answer 3

Another way to do this is also

result= strcmp(my_string.c_str(),my_string2.c_str());

Answer 4

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()
