std::string::find might meet what you want, see this

string s1 = "I say that the site referenced here is not in configuration database. need to check"; 
string s2 = "the site referenced here is not in configuration database";

if (s1.find(s2) != std::string::npos){
    std::cout << " found " << std::endl;
}

For C/C++, you can use strstr():

const char * strstr ( const char * str1, const char * str2 );

Locate substring

Returns a pointer to the first occurrence of str2 in str1, or a null pointer if str2 is not part of str1.

If you insist on pure C++, use std::string::find:

size_t find (const std::string& str, size_t pos);

Find content in string

Searches the string for the content specified in either str, s or c, and returns the position of the first occurrence in the string.

string sourceString = "I say that the site referenced here is not in configuration database. need to check";

string stringToFind = "the site referenced here is not in configuration database";

sourceString.find(stringToFind); This method call will return you the postion of type size_t

Hope this helps you
