Question

Can anyone pls let me know the exact c++ code of case sensitive comparison function of string class?

Answer 1

std::string str1("A new String");
std::string str2("a new STring");
if(str1.compare(str2) == 0)
    std::cout<<"Equal";     // str1("A new String") str2("A new String");
else 
    std::cout<<"unEqual";   //str1("A new String") str2("a new STring") 

compare() returns an integral value rather than a boolean value. Return value has the following meaning: 0 means equal, a value less than zero means less than, and a value greater than zero means greater than
