strcmp c++

By Outrageous Oryx on Dec 07, 2020

int strcmp ( const char * str1, const char * str2 );

// returning value | indicates
// <0	the first character that does not match has a lower value in ptr1 than in ptr2
// 0	the contents of both strings are equal
// >0	the first character that does not match has a greater value in ptr1 than in ptr2
