Answer to Question #43348 in C++ for ragmar

Question #43348
what do you mean by "if(!strcmp(subject, index))" i get from this segment of code and i didnt get what does the ! really does char name[ ] = "a"; char profession[ ] = "b"; char subject[ ] = "c"; cout << "please enter a word to search: "; cin >> index; if(!strcmp(name, index)) cout << "first letter" <<endl; else if(!strcmp(profession, index)) cout << "second letter" << endl; else if(!strcmp(subject, index)) cout << "third letter" << endl;
Expert's answer
strcmp function returns 0 if the strings are equal. Computer "thinks" that everything that is not zero is true, and zero is false.
So the line which confused you is read as "if not strcmp(name, index) equals true" or "if(strcmp(profession, index) == 0)"
