Hi I was wondering if there is an alternative of str.substring() in string.h. If not, what is an efficient alternative? >Solution : Assuming that we all agree that using c++ it is safer and more professional to use the standard library tools.

Hi everyone I have a simple task in C++: -> writing a program that takes a string from user input and loops over the characters in the string via a pointer. If I understand correctly, then a previously declared string name; variable can also be accessed via const char*, implying that I can declare a… Read More const char* pointer handling (C++)
