There is a std::string data type in the C++ Standard Template Library (STL). We can use it to replace characters in an array, since it has more flexibility features. The biggest advantage to using this data type instead of a characters array is that the size of std::string can be extended dynamically in runtime. Other functionalities that it has are as follows:
- getline(): This function is used to get input from the user and then store it to a character stream in memory
- push_back(): This function is used to insert a character at the end of the string
- pop_back(): This function is used to remove the last character from the string
- size(): This function is used to retrieve the number of character ...
