number of characters in stdin buffer entered by user

[satro]

Console app. User entered some characters and clicked ENTER.

How to know the number of characters in stdin buffer that user entered from keyboard?

I just want to allocate storage space for the array of input characters.

Ya, you have to use a dynamic array. Look up how to do it because I'm not completely sure about the syntax.

Just use std::string.

#include <iostream>
#include <string>

int main()
{
    std::string input ;
    std::cout << "Give me some input: " ;
    std::getline(std::cin, input) ;

    std::cout << "You entered \"" << input << "\"\n" ;
}
