x++ not incrementing

[Feemix]

i am converting each character from string into ASCII and i need size of array "x" to store them in array why didnt it increments "x" after cout?

  
#include <iostream>
#include <string>
using namespace std;

void convertToASCII(string letter)
{
	int x=0;
    for (int count = 0; count < letter.size(); count++)
    {

        x++; // worked
        char x = letter.at(count);
        cout << int(x) << endl;
	//	x++; not worked why?
		
    }
	cout << x;
	
}

int main()
{
    string plainText;

    cout << "Enter text to convert to ASCII: ";
    cin >> plainText;
    convertToASCII(plainText);
    return 0;
}

You have two variables named 'x'. One is an int, declared on line 8, the other is a char declared on line 13.

    int x=0;  // <- "int_x"
    for (int count = 0; count < letter.size(); count++)
    {

        x++; // <- increments int_x
        char x = letter.at(count); // <- "char_x"
        cout << int(x) << endl;  // <- prints char_x as an integer
	//	x++; <- increments char_x... NOT int_x
		
    }
    cout << x; // <- prints int_x
