Transforming a string into ASCII

Transforming a string into ASCII code using int() and the 'while' loop. Good for beginners in programming and C++.

ASCII = computer data exchange standard: a standard that identifies the letters of the alphabet, numbers, and various symbols by code numbers for exchanging data between different computer systems.

Every character has a different number under which it is stored on your computer. There are 256 different ASCII codes (the possible values a byte can hold), that is why a character takes one byte.

// Transform a word into ASCII code

#include <iostream>
using namespace std;
int main()
    char word[32];
    int x = 0;
    cout << "Please enter the word (maximum 32 characters):\n";
    cin >> word;
    cout << "The ASCII for this word is:\n";
    while (word[x] != '\0')    // While the string isn't at the end...
        cout << int(word[x]);    // Transform the char to int
    cout << "\n";
    return 0;

With ‘while’ we loop trough the array and convert every character using int(word[x]) to its ASCII value. If we hit the ‘\0’ (end of the string), the while loop returns false and ends.

There is more to say about ASCII than I said here… Google can help you 😉 .
