Printing ASCII Code

[Egz0N]

Hello CodeCall Members,

Today I'd like to Show you How to Make a Simple Program that Will Print us the ASCII Code .. using C++ ..

Ok..! ,

First of all we declare 2 variables .. ('i' as an integer and 'a' as a character)

int i;
char a;

then we use this loop:

for (i=30;i<=255;i++)

the "i" starts from 30 because the other characters before 30 are some special characters (like ENTER etc..) .. so we say that from i=30 till i<=255 increasing the 'i' for 1 ..


the 'a' character becomes the character with the ASCII code 'i' .. using this command ..

a=i;

now, using "iomanip" we format the output .. the iomanip code will look like as following:

        cout << setw(2)
             << a
             << setw(6)
             << i;

.. the "setw(2) will reserve 2 spaces for the character 'a' .. and setw(6) will reserve 6 spaces for the number 'i' ..


finally the code will look like the following:

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

int main()
{
    int i;
    char a;
    
    for (i=30;i<=255;i++)
    {
        a=i;
        cout << setw(2)
             << a
             << setw(6)
             << i;
    }
    cout << endl;
    
    return 0;
}

.. and the console application will look like the following:

Nice way to generate a quick ASCII table.

Interesting, but, what are ASCII values?

Interesting, but, what are ASCII values?

The American Standard Code for Information Interchange (acronym: ASCII) is a character-encoding scheme based on the ordering of the English alphabet. ASCII codes represent text in computers, communications equipment, and other devices that use text. Most modern character-encoding schemes, which support many more characters than did the original, are based on ASCII.

Nicely written! Simple and easy to follow. +rep

A lot of C++ coders don't even know iomanip exists. Your tutorial appeases me, but it would be clearer if you cast i to a char first.

a = (char) i;

Not necessary, maybe, but clearer.

Anyway, great little tutorial! Plus rep

ahh .. thanks ..
