Thread: Printing values and their ascii symbol with for loops.

Hi, Im trying to make a program that scans through the numbers 32-234 and then show both value and ascii symbol.
The result must be presented in several columns and not in rows.

32 33 ! 34 " wrong.

32
33 !
34 " right.

Im having problems with the nested for-loops.

this is how I run through 32-234 and present it the wrong way:

Code:

for(int i = 32; i <= 234; i++)             {
                ch = static_cast<int>(i);
                cout << setw(4) << i  << setw(4) << ch;                
            }

My question is how to set up the for loops.

The outer loop runs the rows, inner the columns.

1st loot checks the value and ascii symbol

2nd checks the rows

3rd checks the colums

The following will do it for you....

Code:

#include <windows.h>
#include <iostream>
using namespace std;

int main()
{
    system ("Color f9");
    HANDLE hOut;

    int i;
    int x=0;
    int y=10;

    COORD Position;
    hOut=GetStdHandle (STD_OUTPUT_HANDLE);

    for (i=32;i<=255; i++)
    {
        Position.X=x;
        Position.Y=y;
        SetConsoleCursorPosition(hOut,Position);
        cout.width(3);
        cout << i << "  " << (unsigned char)i << flush;
        ++y;
        if(y>38)
        {
            y=10;
            x+=10;
        }
   }

   cout<<endl<<endl<<endl<<endl<<endl<<endl;

    return 0;
}
