Need help storing character values into a 2D array

costadali (6)
So I am almost finished with this program, and I need to take a set of int values from a previous array, go through each value, determine if the value is >= 128, and if it is then display and astrix ("*"), and if its not display an empty space (" ").

How do I store character values into an array? (Look towards the bottom of my code).

-Thanks everyone

The mistake is probably on lines 68 and 72.

You do
1
2
 
charImage[i][j] = "*";
charImage[i][j]= " ";


This is a mistake. Double quotes (" ") are used for strings. Single quotes(' ') are used for char

Like this:
1
2
 
charImage[i][j] = '*';
charImage[i][j]= ' ';
