Thread: Program won't compile

Edit:
My program will not compile, i'm not sure what the issue is. can anyone read it over for me

Code:

/*



#define NRows 21	// Dimensions for grid
#define NCols 51


#include <stdio.h>
#include <string.h>


/**** FUNCTION PROTOTYPES ****/
// Reset grid to original settings
void resetGrid(char grid[][NCols]);


// Add box to existing grid starting at (x, y) with specified width & height
void addBox(char grid[][NCols], int x, int y, int width, int height);


// Print current grid contents
void printGrid(char grid[][NCols]);
/***** END FUNCTION PROTOTYPES *****/


void main() {
	char myGrid[NRows][NCols];
 void main()
 {
 	int arr[nrow][ncols];
 	int rows,columns;

 	while(1)
 	{

 		scanf("%d %d",&rows,&columns);
 		if (((rows>20)|| (rows<0))||((columns>50)|| (columns<0)))
 			printf("Improper dimensions %i %i \n",rows,columns);
 		else
 			break;

 		}
 		else

 	}
 
 }
 void readval(int *numrows, int *numcolm,int *val,int rowmax,int colmax)

If you get Compiler errors, you should post the errors by cutting and pasting them between code tags.
If no errors, it will help if you state your OS name, Compiler/IDE name.

C is case sensitive as in "NRows" is not the same as "nrows".

how is it cheating if I've put in the effort to write the program. is this not similar to a tutoring process?
