Need help with writing function to populate the array

[appuguy]

Sample Input:o
0 4 0 5 0 8 0 7 0
Press any key to continue . . .

This is what I have so far for the code
[

#include <stdio.h>
#include <stdlib.h>

#define ARRAY_SIZE  81

int nArray[ARRAY_SIZE];

/*Function prototypes */
void PopulateArray( int nArray[9][9]);

void PrintArray(const  int nArray[9][9]);

void PopulateArray( int nArray[9][9])
{
   int i;
   int nSize;
   for(i=0 ; i < nSize ; i++)
   {
      printf("Enter value number %d:", i+1);
      _flushall();
      scanf("%d",&nArray[i]);
      
   }
      
}

void PrintArray(const int nArray[9][9])
{
   int i,j;
   
   for(i = 0; i <= 8 ; i++)
    {
   for(j = 0; j <= 8 ; j++)
      {
        printf("%2d",nArray[i][j]);
      }    
        printf("\n");
    }      
}  

int main(void)
{
  PopulateArray( int nArray[9][9]);
 
 PrintArray(const int nArray[9][9]);

 system("PAUSE");
 
 return 0;
}

I am getting the following errors in VC++

The following code should do the trick. Its not the most elagnant code as there is no validation for user inputs.

Also i have kept the interger array a 2 dimentional, if you want u can use a single dimentional array too (with approp changes), but keep it single dimentional across your as it makes the code more readable.

#include <stdio.h>

#define NROWS 3
#define NCOLS 3

static void popArray(int arr[NROWS][NCOLS])
{
	int rNo, cNo;

	for (rNo=0; rNo<NROWS; rNo++) {
		printf ("\nEnter row%d (%d values):", rNo, NCOLS);	//put approp message
		for (cNo=0; cNo<NCOLS; cNo++) {
			scanf("%d", &(arr[rNo][cNo]));
		}
	}
}


static void printArray(int arr[NROWS][NCOLS])
{
	int rNo, cNo;

	for (rNo=0; rNo<NROWS; rNo++) {
		printf("\n");
		for (cNo=0; cNo<NCOLS; cNo++) {
			printf("%d ", arr[rNo][cNo]);
		}
	}
}


int main(void)
{
	int myArr[NROWS][NCOLS];

	popArray(myArr);
	printArray(myArr);

	return 0;
}

Look at the lines specified. You are calling a function, but the parameters do not match the prototype you specified, such as calling with a char and the parameter needs a char*

C:\Documents and Settings\HP_Administrator\myfiletesting.c(44) : error C2198: 'PopulateArray' : too few actual parameters

Isn't this one obvious?

C:\Documents and Settings\HP_Administrator\myfiletesting.c(44) : error C2059: syntax error : ')'

Look at the line. Why would the errer point out a ')'?

What grade are you expecting for finishing his code for him? We prefer to help them solve the problems, not prove we can do better... :icon_wink:
