MAX ELEMENT IN An ARRAY

[yusufseedat]

hi guys. i am trying to find the max element in a given row of a 2d array. I have this code but it does not work. please assist

#include <iostream>
#include <string>
#include <cstdlib>
#include <cctype>
#include <stdlib.h>
#include "MatrixReloaded.h"
#include <algorithm>
using namespace std;

const int row=3;
const int col=4;
typedef int functionArray[col][col];
functionArray myArray;


namespace MatrixReloaded
{

void Max()
{
	row=2;
	int largest=myArray[row][0];

	for ( col=1;col <col;col++)
		if(largest <myArray[row][col]);
	       largest=myArray[row][col];

	       cout << "The maximum for row 2 = " << largest << endl;

}

void min()
{

}
void average()
{

}

}t the code you need help with here.

You've defined "Row" and "col" as const ints at the beginning, but you reuse those variables in Max(). You can't assign to a const int.

Also look at the loop:

for ( col=1;col <col;col++)

"col<col" will never EVER be true: a variable is never less than itself.

But you're REALLY close to having it right. "Row" and "col" define the bounds of the array. Use different variables (maybe r and c) as indexes INTO the array.

got it...working perfectly. thanks dave

Line 12 looks suspicious.

typedef int functionArray[col][col];

Do you mean:

typedef int functionArray[row][col];

The error is harmless since you're merely allocating an extra row.
