Question

Code looks like that

#include <cstdlib>
#include <iostream>

using namespace std;
#define n 3;
#define m 4;

int main(int argc, char* argv[])
{
    int arr[n][m];
    bool f=true;
    for (int i=0; i<n; i++)
        for (int j=0; j<m; j++)
            cin>>arr[i][j];
    for (int i=0; i<n; i++)
        for (int j=0; j<m; j++)
            if(arr[i][j]!=a[0][j])
                f=false;
    if(f)
            cout<<"Setirler eynidir.";
    else 
        cout<<"muxtelifdir";
    system("pause");
    return 0;
}

Getting bunch of errors

I can’t see any problematic piece of code. Any suggestions? What am I missing?

Answer 1

Since #define is a preprocessor directive, you’re making some mistakes in your array delcaration.

#define n 3;
#define m 4;

int arr[m][n];

// This translates into 
int arr[3;][4;];

You could fix it by removing the ; after the defines:

#define n 3
#define m 4

Or even better:

static const size_t n = 3;
static const size_t m = 3;

As the above will give you type safety elsewhere that you may use n or m.
