Thread: Can't seem to understand what's wrong with this program :(

Post your code in [code][/code] bbcode tags.

What is the program supposed to do and how does it not work?

Sorry, but a linker error usually means you have no program to run.

I suggest you at least post all the error messages you can see, and let us figure out what is really going on.

Code:

#include<iostream.h> //should be #include<iostream>
                     // iostream.h is outdated include - if you are using it 
                     //it is time to change the compiler
void middle(int a[][10], int n)
{ 
    int i,j;
    cout<<"Middle Column:- "; //should be std::cout
    for(i=n/2,j=0; i<n; j++)
    {
        cout<<a[i][j]<<" ";
    }


    cout<<"Middle Row:- ";
    for(j=n/2,i=0; i<n; i++)
    {
        cout<<a[i][j]<<" ";}
}


void main() //read FAQ it shoudl be int main()
{ 
    int size,a[10][10]; //think about using std::vector
    cout<<"Enter the size : ";
    cin>>size;
    cout<<"Enter the elements of the matrix : ";
    for(int i=0; i<size; i++)
    { 
        for(int j=0; j<size; j++)
            cin>>a[i][j];
    }
    for(i=0; i<size; i++) //you need int i here as well - again your compiler is outdated
    { 
        for(int j=0; j<size; j++)
            cout<<a[i][j]<<" ";
        cout<<"\n";
    }
    middle(a,size);
}

the first for loop in middle()... what.
