Write a program to read a matrix of size m x n from the keyboard and display the same on the screen using functions.

Obviously homework for a class.

If we do your homework for you, how will you ever learn??

If you would *TRY* to write the code, if you would mostly get it working and have some bug, *THEN* you might get help.

But nobody should do homework for you.

Please correct my code.

#include <iostream>
using std::cout;
using std::cin;

int matrix(void);
int main()
{
matrix();
return 0;
}
int matrix(void)
inta[50] [40],i,j,m,n;
cout << "Enter dimention of matrix\n";
cin >> m >> n;
cout << "Enter elements of matrix\n";
for(i=0;i<m;i++)
for(j=0;j<n;j++)
cin >> a[i] [j];
cout << "\nThe given matrix is: ";
for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
cout << a[i] [j];
return o;
}

Your function matrix is missing its starting { character.

You are missing a space after the keyword int.

You have a bogus { aft the next-to-last "for".

You are using return o; but you never define the variable o.

Those I see just off the top of my head. There might be other errors.

What happens if the user enters 45 as the matrix dimension?

Ever heard of COMMENTING code?
