Really i need help to complete my program but i don't know how to fix the errors ..

the program is about 2 Dimensional Arrays matrix operations

i wrote the whole program but there is some mistakes plz i need help to finish it im too confused !!

#include <iostream>
using namespace std;


template < typename T >

class Matrix
{
	private: 
		T M[100][100];
		int rowsize;
		int colsize;

	public:

		void set_par(T x, int rp, int cp)
		{
			M[rp][cp]=x;
		}

		Matrix ( int r , int c )
		{
			rowsize = r;
			colsize = c;
		}

		void add ( T x , int rp , int cp )
		{
			M[rp][cp] += x;
		
		}

		T retrieve ( int rp , int cp )
		{


			return M[rp][cp];

		}

		int getrow ()
		{


			return rowsize ;
		}

		int getcoluomn ()
		{

			return colsize ;
		}

		void display()
		{
				for ( int i=0 ; i<rowsize ; i++)
		
				{
					for ( int j=0 ; j<colsize ; j++)
					{	cout<< M[i][j];
					}
					cout<<endl;
				}
		}
};


template < typename T >

	{
	for ( int i=0 ; i<r ; i++)

	}

}

what compiler are you using?

Take the error messages one at a time, then recompile to get a new list. For example, main() is missing declaration of variable i in a lot of places. The declaration of i in the first for loop is only valid for that loop. I'd suggest declaring it at the beginning of main(), like you did variable x

> i wrote the whole program but there is some mistakes
And until you adopt a better approach to writing programs, the same mistakes will keep arising.

DO NOT try to write the whole thing in one edit, press "compile" whilst sacrificing some animal to the programming gods, then posting on a message board "it doesn't work".

Fixing code is a basic skill, learn how to do it.

Great advice :)
