/*          OUTPUT OF PROGRAM
            
	    Enter number of rows between (1-100): 2
	    Enter number of coloums between (1-100): 2

	    Enter elements of 1st matrix:
	    Enter element a11: 2
	    Enter element a12: 3
	    Enter element a21: 7
            Enter element a22: 5

            Enter elements of 2nd matrix:
            Enter element b11: 7
            Enter element b12: 5
            Enter element b21: 0
            Enter element b22: 1

	    sum of two matrix is:
	    9  8
            7  6
