Output

    Enter number of Rows :2 
    Enter number of Cols :3 

    Enter matrix elements : 
    Enter element [1,1] : 1 
    Enter element [1,2] : 2 
    Enter element [1,3] : 3 
    Enter element [2,1] : 4 
    Enter element [2,2] : 5 
    Enter element [2,3] : 6 

    Transpose Matrix is :
    1	4	 
    2	5	 
    3	6
