Inputing multiple entries in a 2D array on one line

I am creating a program that allow the dimensions and values of matrices to be input and then added and subtracted.
I can allow the user to input entries into a 2D array using two 'for' loops but the user cannot visually see the matrix being formed. By this I mean that the user enters the input as:
[1][1]: 23
[1][2]: 54
[1][3]: 67
etc...
but I want the user to be able to input the values to the matrix like this:
[ 23 54 67 ]
[ 64 78 92 ]
etc.
is there any way to write the program so that multiple entries can be input without pressing enter? I want the equivalent of:
cin<<array[1][1]<<array[1][2]<<array[1][3];
cin<<array[2][1]<<array[2][2]<<array[2][3];
but since the width of the matrix is not predetermined I can't see how to do this since I need to use two for loops. Have I explained this well enough?
