To create an array use the new keyword, followed by a space, then the type, and then the number of rows in square brackets followed by the number of columns in square brackets, like this new int[numRows][numCols] . The number of elements in a 2D array is the number of rows times the number of columns.

How do you make a 3 3 matrix in C++?

int a[3][3] = { {2, 4, 1} , {2, 3, 9} , {3, 1, 8} }; int b[3][3] = { {1, 2, 3} , {3, 6, 1} , {2, 4, 7} }; If the number of columns in the first matrix are not equal to the number of rows in the second matrix then multiplication cannot be performed.
