Passing a matrix in a function (C)

Question

I have an issue passing a matrix to a function in C. There is the function I want to create:

void ins (int *matrix, int row, int column);

b

Answer 1

If you have a modern C compiler you can do the following for 2D matrices of any sizes

void ins (size_t rows, size_t columns, int matrix[rows][columns]);

Important is that the sizes come before the matrix, such that they are known, there.

Inside your function you then can access the elements easily as matrix[i][j] and the compiler is doing all the index calculations for you.
