Let the two matrix to be multiplied be A and B. You write the code to do it once, and then you can "call" it as many times as you like.
You are on the right track, actually. When we are obtaining the value at C[i][j], row i of matrix A and column j of matrix B are multiplied element wise. Note that the number of columns in the first matrix should be the same as the number of rows in the second matrix.
Now, our task is to find what numbers go into each of the positions of matrix C with d rows and f columns. An integer int is different than a floating-point double is different than a character charetc.
Your big function does two things -- it multiplies the arrays and it displays the result. So, in your code, you are trying to pass a two-dimensional array int firstarray as an integer int firstarray. In order to pass the array, you must make the argument to your function take an array of the same type: A function should do just one thing.
That is your main problem. After that, your main function can say: Within the loop, A[i][k] and B[k][j] are multiplied and the product obtained is added to the existing value of C[i][j]. Even though they have the same name.
An inner loop has the loop counter j ranging from 0 to f. An loop is used whose counter k, ranges from 0 to e This body will in turn consist of a loop.
Try to break it down into two functions: At any iteration of the loop, i refers to the row number and j to the column number of the position in matrix C that we are trying to fill. A three level nested loop is used to perform the multiplication.
Now, within the body of the inner loop, we have to write some code which will calculate the value to be filled. The trick is to make sure the type of everything matches. Another thing to notice is that there is no single number that can represent a matrix a whole bunch of numbers.
We can also declare a variable sum before the start of the innermost loop, add the element wise products to this variable and assign the resulting sum to C[i][j].
So there is no point in trying to obtain a single number that does it.
