Seg Fault Core Dumped [closed]

I'm having this error in the code and I can not find the problem, can someone point me to what I'm doing wrong? What the code does: I get row and column of matrix A, after matrix B, check if they can be multiplied. I get the values of matrix A and after matrix B. At that moment the error occurs. After that you should multiply the matrices and print the resulting matrix.
