Explanation / Answer

You have a large number of errors in your program. I have fixed and commented a number of them so that your program compiles. You will need to finish implementation of your project. I would really recommend studying your book more and adding brackets around your loops to make the code easier to read and debug. In addition I would recommend sticking to a standard naming convention for your variable names. #include #include #include #include using namespace std; // These need to be outside of main void ReadMatrix(float [][25], int*, int*); void PrintMatrix(float [][25], int, int); void PrintMatrixTranspose(float [][25], int, int); int main(int argc, char *argv[]) { float matrix[25][25]; int numrows, numcols; ReadMatrix(matrix, &numrows, &numcols); PrintMatrix(matrix, numrows, numcols); // Needs to be defined before using PrintMatrixTranspose(matrix, numrows, numcols); // Needs to be defined before using system("pause"); return (0); // Main returns 0 on success } void ReadMatrix(float matrix[][25], int*numrows, int*numcols) { fstream namefile; // nameFile is case sensitive string filename; cout (*numcols); for (int i=0; i matrix[i][j]; } } for (int i=0; i
