Error declaring variables in C?

Question

I'm getting an error when trying to compile this line (C), my compiler doesn't seem to be recognizing the previous declaration of "nRows, nCols":

void scalarMultiply (int nRows, int nCols, int matrix[nRows][nCols], int scalar);

Is there something wrong with it?

It's from a Stephen kochan's book, so I'm guessing it's got something to do with my compiler which is MinGW Developer Studio 2.05

Answer 1

Hi,
void scalarMultiply (int nRows, int nCols, int matrix[nRows][nCols], int scalar);


here, you can not give nRows, nCols as index to arrays.
you can give it as matrix[][] or int **matrix.
********
and anyhow giving parameter description in case of array is to make sure that they are of same type and order.

Answer 2

Just wrong code, I'm not sure but appears this author is not a C programmer.

int matrix[nRows][nCols]
replace it with int** matrix, for the declaration you wrote.

Answer 3

i comprehend in a lot of of the newer langugaqes, you're waiting to outline an array per a variable, yet i don't believe of that you'll in C++. it ought to should be a consistent, being the biggest available fee for that array length.

Answer 4

you can not use int matrix[inRows][nCols] rather use a pointer

Answer 5

u cant define prototype like this,strictly compiler will expect only data types, but u can define variables,but cant use them..

Answer 6

try another compiler like cygwin or Dev C
