Thread: matrix

Hi, I have a few questions about this matrix "table"
I can't find any wrong in it
but errors keeps appear
C2057 expected constant expression
C2466 cannot allocate an array of constant size 0
C2087: 'table' : missing subscript
C2133: 'table' : unknown size

here's the code
thanks for helping

Code:

int lcs(string str1, string str2, string & sequence) {
    int rows=str1.length() + 1, cols=str2.length() + 1, position, seqLength;
    int table[rows][cols];
    int i, j;
    ......

int main() {

    string inp, first, second, outp;
    int seqlen;

    getline(cin, inp);
    first = stripBlanks(inp);

    getline(cin, inp);
    second = stripBlanks(inp);

    seqlen = lcs(first, second, outp);
    ......

Seems that rows and cols are no constants.

You can not initialize arrays (matrix is multiple arrays) with non-constant variables (that is, the program can not decide at run-time).
However, if you want to be able for the program to decide the size of the arrays you can use pointers.
