c++ - codeblocks shows error in a program but i can't find it - 


void print_lcs(int b[][], string x, int i, int j){      if(i==0 || j==0)         cout<<x[0];      if(b[i][j] == 1){         print_lcs(b, x, i-1, j-1);         cout<<x[i];     }     else if(b[i][j] == 2)         print_lcs(b, x, i-1, j-1);     else         print_lcs(b, x, i, j-1); }

this program don't know why first line has error. error messages given below:

error: declaration of 'b' multidimensional array must have bounds dimensions except first| error: expected ')' before ',' token| error: expected initializer before 'x'|

you have pass second (column) dimension of 2d array when declaring array in function arguments. in case: 

void print_lcs(int b[][column], string x, int i, int j) //replace column no of cols in 2d array
