Question

passing values problem

Asked by: Vasconcelos

for example i have a bidimensional stack and the stack top has a GLOBAL variable
int top = 0;
char stack[MAXLINES][MAXCOLUMS];

and for example i wanna do this:

int find_repeated(char *p, int t)
{
    int i = 0, j = 0;
    int count = 0;
    for(i = t - 1; i >= 0; i--)
    {
        for(j = i - 1; j >= 0; j--)
            {
                  if(strcmp(p[SIZE][i], p[j][SIZE]) == 0)

my question is how do i call the the stack onto the function (char *p, int t)?
if i could have a detailed explanation i would be thankfull.

btw sorry for the bad english :)

If you are passing a two-dimensional array to a function:

// 2D array
int myarray[NO_OF_ROWS][NO_OF_COLUMNS];

// function call
myfunc(myarray);

// function's declaration
void myfunc(int myarray[][NO_OF_COLUMNS])

or

void myfunc(int (*myarray)[NO_OF_COLUMNS])

hope this helps!!

Also, I assume you meant :

                  if(strcmp(p[i], p[j]) == 0)

instead of :

>>                   if(strcmp(p[SIZE][i], p[j][SIZE]) == 0)

The strcmp function takes strings (char*) as parameters. What you were passing were single char's, and depending on the vale of SIZE, they might even have been invalid (ie. not part of any of the strings on the stack).

can use char** instead of only char*

>> can use char** instead of only char*

If you are referring to the first parameter of the find_repeated function, then : no, you can't. A char** does not have the same memory layout as a char[][].
