Thread: Problem with cast

Code:

#include <stdio.h>
#include <stdlib.h>
#include <assert.h>

FILE *ifp;
int *array1;
int length;
static int*
ReadData( const char *ifp, *length );
FILE *ofp;
char outputfile[100];
int main( int argc, const char *const *argv ) {
        /* Get filename from command line. */
        if( !(ifp = fopen( argv[1], "r") ) ) {
                printf("Can't open the data file %s \n", argv[1]);
                exit (1);
        }
        array1 = ReadData( *ifp, &length );
        if( fclose(ifp) ) {
                printf("File close error.\n");
        }
        return 0;
}
static int*
ReadData( const char *ifp, *length ) {
        int size;
        int ch;
        int prev;
        int i;
        prev = '\n';
        *length = 0;
        size = 1;
        array1 = malloc(sizeof(*array1) * size);
        if( array1 == 0 ) return 0;
        while( fscanf( ifp, "%d", &i ) != EOF ) {
                while( *length >= size - 1 ) {
                        size *= 2;
                        array1 = realloc(array1, sizeof(*array1) *size);
                        if( array1 == 0 ) return 0;
                        }

                array1[*length] = i;
                (*length)++;
        }
        printf("The number of items is %d \n", length);
        return array1;
}

I get the following errors I think it had to do with length.

Code:

:9: parse error before `*'
:25: parse error before `*'
: In function `ReadData':
:31: invalid type argument of `unary *'
:36: invalid type argument of `unary *'
:42: invalid type argument of `unary *'
:43: invalid type argument of `unary *'

ReadData( const char *ifp, <insert a type here> *length );

What about them?
That one problem fixed results in some completely different problems.

Think about them for a while, try and fix them, then post back if you're still stuck.
