Accessing a string though a pointer array

BombaD · 03-10-2015, 07:32 AM

I'm wondering how to access Buffer 1 and 2 via the pointer array;

Code:

char *BufPtrs[3];
        char Buffer1[64];
        char Buffer2[64];
        BufPtrs[0] = Buffer1;
        BufPtrs[1] = Buffer2;
        BufPtrs[2] = NULL;

I thought that if I were to access Buffer1 via BufPtrs[0], I would simply just put an * to it before printf()-ing or store it in a char[] (equivalent to a string).

BufPtrs[0] is a char * so just use it that way.

clean compile with gcc -Wall

Code:

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

int main()
{
int i;

char *BufPtrs[3];
        char Buffer1[64];
        char Buffer2[64];
        BufPtrs[0] = Buffer1;
        BufPtrs[1] = Buffer2;
        BufPtrs[2] = NULL;

i=0;
Buffer1[i++]='Q';
Buffer1[i++]='W';
Buffer1[i++]='E';
Buffer1[i++]='\0';

printf("THING %s HERE\n", BufPtrs[0]);
exit(0);
}
