Putting data from a variable into an array - c

Question

Hello good people of Stack Overflow. Need some help with my code. I am basically trying to put the data that is stored in the variables itemCode, itemName, pricepu, and stock into array and I have NO IDEA how to do so..
Here's my code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>
#include <math.h>
#define totalitems 20
#define maxitems 300
void mainmenu(void);
void alt_menu(void);
void purchase(void);
void edit_item(void);
void update_item(void);
void del_item(void);
void shw_item(void);
void invent_menu(void);
void alt_invent_menu(void);
void daily_trans(void);
void exit_escape(void);
void back_inventmenu(void);
void back_menu(void);
void gst_array(void);
char invent_back, back; //global declarations
char input, newinput;
char *barcode;
char taxitems[20][20];
char ntaxitems[20][20];
char line[2048];
char *itemCode[20][20];
char itemName[20][20];
unsigned char pricepu[10][20];
char stock[10][20];
int i, ret, quantpurchase;
double total;
void purchase() {
char exitcode[] = "-1";
barcode = (char*) malloc(5);
printf(" Please key in the barcode number of the product: ");
scanf(" %s", barcode);
while(strcmp(exitcode, barcode) != '\0') {
double priceint;
FILE *gst = fopen("gst.txt", "r");
FILE *ngst = fopen("ngst.txt", "r");
printf("\n");
printf("\n Item Code Entered: %s\n", barcode);
while(fgets(line, sizeof(line), gst) != NULL) { //while fgets does not fail to scan a line
if(sscanf(line, "%[^;];%[^;];%[^;];%[^;]", itemCode, itemName, pricepu, stock) != 4) {
//If sscanf failed to scan everything from the scanned line
//%[^;] scans everything until a ';'
printf("Bad line detected\n");
exit(-1); //Exit the program
}
for (i=0; i < totalitems; i++) {
if (strcmp(itemCode[i], barcode) == '\0') {
printf("\n");
printf(" Item Found.\n");
printf("\n");
printf("===========================================================================\n");
printf(" Item code\t Item name \t\t\tPrice\t Stock Available \n");
printf("===========================================================================\n");
printf(" %-10s\t %-16s\t\t%s\t %s\n", itemCode, itemName, pricepu, stock);
printf("\n");
printf("\n");
priceint = strtod(pricepu, (char **)NULL);
printf(" How many would you like: ");
scanf("%d", &quantpurchase);
total = priceint * quantpurchase;
printf(" %.2lf\n", total);
for (i=0; i<maxitems; i++) {
taxitems[0][i] = itemCode[i];
printf(" %s", taxitems[0][0]); //HERE'S WHERE I NEED HELP
}
purchase();
}
}
}
}
}
It's not giving me my desired result. Basically say "AG001" is currently stored under the variable "itemCode", I want to move that into an array. Appreciate all the help I can get. Thanks.

taxitems[0][i] = itemCode[i];
You can't copy char arrays with simple assignment. You need to use the strcpy() function instead.
strcpy( taxitems[0][i], itemcode[i], strlen(itemcode[i]);
You will need to add
#include <string.h>
to your code. You can find the reference to strcpy() function here
