[C] need help with array

[ares623]

---

hello ninyo.
nag-lisod ko sa amo project sa skul.. naa koy 3 arrays.. i assign values to them using for loops and scanf. then the program asks if i want to add another value to the array.
it works for the first 2 or 3 increments to the array but after that, one of the values of the array is messed up.. please help.
here is the code, i added some comments to try and clarify it a bit:

#include<stdio.h>
#define TRUE 1
#define FALSE 0
int check(char ans,char big,char small){
	if(ans == big || ans == small){
		return TRUE;
	}else{
		return FALSE;
	}
}
ADDITEM(){
	/*initialize*/
	int x,last,i;
	printf("Enter # of items: ");
	scanf("%d",&x);
	int code[x], price[x];
	char ans, name[x][30];
	ans = 'y';
	last = i = 0;
	while(check(ans,'Y','y')){
		/*ask for input*/
		for(i = last;i < x;i++){
			printf("Enter item code #%d: ",i+1);
			scanf("%d",&code[i]);
			printf("Enter name of item #%d: ",i+1);
			scanf("%s",&name[i]);
			printf("Enter item price #%d: ",i+1);
			scanf("%d",&price[i]);
		}
		/*print list of values*/
		printf("\n----------LIST-----------\n");
		for (i = 0;i<x;i++){
			printf("\nItem code #%d: %d",i+1,code[i]);
			printf("\nItem name #%d: %s",i+1,name[i]);
			printf("\nItem price #%d: %d",i+1,price[i]);
			printf("\n");
		}
		last = x;	/*assign last value of x to variable for reference*/
		/*ask user to increment list*/
		printf("\n\nAdd another item[Y/N]? ");
		scanf("%s",&ans);
		if(check(ans,'N','n')){
			break;	
		}else if(check(ans,'Y','y')){
			x++;	
		}else{
			while(!check(ans,'N','n')||!check(ans,'Y','y')){
				if(check(ans,'N','n')||check(ans,'Y','y')){
					if(check(ans,'Y','y')){
						x++;
					}
					break;
				}else{
					printf("Y or N?");
					scanf("%s",&ans);
				}
			}
		}
	}
}
main(){
	char choice;
	choice = '\0';
	printf("START [Y/N]? ");
	scanf("%s", &choice);
	while(!check(choice,'n','N')){
		if(check(choice,'Y','y')){
			ADDITEM();
		}else if(check(choice,'n','N')){
			break;
		}
	}
}

header file na bro??

dili.. command line executable.. mao na ang working code. suwayi daw save and compile bsin mka-tabang ka nko. hehe. thanks for looking.

-------------
and i have another question.
say i have 2 functions. one is ADDITEM(), the one i posted, and the other is DISPLAYITEM(). so they need to be able to access the same arrays right? unsaon man na?

their is a problem on the way you dynamically allocate the size of your array..use malloc or calloc

[IcEmElt]

// int code[x], price[x];
// char ans, name[x][30];


int code *x,*price;
char ans,**name;


sample use of malloc
malloc(sizeof(int) *x);
malloc(sizeof(int) *x*30);

thanks everyone for the suggestions.. pero ni-ana man amo sir nga dili nalang toh ang increment2x sa array, so wla na ni nga problem.
pero unsa man nang 'malloc()' nga function? pwede simple explanation? hehe.

malloc() actually allocate memories space for a particular variable!!

[limunsito]

malloc = a function that calls a block of memory from the heap
