#include <stdlib.h>


void case1();
void case2();
void case3();

ok ive done a case fuction and i still dont have the results printed out to screen but the other functions work.

it was to print results then end program

o i have the break in the wrong place it just jumps to case 4 with it being at that point

heres the code



case 3: printf("Lists stock\n");
{

FILE *fp; //file pointer
fp=fopen("stock.txt","r");
stock mylist[50];

when i put in curly brackets it jumps the printf statement and goes straight to break.

ok edited it


case 3:
printf("Lists stock\n");
{

FILE *fp; //file pointer
fp=fopen("stock.txt","r");
stock mylist[50];

then it just prints out loads of random numbers


case 3:
printf("Lists stock\n");
{

FILE *fp; //file pointer
fp=fopen("stock.txt","r");
stock mylist[50];

is there an easier way to print out my entire text file?

ok so ive done strcpy(). Its just the other error i cant seem to do with the relloc

heres the whole code:

Thanks Malcolm. That is very helpful I had aalready attempted what you posted but I had a few errors but I can see where I had gone wrong much appreciated
Thanks

ok so heres my snippet of code what i want to know is how i could get the prgram to show the whole array of the text file as data gets added to the file

printf("Lists stock\n");
{

Hi i have been able to write to a file but when i choose case 3 to read it just goes to write_info instead of read_infor all help would be appreciated thanks
