Structs, strtok, segmentation fault
- by FILIaS
I'm trying to make a programme with structs and files.The following is just a part of my code(it;s not all). What i'm trying to do is: ask the user to write his command.
eg. delete John eg. enter John James 5000 ipad purchase.
The problem is that I want to split the command in order to save its 'args' for a struct element. That's why i used strtok. BUT I'm facing another problem in who to 'put' these on the struct.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX 100
char command[1500];
struct catalogue
{
char short_name[50];
char surname[50];
signed int amount;
char description[1000];
}*catalog[MAX];
int main ( int argc, char *argv[] )
{
int i,n;
char choice[3];
printf(">sort1: Print savings sorted by surname\n");
printf(">sort2: Print savings sorted by amount\n");
printf(">search+name:Print savings of each name searched\n");
printf(">delete+full_name+amount: Erase saving\n");
printf(">enter+full_name+amount+description: Enter saving \n");
printf(">quit: Update + EXIT program.\n");
printf("Choose your selection:\n>");
gets(command); //it save the whole command
/*in choice it;s saved only the first 2 letters(needed for menu choice again)*/
strncpy(choice,command,2);
choice[2]='\0';
char** args = (char**)malloc(strlen(command)*sizeof(char*));
memset(args, 0, sizeof(char*)*strlen(command));
char* curToken = strtok(command, " \t");
for (n = 0; curToken != NULL; ++n)
{
args[n] = strdup(curToken);
curToken = strtok(NULL, " \t");
*catalog[n]->short_name=*args[1];
*catalog[n]->surname=args[2];
catalog[n]->amount=atoi(args[3]);
*catalog[n]->description=args[4];
}
return 0;
}
I get a warning (warning: assignment makes integer from pointer without a cast)
for the lines:
*catalog[n]->short_name=*args[1];
*catalog[n]->surname=args[2];
*catalog[n]->description=args[4];
As a result, after running the program i get a Segmentation Fault...
Any help? Any ideas?
