Thread: Getchar & Structure Problems

Hi, having a problem with something I am trying to do in C. This is the code I have:

#include <stdio.h>

int main()
{

#define MAX 10

int i;

struct list_details
{
char make[45];
char model[45];
} carList[10];

for(i=0; i < MAX;i++)
{
printf("Enter the make : \n");
scanf("%s", &List[i].make);
printf("Enter the model : \n");
scanf(%s", &List[i].model);
}

return 0;
}


This keeps asking for a make and model for up to 10 times, however I want it so that you can input up to 10 times but can also quit before if needed. E.g. if you only want to put 3 records in then you can quit after entering the third record. I have been trying this using getchar() but just can't seem to get it to work.

Please help.

You need to build this test into your code

Eg.

Code:

for(i=0; i < MAX;i++)  { 
   printf("Enter the make (or QUIT) : \n"); 
   scanf("%s", List[i].make);  // & not needed for char arrays
   if ( strcmp(List[i].make,"QUIT") == 0 ) break;   // all done
   printf("Enter the model : \n"); 
   scanf(%s", List[i].model); 
}

Also

Code:

struct list_details { 
char make[45]; 
char model[45]; 
} carList[MAX];   // use the #define

Thanks a lot!, that works just great!
