Properly buffering and validating string - c

Question

I am getting a bit of an error in my program, it is somewhat basic but here is my error: I am trying to properly input a series of strings into a structure and it seems like user input is ending at the wrong spot.
#include <stdio.h>
#include <string.h>
#define buffer 256
struct Fisher
{
char SSN[8]; //9 digit max
char First_Name[12];
char Last_Name[15];
char Phone[10];
char Email[35];
}typedef Fisher;
void getFisher(Fisher* pfisher, int i);
void dispFisher(Fisher* pfisher, int i);
void Fisherman_Menu(Fisher* pfisher, int i);
int main()
{
int i = 0;
Fisher fisherarray[3];
Fisher* pfisher = &fisherarray[0];
Fisherman_Menu(pfisher, i);
return 0;
}
void Fisherman_Menu(Fisher* pfisher, int i)
{
for(;;)
{
fflush(stdin);
printf("-1-Register Fisherman\n");
printf("-2-Search Fisherman\n");
printf("-3-Go back to Main Menu\n");
fflush(stdin);
int choice=0;
scanf(" %d", &choice);
if (choice == 1)
{
fflush(stdin);
getFisher(pfisher, i);
i++;
}
if (choice == 2)
{
fflush(stdin);
dispFisher(pfisher, i);
}
else if (choice == 3)
{
break; /* Break out of loop */
}
else
printf("Anything else?\n");
}
/* When this function returns, you get back to the main menu */
}
void getFisher(Fisher* pfisher, int i)
{
char input[buffer];
char* pinput = NULL;
//===============================
printf("Enter Social Security Number: ");
pinput = fgets(input, buffer, stdin);//validate
strcpy((pfisher+i)->SSN, pinput);
//(pfisher+i)->SSN = atoi(pinput);
//==============================
printf("Enter first name: ");
pinput = fgets(input, buffer, stdin);//validates name
strcpy((pfisher+i)->First_Name, pinput);
//==============================
printf("Enter last name: ");
pinput = fgets(input, buffer, stdin);//validates name
strcpy((pfisher+i)->Last_Name, pinput);
//==============================
printf("Enter phone number as a 10 digit number (without any
dashes or spaces): ");
pinput = fgets(input, buffer, stdin);//validate phone
strcpy((pfisher+i)->Phone, pinput);
//(pfisher+i)->Phone = atoi(pinput);
//===============================
printf("Enter email address: ");
pinput = fgets(input, 20, stdin);//validates name
strcpy((pfisher+i)->Email, pinput);
}
void dispFisher(Fisher* pfisher, int i)
{
int len;
int pen;
printf("ssn is equal to: %s\n", ((pfisher+0)->SSN));
printf("First Name is equal to: %s\n", ((pfisher+0)->First_Name));
printf("ssn is equal to: %s\n", ((pfisher+1)->SSN));
printf("First Name is equal to: %s\n", ((pfisher+1)->First_Name));
len = strlen(((pfisher+0)->SSN));
printf("string length = %d\n", len);
pen = strlen(((pfisher+1)->SSN));
printf("string length = %d\n", len);
/*
int arr = 0;
char searchSSN[9];
printf("Enter SSN: ");
scanf("%s", &searchSSN);
for(arr = 0; arr < i; arr++)
{
if(strcmp(&searchSSN, (pfisher+arr)->SSN) == 0)
{
//printf("I is equal to: %s\n", (pfisher+i)->SSN);
printf("Fisher\n");
printf("-------------------------------------------\n");
printf("%d \n %s \n %s \n %s \n %s ", (pfisher + arr)->SSN, ((pfisher+arr)->First_Name), ((pfisher+arr)->Last_Name), ((pfisher+arr)->Phone), (pfisher+arr)->Email);
printf("-------------------------------------------\n");
}
}
*/
}
My output for SSN is getting messed up and becoming "123456789(FirstName string)
example: 123456789TurboTurkey
How can I clean up the length of the string and get in the SSN properly

Answer 1

There is no enough space to store 9 digit in SSN. If you want to store 9 digit in it, its size should be 10 (9 digit + NULL). If there is no NULL charactor, it will read near by locations too..
