As to why it is crashing, that is easy. You are molesting pointers. The problem is, you haven't provided enough information so that any mere mortal (without ability to read your mind) can work out what pointers are being molested.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#define BUFF 120
#define SIZE 9
#define STND 20
#define CLIENTS 50
struct client
{
char firstName[STND];
char lastName[STND];
char ID[STND];
char email[STND];
float funds;
// float wager;
}typedef client;
// FUNCTIONS <<<<<<<<<<<<<>>>>>>>>><<<<<<>>>>><<<>>><<>><<>>><<>><><

char getct(client *,int *);
char checkNameTypeA(char *);
void testdisplay(struct client *pct);

{
client ct[CLIENTS];
client *pct = &ct[0];
int clientCounter = 0;
int *pctcounter = &clientCounter;
menu();
int x = 0;
while(x != 4)

printf("enter selection : ");
scanf("%d", &x);
switch(x)

I would simply like it to accept the info provided in the fields and i still haven't exactly worked out how to store the different instances of the client struct. I suppose a separate array. I started on it but I am lost in my own code at this point... Again sorry for the lack of clarity.
