    Assigning a value to struct variables?

    Hi guys, I'm trying to assign a value to the variables in my struct using the statement:

    fscanf(fp, "%s%10s%9s%s", acct.name, acct.num, acct.pin, strbal)

    but when I try to access them, it looks like the variables (acct.name, acct.num, acct.pin) are all empty. Also, can someone point me to a good reference material (that is not too hard to understand, if you know what I mean) that has basic examples? Thanks.

    Code:
    #include <stdio.h>
    #include <stdlib.h>
    
    #define MAXAMT 999999.99
    
    typedef struct Account{
    	char name[60];
    	char num[20];
    	char pin[10];
    	float bal;
    } Account;
    
    Account acct;
    
    ...
    
    void loadAcct(){
    	char strbal[20];
    	
    	FILE *fp;
    	
    	fp = fopen("/acctinfo.txt", "r+");
    	
    	if (fp != NULL) {
    		while(4 == fscanf(fp, "%s%10s%9s%s", acct.name, acct.num, acct.pin, strbal)) {
    			acct.bal = atof(strbal);
    			printf("%s\n%s\n%s\n%f\n", acct.name, acct.num, acct.pin, acct.bal);
    		}
    	} else {
    		printf("Account info not found.");
    	}
    
    	fclose(fp);
    	getch();
    }
