(structure+array+pointer)to make a simple database
Hi,guys!!now i wish to make a program that can intput data into the array of structure......firstly, i can input the data and then print it at once,but when i come back to the choice function,it seems can't print more a record ,hope some people can help me !!
I have attached the file named by a2obackup.c
/***The program is under below***/
#include<stdio.h>
#define SIZE 10 /*The number of record is 10*/
struct name{
char first[30];
char last[30];
};
struct datehire{
char day[2];
char month[2];
char year[4];
};
struct employee{
struct name allname;
char id[20];
char salary[20];
struct datehire alldate;
};
typedef struct employee Employee;
void choice();
void addrecord(Employee *);
void changerecord(Employee *);
void loada(Employee *);
void loadall(Employee *);
main(void){
choice();
return 0;
}
void choice(){ /*choice function that used to led the user to choice the function*/
Employee employee_list[SIZE];
int choice;
int rubbish;
do{
printf(" <--------Welcome to employee database system--------> \n\n");
printf(" Please choose the number of function that you want->\n\n");
printf(" <1>Add Record/Records\n");
printf(" <2>Change a Record\n");
printf(" <3>Load A record to screen\n");
printf(" <4>Load ALL record to screen\n");
printf(" <5>Exit\n");
