The program below doesn't let the user to enter the student's name. Originally, I used scanf() instead of fgets() to store the input since scanf() doesn't store spaces. (Original program here)
I have tried the solution suggested here but using scanf("%d *[^\n]", &option); in menu() doesn't seem to work for me. Could it be the ID number generator part which is causing this problem?
#include <stdio.h>
#include <conio.h>
#include <stdlib.h>
#include <string.h>
#define MAX 200
#define ID_SIZE 20
#define NAME_SIZE 50
#define ADDRESS_SIZE 80
#define TEL_SIZE 15
int i = 0;
int total = 0;
int result;
char ID[ID_SIZE];
int menu();
int add_ID();
...
struct Student{
char stud_ID[ID_SIZE];
char name[NAME_SIZE];
char address[ADDRESS_SIZE];
char tel_no[TEL_SIZE];
float marks;
} stud [MAX];
int main() {
menu();
getch();
return 0;
}
int menu() {
int option;
printf ("1. Insert new student\n\n");
printf ("2. Search for a particular student by ID number\n\n");
...
printf ("Please enter your option: ");
scanf ("%d", &option);
while ((option < 1 ) || (option > 6)){
printf("Please reenter your option: ");
scanf ("%d", &option);
}
switch (option) {
case 1 : add_ID();
break;
case 2 : search_ID();
break;
...
case 6 : printf("Exit\n");
exit(0);
break;
getch();
break;
}
return 0;
}
int add_ID () {
char next;
printf("\n>> Add new student <<\n\n");
do {
sprintf(ID, "%d", i+1);
strcpy(stud[i].stud_ID, ID);
printf("Student ID: %s\n", stud[i].stud_ID);
printf("Enter Name: ");
fgets(stud[i].name, NAME_SIZE, stdin) ;
printf("Enter address: ");
fgets(stud[i].address, ADDRESS_SIZE, stdin) ;
printf("Enter telephone number: ");
fgets(stud[i].tel_no, TEL_SIZE, stdin) ;
printf("Enter marks: ");
scanf("%f", &stud[i].marks);
printf("Do you want to add another student? (y/n):\n");
scanf("%s", &next);
i++;
total = i;
} while (((next == 'y') || (next == 'Y')) && (i < MAX));
if ((next == 'n') || (next == 'N')){
printf("Total students: %d\n\n", total);
menu();
getch();
}
return 0;
}
int search_ID() {
printf("\n>> Search for student using ID <<\n\n");
printf("Please enter the student ID: ");
scanf("%s", ID);
display_Header();
for (i = 0; i < total; i++) {
result = strcmp(stud[i].stud_ID, ID);
if (result == 0){
display_Info(i);
break;
}
}
if (i == total) {
printf ("Not found\n");
}
menu();
getch();
return 0;
}
...
The following is the output of the program after option 1 is selected:
Student ID: 1
Enter name: Enter address:
The program doesn't wait for keyboard input and immediately execute the subsequent statement.
