Answer 1

char id_c[30], name_c[30];
int age;
NSString *id_c, *name_c;
Student *student;
file = fopen("Student.txt", "r");
while (!feof(file)) {
    fscanf(file, "%s %s %d ", id_c, name_c, &age);
    id = [NSString stringWithUTF8String:id_c];
    name = [NSString stringWithUTF8String:name_c];
    student = [[Student alloc] initWithId:id Name:name Age:age];
    [student print];
}

Answer 2

Use NSFileHandle to find a file, then use NSData to read the entire text content, then use NSData to convert NSData to NSString, and then use 'n' to separate the nsstring into an NSAarray, so that you can loop through it.
