    Need help reding in struct

    Ok so this is what i have so far... Its about done for what i can see but im having problems when it gets to the reading in gender. Im assuming that i have syntax problems with readin in the name and or age. Please help anything would be nice.

    Sorry about the spacing im sure there was a BB code to fix it... If an Admin or Mod can edit it that would be fine.


    Code:
    #include
    <stdlib.h>
    
    #include
    <stdio.h>
    
    #include
    <string.h>
    
    
    #define
     pause system("pause")
    
    
    typedef
    struct {
    
        
    char yourName[25];
    
        
    int    age;
    
        
    char gender;
    
    } RECORD1;
    
    
    typedef
    struct {
    
        
    char yourName[25];
    
        
    int    age;
    
        
    char gender;
    
    } RECORD2;
    
    
    typedef
    struct {
    
        
    char yourName[25];

    char gender;

    I didn't get a chance to read it all the way through, but from what I see, there is no reason that you should be recreating your RECORD struct since they are all the same.

    Declaring a typedef is not the same as declaring a variable, you are simply creating the contents of your RECORD struct.
    You only need to declare the typedef once, but you can declare as many RECORD variables as you'll need in your program:
    Code:
    typedef struct{
          char *yourName;
          int age;
          char gender;
    } RECORD;
    
    int main (void)
    {
         RECORD teacher, student, banker, tester, gamer;
    
         return 0;
    
    }
    Another thing you should do is since there are more than a couple of choices the user could enter, you'd be better off using a switch statement.
    It'd make your code a lot easier to read and possibly a bit faster

    You think don't I didn't know that? That's not the question I had. The problem was in the %c when reading in a char,
