    struct array trouble

    Code:
    #include <stdio.h>
    #include <string.h>
    
    void main()
    {
     struct oz
     {
      char actor[30];
      char character[30];
      int age;
     }
    
     struct oz actor[4];
     int x;
    
     strcpy(actor[0].actor,"Judy Garland");
     strcpy(actor[0].character,"Dorothy");
     actor[0].age=17;
    
     strcpy(actor[1].actor,"Ray Bolger");
     strcpy(actor[1].character,"Scarecrow");
     actor[1].age=35;
    
     strcpy(actor[2].actor,"Bert Lahr");
     strcpy(actor[2].character,"Cowardly Lion");
     actor[2].age = 44;
    
     strcpy(actor[3].actor,"Jack Haley");
     strcpy(actor[3].character,"Tin Woodsman");
     actor[3].age = 40;
    
     puts("Wizard of Oz Database!");
    
     for(x=0;x<4;x++)
     {
      printf("%s played %s, and was %i years old.\n",actor[x].actor, actor[x].character, actor[x].age);
     }
    }
    whenever i compile this, it says ''two or more data types in declaration of 'actor''
    what does this mean? id appreciate if anyone can help.

    could be fussing that your struct has an actor variable and the you declare an oz variable named actor?

    well structs declared outside of main are global so nothing can share its name you can either rename the actor inside of main or rename the actor inside of oz that should fix it.

    and for future reference try not to reuse names so closely together it confuses most people

    I pointed out your mistake above; find it. The warning you get shouldn't really matter even though it's not good design to use the same name for a struct-variable and a struct-member. You're qualifying member actor with the struct-variable actor prefix which is what tells the two apart in usage.

    Are you guys serious?

    Code:
     struct oz
     {
      char actor[30];
      char character[30];
      int age;
     };    // TRAILING SEMICOLON IS REQUIRED
    ...and main's return type should be int, not void.

    i tried changing the actor inside main to both 'person' and 'aaa' and changing the actor inside oz to 'uuu' and it did the same thing. know anything else that could be wrong?

    Replay of your program

    Dear friend,
    You can use.But your codeing is have syntax error.Structre is must ended with };
    in your coding the strcture doesn't ened.
    corrected coding is:
    Code:
    /*Codeing
    Name:SABARINATHAN.S
    PH:09841414918
    DATE:27-02-2006*/
    #include <stdio.h>
    #include <string.h>
    
     struct oz {
      char actor[30];
      char character[30];
      int age;
     };
    main()
    {
    
     struct oz actor[4];
     int x;
    
     strcpy(actor[0].actor,"Judy Garland");
     strcpy(actor[0].character,"Dorothy");
     actor[0].age=17;
    
     strcpy(actor[1].actor,"Ray Bolger");
     strcpy(actor[1].character,"Scarecrow");
     actor[1].age=35;
    
     strcpy(actor[2].actor,"Bert Lahr");
     strcpy(actor[2].character,"Cowardly Lion");
     actor[2].age = 44;
    
     strcpy(actor[3].actor,"Jack Haley");
     strcpy(actor[3].character,"Tin Woodsman");
     actor[3].age = 40;
    
     puts("Wizard of Oz Database!");
    
     for(x=0;x<4;x++)
     {
      printf("%s played %s, and was %i years old.\n",actor[x].actor, actor[x].character, actor[x].age);
     }
    }
    Out Put is:
    Wizard of Oz Database!
    Judy Garland played Dorothy, and was 17 years old.
    Ray Bolger played Scarecrow, and was 35 years old.
    Bert Lahr played Cowardly Lion, and was 44 years old.
    Jack Haley played Tin Woodsman, and was 40 years old.

    main() is int main(), as mentioned, not main() and definitely not void main(). And you should also return something from main(), probably 0.
