Anyone have any idea why this won't run? I've been trying to fix it for hours and can't find the issue. I created a different version utilizing functions from <string.h>, but I'd like to see if it can be built to run without it, while still having the readArray function I've built using getchar

     1  //Structures. Contain members.
     2
     3  #include <stdio.h>
     4
     5  void readArray(char []);
     6
     7  struct Student
     8  {
     9          int id;
    10          char name[30];
    11          float final;
    12  }
    13
    14  main()
    15  {
    16          struct Student st;
    17
    18          printf("Enter student id: ");
    19          scanf("%d", &st.id);
    20          printf("Enter name: ");
    21          readArray(st.name)
    22          printf("Enter final score: ");
    23          scanf("%f", &st.final);
    24
    25          printf("The ID is: %d\n", st.id);
    26          printf("The name is: %s\n", st.name);
    27          printf("The final score was: %.2f\n", st.final);
    28  }
    29
    30  void readArray(char st.name[])
    31  {
    32          char c;
    33          int i;
    34
    35          for(i=0; (c=getchar()) != '\n'; i++)
    36          {
    37          st.name[i] = c;
    38          }
    39          st.name[i] = '\0';
    40  }

THE ERROR:


studentstruc.c: In function âmainâ:
studentstruc.c:22:2: error: expected â;â before âprintfâ
studentstruc.c: At top level:
studentstruc.c:30:23: error: expected â;â, â,â or â)â before â.â token

I realize I just tried to use noko on a text board. oops.

Learn to read.

adding a ; suffix to the call to the readArray function worked... Sorry, I didn't think that you normally needed that for function calls. However I'm still having an error on the function itself, the same one as before.

>>4
Again, learn to read. You can't pass arguments like that.

>>5
Well, mind giving me a pointer on how to pass an argument for the name that would still belong to the Student structure?

>>1 You might want to create struct with malloc

>>6
Read K&R.

>>7
No reason for it. He does need to provide space for the strings themselves in some way, statically or otherwise.

Oh wait, I misread what he was trying to do. Yeah, no reason for malloc at all.

Apart from basic fucking syntax, you should probably ensure your reading loop doesn't run off the end of your array.

Why not use scanf for st.name?

your variable for readArray function is wrong

#include <stdio.h>
void readArray(Student);
struct Student{
    int id;
    char name[30];
    float final;
}
main(){
    struct Student st;
    printf("Enter student id: ");
    scanf("%d", &st.id);
    printf("Enter name: ");
    readArray(st.name)
    printf("Enter final score: ");
    scanf("%f", &st.final);
    printf("The ID is: %d\n", st.id);
    printf("The name is: %s\n", st.name);
    printf("The final score was: %.2f\n", st.final);
}
void readArray(Student st){
   char c;                    
   int i;
   for(i=0;( (c=getchar())!='\n' ) || (i<30); i++){
      st.name[i] = c;
   }   
   st.name[i] = '\0';
}

What's the type of &st.name? What's the type of st? Do you see your error? Because the compiler does.
