Strange error I have not gotten before.

[tameeyore]

I am getting the following error when I compile my program on gcc. two or more data types in declaration of `main'
Also I want to print out the structure in one of my cases but won't let me call the structure and I don't understand. Please help.. I am new to this programming.


Here is the code.

   #include <stdio.h>
   #include <stdlib.h>

   int  num_comp;
   float  num_months;

   struct company{
      char city[30];
      float months[10];
      char name[20];
      char manager[20];
    }

   int main(int argc, char **argv){

       FILE *fp;
       struct company;
       char filename[20];
       int month,choice;

       printf("Please enter the name of the relevant file:  ");
       scanf("%c", filename);
       fp = fopen(filename, "r");
 
      printf("Please enter your choice:" );
       printf("1. Enter 1 to get the statistics for a specific month.");
       printf("2. Enter 2 to get the overall statistics.");
       printf("3. Enter 0 to terminate the program.");


       switch(choice){
          case 0:
          printf("Good Bye!");
          break;
          case 1:
          printf("Which month are you interested in? ");
          scanf("%d", month);
          break;
          case 2:
          printf("The statistcs are below: %s\n");
          break;
          default:
           break;
         }
      return 0;
}

Your struct is missing a final ;

[tameeyore]

What is a final? please advise.

[itsme86]

You're missing a semi-colon at the end of your structure (line 12).

Also:

printf("The statistcs are below: %s\n");

You're telling printf() to print a string but you're not telling it which string to print.

EDIT: Also:

scanf("%c", filename);

You really want a string, but you're telling scanf() to read in a single char.

EDIT 2: Also:

scanf("%d", month);

This is incorrect. You need to pass pointers to scanf() for it to store things properly.
