Thread: Need some help to fix a declaration syntax error

I am new to programming and am trying to finish this project for my class. not sure where my error is here, can someone help point it out

Code:

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


int displayMenu();
int getData(int * a, int n);
void input();
void display();
float mean1(float[],int);  
float median1(float[],int);  
float mode1(float[],int);  
double standarddeviation1(float array[],int n)


int main()
{
  int com;
  srand(time(NULL));
  do{
     com=displayMenu();
     switch (com)
     {
       case 1 : input(); break;
       case 2 : display(); break;
       case 3 : printf("have a nice day\n");break;
       default : printf("Bad data Try again\n");
      }
      
      }while(com !=3);


return 0;


}




int displayMenu()
{
   int c;
   printf("@@@@@@@@@@@@@@@@@@@@@@@@@@@\n");
   printf("@  1. Enter data          @\n");
   printf("@  2. Display data        @\n");
   printf("@  3. Quit                @\n");
   printf("@@@@@@@@@@@@@@@@@@@@@@@@@@@\n");
   printf("Enter your choice:");
   scanf("%d",&c);
   return c ;
 }
 
 void input()

    {

}

what is an error, are you getting?
I mean, did the code gets compiled without error?

When i ran the compiler I get E2141 declaration syntax error

post your compiler error details, with line no

Error E2141 statistic.c 15: Declaration Syntax error

Refer line no 13, function declaration.
you forget the ;
Note: Please cross check your input function, 'choice' is not initialized.

ok, thanks for the help
