HELP IT KEEPS GIVING ME SAME ERRORS

[RichardLim]

I am a newbie in programming and I'm using visual studio.
i typed in this

#include <stdio.h>
#include <conio.h>
#define PI 3.1416 

void main(void)
{                               

float radius, circumference, area;

radius = 2.5;

circumference = 2 * PI * radius;

area = PI * radius * radius;

printf("radius of a circle = %f cm\n", radius);
printf("circumference = %f cm\n", circumference); 
   printf("Area = %f sq cm\n", area);  
   getch();
} 

it gives me

What is wrong with it?

I'm not sure if visual studio supports a deprecated library like conio.h and it's functions like getch(), try removing them

also use int main instead of void main

[Shardendu]

do the following changes :

void main(void) to int main()

remove getch(), use header file "stdlib.h" and use system("pause") at place of getch()
It will hold the screen for you. (same as getch();)

use return 0 for returning nothing(same as void) in the end of the program.
return 0; is necessary because you are using an integer return type main function.

sorry for bad format reply...but i hope it will help :)

This syntax error below tells me that you have only an open brace somewhere in your code. That is, there is no corresponding closing brace. But yet I do not see this error condition in your posted code. Are you sure you posted the faulty code?

I can only assume this second syntax error is related to the missing closing bracket.

How about posting the faulty tryagain.c code?
