Newbie- having trouble with functions
:confused: Can anyone help a rookie new to C who is working hard to figure out and get comfortable with functions?? Below is my code for a program that is to prompt user for input to draw a shape by invoking the corresponding function. Right now I cannot get it to compile. I am getting an error "C:\Documents and Settings\Owner\My Documents\project2.c(70) : error C2143: syntax error : missing ';' before 'type' " [reference line is: int circle (int shape) ].
Could someone please take a look at my code? I am still working to understand functions and even all the concepts of C. I have not been able to locate the source of the error and am also afraid even if I can that I may have used incorrect data types, called the functions incorrectly, etc. Any and all suggestions and assistance would be appreciated. Thanks,
Code:
/*This program will draw a shape based on a value entered*/
/*by the user until the sentinel value is entered to terminate*/
/* the program. */
#include <stdio.h>
int circle (int shape);
int triangle(int shape);
int rectangle (int shape);
int line(int shape);
int main()
{
int shape=0; /* Initialize variable */
printf("This program will draw a shape on your screen based on \n"); /*Prompt user for correct input*/
printf("your selection from the following menu: \n \n");
printf("1. Draw a circle. \n");
printf("2. Draw a triangle. \n");
printf("3. Draw a rectangle. \n");
printf("4. Print one blank line. \n");
printf("5. Exit program.\n \n");
printf("Enter your choice: \n");
scanf("%d", &shape); /* Read value user enters from keyboard */
fflush(stdin);
while (shape != 5) { /*While loop to continue program until sentinel value is entered*/

printf("This program will draw a shape on your screen based on \n"); /*Prompt user for correct input*/
