Question

What's wrong with my code? i keep getting the following errors:

Warning: static decleartion of fibonacci follows non-static decleartion
warning: previous decleartion of fibonacci was here
error: "int_max" undeclared (first use in this function)
warning: static ddecleation of reverse follows non-static decleartion
warning: previous declartion of reverse was here
warning: no newline at end of file
error: syntax error at end of input

I'm supposed to create a menu driven system using function pointers. I dont know what i'm diong wrong. Once i create teh menu, the user selects an input and runs one of four programs.


Here is my code:


#include<stdio.h>
#include <string.h>

void dice(); /* module for program 1 */
void series(); /* module for program 2 */
void reverse(); /* module for program 3 */
void patterns(); /* module for program 4 */

int main()
{
int program;/*declare variables */

printf("What whould you like to do? 1 - Simulate the roll of twodice "); /*prompt one*/

printf("2 - The Fibonacci Series "); /*prompt 2*/

printf("3 - Reverse Digits "); /* prompt 3*/

printf("4 - Print Four Patterns "); /*prompt 4*/

printf("5 - Exit "); /*exit choice */

scanf("%d",&program); /* reads user input and stores into variable program */

while(program!=5) /* loop that decides what to do */
{
switch(program)
{
case 1: dice(); /*initiates program 1 */
break;

break;
case 3: reverse(); /*initiates program 3*/

break;

}
printf("What whould you like to do? 1 - Simulate the roll of twodice ");
printf("2 - The Fibonacci Series "); /* allows user to reinput choice */
printf("3 - Reverse Digits ");
printf("4 - Print Four Patterns ");
printf("5 - Exit ");
scanf("%d",&program);
}
printf("GOOD BYE!"); /*if input is 5, gives goodbye message and exits */

return 0;

Dice is supposed to simulate the rolling of a dice. I believe that is correct.
Series is a fibonacci series program where the user inputs what number they'd like in the series. the program that outputs the fibonacci number and the highest number the computer can process in the series. Patteerns is a program that creates four triangles of different pattern that the user decides how large the triangle is. Reverse is a program that allows the user to input a number and then the program reverses that number.

Can someone review my code and correct it so that it will work. Can you also tell me what i did wrong and explain to me why it is wrong? thank!
