Ive been given an assignment and have finish setting up the information and now I cant get it to run. Ive looked at the code several times and still cant find the problem. Could anyone find what the problem is so i can get this thing to work and hand it in before its too late?

Code:#include<stdio.h> #include<math.h> int options(); int time_to_swap(); int get_hypote(); int get_sine_form(); int get_euclids (int argc, const char * argv[]); int mid_point(); #define PI 3.14159265 int main() { int four; //fourth function int second; char choice; //option to end program int begin; int temp; int five; int third; begin = options(); do{ second = mid_point(); //finds midpoint third = time_to_swap(); //swaps four = get_hypote(); //find hypotenuse five = get_sine_form(); //calculates sine of a number temp = get_euclids (int argc, const char * argv[]); //find the GCD printf("\n To end this program please enter the letter 'n'.\n"); scanf("%c",&choice); getchar(); }while(choice != 'n'); } int options() //prints out what the overall program will do { printf("Throughout the program it will perform the following: \n"); printf("1.
