    Can anyone explain why this simple trivia game is not working?

    Code:
    #include <stdlib.h>
    #include <stdio.h>
    #include <time.h>
    #include <ctype.h>
    
    
    //Trivia Game
    
    
    //Function Prototypes
    int people(void);
    int places(void);
    void pause(int);
    
    
    //Global Variables
    int answer=0;
    
    
    //Main
    
    
    main()
    {
    
    
      do
      {
          system("clear");
        printf("\t\tTrivia Game\n");
        printf("\tEnter a Choice:\n");
        printf("1.People");
        printf("2.Places");
        printf("3.Quit");
        scanf("%d",answer);
        switch(answer)
        {
            case 1:
            if (people()==2)
            printf("\nCorrect\n");
            else
            printf("\nIncorrect\n");
            pause(2);
            break;
    
    
            case 2:
            if (places()==2)
            printf("Correct\n");
            else
            printf("Incorrect\n");
            pause(2);
            break;
        }
    while (answer!=3);
      }
    }
    
    
    int places(void){
        int choice=0;
        printf("What place is warmer?\n");
        printf("1.Alaska\n");
        printf("2.Hawaii\n");
        printf("Pick Your Choice!\n");
        scanf("%d",&choice);
        pause(2);
        return choice;
    }
    
    
    int people(void)
    {
        int choice=0;
        printf("What person was president?\n");
        printf("1.Hilary Clinton");
        printf("2.Bill Clinton");
        scanf("%d",&choice);
        pause(2);
        return choice;
        }
    
    
    void pause(int inNum)
    {
        int iCurrentTime=0;
        int iElapsedTime=0;
        iCurrentTime=time(NULL);
        do
        {
            iElapsedTime = time(NULL);
        }
        while
        ((iElapsedTime-iCurrentTime)<inNum);
    }

    You are going to be more specific than "not working"

    What is it doing? What would you like it to do?

    First thing that jumps out at me:

    main() should be "int main (void)" and you should have a return statement at the end of main.

    also:

    scanf("%d", &answer);

    you forgot the &

    It doesn't work, because it doesn't compile.

    $ gcc -Wall foo.c
    foo.c:23:1: warning: return type defaults to ‘int’ [-Wreturn-type]
    foo.c: In function ‘main’:
    foo.c:35:5: warning: format ‘%d’ expects argument of type ‘int *’, but argument 2 has type ‘int’ [-Wformat]
    foo.c:57:1: error: expected ‘while’ before ‘}’ token
    foo.c:95:1: error: expected declaration or statement at end of input
    foo.c:95:1: warning: control reaches end of non-void function [-Wreturn-type]

    You have a mis-placed brace, and a broken scanf to fix.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    So far, PEBKAC.
    Start over and explain the problem.

    Just add "&" to scanf statement as mentioned before..., and add return statement to main function.. Thats it.. Here's the output
