C programing Switch statement
I am trying to make this code but i can not figure out how to call the functions i made within my switch statements. I have commented somethings out that I can not figure out what to do
Code:
#include <stdio.h>
#include <time.h>
#include <ctype.h>
#include <stdlib.h>
#include <math.h>
#define CARS_ARRAY_SIZE 4
struct cars
{
char name[20];
char make[20];
int car_number;
char color[20];
int distance;
};
int main (void)
{
//declaring variables in array
int i=0;
int AutoOrManual;
int automatic;
int CarType;
int number;
int CarColor;
char DriverName;
int ExitFlag=0;
//opening file for arrayos
FILE *fPointerCars;
srand(time(NULL));//
//Print name and explain this is a racing game
printf("RoseEllen Hoke\n This is a race car game a text base game to race 4 cars across the screen and determine the first second and third place. \n A text file (car.txt) with the name of the driver, type of the race car, car number, and the color of the car is given to you.");
do
{
struct cars AutoManual[CARS_ARRAY_SIZE];
printf("enter 1 if you want race against another user or \n enter 2 if you want to race against 4 cars automatically or \n enter 3 to exit");
scanf("%d",&AutoOrManual);
switch(AutoOrManual)
{
case 1:
// i do not know how to get it to move to the next thing
printf("You have selected Manual");
//CAll Function that runs that type of race
break;

printf("You have selected Automatic");
AutoRace();
break;
case 3:
printf("EXIT");

default:
break;
}
}while(ExitFlag==0)
// return 0;
//}
//i was going to enter another switch statement for manuel mode but i dont see why its uses all the same
//componets as autoomatic i feel like
//int AutoRace()
