Programming menu options

Code:

---

int main(){

                int ans;
               
                //Get user's input
                printmenu();
                scanf("%d", &ans);

                while (ans !=6) {
                       
                        if (ans==1)
                                tripfueleff();
                        else if (ans==2)
                                getitem();
                        else if (ans==3)
                                printlogo();
                        else if (ans==4)
                                multgame();
                        else if (ans==5)
                                printfuelgraph();
                       
                }
}
               
//Prints out menu
void printmenu() {
        printf("Which of the following options would you like?\n");
        printf("1) Calculate fuel efficiency for a trip.\n");
        printf("2) Determine whether or not to go back home and pick up an item.\n");
        printf("3) Print the car logo to the display.\n");
        printf("4) Play the multiplication game.\n");
        printf("5) Print a visual display of the recent fuel efficiency.\n");
        printf("6) Quit\n");
}

That's what I got for a menu so far. But after I choose an option, and the specified function runs, it repeats the function. After the function is done running I need it to go back to the menu instead of repeating. Do I need to add something to the while statement to do this or something to the functions themselves?

Here's an example of one of the functions:

Code:

---

void getitem() {
        int mins_dist, mins_before, mins_forgot, total, spare1, spare2;
       
        //User input
       
        printf("How long does it take you to drive to work (in minutes)?\n");
        scanf("%d", &mins_dist);
       
        printf("How many minutes before work did you start?\n");
        scanf("%d", &mins_before);
       
        printf("How many minutes did it take you to realize you forgot an item?\n");
        scanf("%d", &mins_forgot);
       
        //Determine if you should turn around
       
        total = (mins_forgot * 2) + mins_dist;
        spare1 = mins_before - total;
        spare2 = mins_before - mins_dist;
       
        if (total <= mins_before)
                printf("Go back home and pick up the item.\nYou will arrive at work with %d minutes to spare.\n", spare1);
        else
                printf("Just go to work, you'll have to do without the item.\nYou will arrive at work with %d minutes to spare.\n", spare2);
}

You should move your printmenu() and scanf() calls inside your while loop.
You may also find that do...while is a better loop structure in this case.

Perfect! That was exactly what I need thank you. And i'll definitely look into a do while.
