Thread: So I'm trying to make menu using do - while

Code:

#include <stdio.h>
#include <stdlib.h>


int main ()
{
    int chicken = 5; int amountOfChicken;
    int fish = 3; int amountOfFish;
    int eggs = 1; int amountOfEggs;
    int fries = 4; int amountOfFries;
    int rice = 1; int amountOfRice;
    int amount;
    char choice; char choice2;


    printf("The Menu is the one below and type 0 to stop.\n");
    printf("[A]Chicken = $5   [B]Fish = $3   [C]Eggs = $1   [D]Fries = $4  [E]Rice = $1\n\n");


    do {




        printf("Enter the letter for the food you want: ");
        scanf(" %c", &choice);
        if (choice == 'A' || choice == 'a') {
            printf("You chose Chicken. How many do you want?\n");
            printf("I want: ");
            scanf(" %d", &amountOfChicken);
            chicken *= amountOfChicken;
            printf("That will be %d", chicken);
            break;
        } else if (choice == 'B' ||choice ==  'b') {
            printf("You chose Fish. How many do you want?\n");
            printf("I want: ");
            scanf(" %d", &amountOfFish);
            fish *= amountOfFish;
            printf("That will be %d", fish);
            break;
        } else if (choice == 'C' ||choice ==  'c') {
            printf("You chose Eggs. How many do you want?\n");
            printf("I want: ");
            scanf(" %d", &amountOfEggs);
            eggs *= amountOfEggs;
            printf("That will be %d", eggs);
            break;
        } else if (choice == 'D' ||choice ==  'd') {
            printf("You chose Fries. How many do you want?\n");
            printf("I want: ");
            scanf(" %d", &amountOfFries);
            fries *= amountOfFries;
            printf("That will be %d", fish);
            break;
        } else if (choice == 'E' ||choice ==  'e') {
            printf("You chose Fish. How many do you want?\n");
            printf("I want: ");
            scanf(" %d", &amountOfRice);
            rice *= amountOfRice;
            printf("That will be %d", rice);
            break;
        } else {
            printf("Error you typed wrong!");
        }
        printf ("Would you like to add more? Y/N \n");
        scanf (" %c", &choice2);


        if (choice2 == 'y' ||choice2 ==  'Y') {
            printf ("Choose which one to add again: \n\n [A]Chicken = $5   [B]Fish = $3   [C]Eggs = $1   [D]Fries = $4  [E]Rice = $1\n\n");
        } else {
            break;
        }
    } while (choice2 != 'N' ||choice2 == 'n');






    return 0;
}

Something is wrong. It doesn't run the way I want it too. When I type 'B' it says "You chose chicken" which is the case 'A' and I don't know why.

It works on my computer. I Type 'B', it's asking for fish.

Avoid the break instruction in your if/else blocks. Break makes you leave the loop.

Code:

#include <stdio.h>
#include <stdlib.h>


int main ()
{
    int chicken = 5; int amountOfChicken;
    int fish = 3; int amountOfFish;
    int eggs = 1; int amountOfEggs;
    int fries = 4; int amountOfFries;
    int rice = 1; int amountOfRice;
    int amount;
    char choice; char choice2;


    printf("The Menu is the one below and type 0 to stop.\n");
    printf("[A]Chicken = $5   [B]Fish = $3   [C]Eggs = $1   [D]Fries = $4  [E]Rice = $1\n\n");


    do {




        printf("Enter the letter for the food you want: ");
        scanf(" %c", &choice);
        if (choice == 'A' || choice == 'a') {
            printf("You chose Chicken. How many do you want?\n");
            printf("I want: ");
            scanf(" %d", &amountOfChicken);
            amountOfChicken *= chicken;
            printf("That will be %d\n\n", amountOfChicken);


        } else if (choice == 'B' ||choice ==  'b') {
            printf("You chose Fish. How many do you want?\n");
            printf("I want: ");
            scanf(" %d", &amountOfFish);
            amountOfFish *= fish;
            printf("That will be %d\n\n", amountOfFish);


        } else if (choice == 'C' ||choice ==  'c') {
            printf("You chose Eggs. How many do you want?\n");
            printf("I want: ");
            scanf(" %d", &amountOfEggs);
            amountOfEggs *= eggs;
            printf("That will be %d\n\n", amountOfEggs);


        } else if (choice == 'D' ||choice ==  'd') {
            printf("You chose Fries. How many do you want?\n");
            printf("I want: ");
            scanf(" %d", &amountOfFries);
            amountOfFries *= fries;
            printf("That will be %d\n\n", fish);


        } else if (choice == 'E' ||choice ==  'e') {
            printf("You chose Rice. How many do you want?\n");
            printf("I want: ");
            scanf(" %d", &amountOfRice);
            amountOfRice *= rice;
            printf("That will be %d\n\n", amountOfRice);


        } else {
            printf("Error you typed wrong!\n\n");
            break;
        }
        if (choice == 'A' || choice == 'a' || choice == 'B' || choice == 'b' || choice == 'C' || choice == 'c' || choice == 'D' || choice == 'd' || choice == 'E' || choice == 'e') {
        printf ("Would you like to add more? Y/N\n");
        scanf (" %c", &choice2);
        }


        if (choice2 == 'y' ||choice2 ==  'Y') {
            printf ("Choose which one to add again: \n\n [A]Chicken = $5   [B]Fish = $3   [C]Eggs = $1   [D]Fries = $4  [E]Rice = $1\n\n");
        } else {
            break;
        }
    } while (choice2 != 'N' ||choice2 == 'n');
    if (choice == 'A' || choice == 'a' || choice == 'B' || choice == 'b' || choice == 'C' || choice == 'c' || choice == 'D' || choice == 'd' || choice == 'E' || choice == 'e') {
    amount = amountOfChicken + amountOfEggs + amountOfFish + amountOfFries + amountOfRice;
    printf ("The total is: $%d", amount);
    }




    return 0;
}

Okay this is my updated code. Now my problem is the amount and thanks Shadew. So that's why it terminates always. XD

Oh nevermind the problem is the variables amountOfChicken and other ........s like that it should be :

Code:

int amountOfChicken = 0;

I should assign them the value 0 XD okay my bad as newbie.
