Mutli Switch statement help

i m trying to code a case within a case in a switch statement if thats possible
but i keep getting all result and if i put a break within them it will only show first statement only

Code:

---

#include <stdio.h>
int question_him(char *question)
{
    int result;
    puts(question);
    scanf("%d",&result);
    return result;
}
char *returner(char *returner)
{
    return returner;
}
int main(void)
{
    int result;
    char *buffer;
    for(;;) {
        result=ask_it("Hello here is your menu\n"
                      "1)FILE functions\n");
        switch(result)
        {
            case 1:
                result=ask_it("Youve choosen FILE functions\n"
                              "1) write it down\n"
                              "2) read it\n"
                              "3) append it\n");
            case 'w':
                puts("write it down\n");
                buffer=returner("Youve choosen write it down option");
            case 'r':
                puts("you have choosen read it option \n");
                buffer=returner("Youve choosen read it option");
            case 'a':
                puts("You have choosen append it\n");
                buffer=returner("Youve choosen append it option\n");
                break;
        }
        break;
    }
    puts(buffer);
    return 0;
}

You're not explaining what you actually want, or rather, your code doesn't match up with what you're implying you want. Anyway...

Code:

---

while( choice != 'N' && choice != 'n' )
{
switch( (choice = getchoice()) )
{
    case 'Y': case 'y':
    {
        printf( "You made your choice, now live with it.\n" );
        while( choice2 != 'o' )
        {
            switch( (choice2 = getchoice()) )
            {
                case 'x':
                    printf( "You die.\n" );
                    choice = 'n'; /* make it drop from the outer loop too... */
                break;
                default: /* whatever */ break;
            }
        }
    }
    break;

    default: /* do nothing */ break;
}

I don't know what it is you're trying to do, but you can pretty much nest anything (not functions) if you have enough braces. ;)

i tried but program crashed

Code:

---

#include <stdio.h>
int ask_it(char *question)
{
    int result;
    puts(question);
    scanf("%d",&result);
    return result;
}
char *func(char *lol)
{
    return lol;
}
int main(void)
{
    int result;
    char *buffer;
    for(;;) {
        result=ask_it("Hello here is your menu\n"
                      "1)FILE functions\n");
        switch(result)
        {
            case 1:
                result=ask_it("Youve choosen FILE functions\n"
                              "1) write it down\n"
                              "2) read it\n"
                              "3) append it\n");
                switch(result){
                    case 'w':
                          puts("Youve choosen write it down");
                          buffer=func("Youve choosen write it down");
                          break;
                    case 'r':
                          puts("Youve choosen read it option");
                          buffer=func("Youve chossen read it option");
                          break;
                    case 'a':
                          puts("Youve choosen append it option");
                          buffer=func("youve choosen append it option");
                          break;
                }
        }
        break;
    }
    puts(buffer);
    return 0;
}

it crashed i think because buffer doesnt got anything but why shouldnt that statement scanf result then reswitch the statement again ?

I've modified your code. It'll work fine.
In your function you were reading the cases as 1,2,3 while you were taking the case labels to be 'w','r','a'.

i thought i can casted it inside the switch

He means this:

Code:

---

                result=ask_it("Youve choosen FILE functions\n"
                              "1) write it down\n"
                              "2) read it\n"
                              "3) append it\n");
                switch(result){
                    case 'w':

---

Why ask them to enter 1 if you are going to check for W?


Quzah.

anyways i fixed it

Code:

---

#include <stdio.h>
int ask_it(int bol,char *question)
{
    int result;
    puts(question);
    scanf("%d",&result);
    if(bol){
        scanf("%c",&result);
        return (char)result;
        }
    return result;
}
char *func(char *lol)
{
    return lol;
}
int main(void)
{
    int result;
    char *buffer;
    for(;;) {
        result=ask_it(0,"Hello here is your menu\n"
                      "1)FILE functions\n");
        switch(result)
        {
            case 1:
                result=ask_it(1,"Youve choosen FILE functions\n"
                              "1) write it down\n"
                              "2) read it\n"
                              "3) append it\n");
                switch(result){
                    case 'w':
                          puts("Youve choosen write it down");
                          buffer=func("Youve choosen write it down");
                          break;
                    case 'r':
                          puts("Youve choosen read it option");
                          buffer=func("Youve chossen read it option");
                          break;
                    case 'a':
                          puts("Youve choosen append it option");
                          buffer=func("youve choosen append it option");
                          break;
                    default:
                            puts("Sorry I dont understand your choice please retry :P");
                            continue;
                }
        }
        break;
    }
    puts(buffer);
    return 0;
}

oh yah that was misspelling in writing stupid me lol

anyway thanks alot for the help mate

It is OFTEN a good idea to split nested switch statements into their own functions - that way, it's easier to follow the code, and it's much less likely to get the overall switch enormous. There are times when this is NOT a good plan, but that's the exception rather than the rule.
