Question

int NameExist(queue **wait, char *name)

{

queue *Restaurant = *wait;

while( Restaurant == NULL) {

switch(Restaurant)

{

  case 1: return 0;

          break;

  case 2: (strcmp(Restaurant->name, name)==0);

          return 1;

         Restaurant = Restaurant->Next;

          break;

}

return 0;

}

}

I get this error for this function -error: switch quantity not an integer
switch(Restaurant)
^~~~~~~~~~

boolean update(queue **wait, char* name)

{

    queue *Restaurant = *wait;

    // if there is no order yet

    while(Restaurant == NULL) {

        return FALSE;

    }

    

    while(Restaurant != NULL) {

        switch (strcmp(Restaurant->name, name) == 0) {

            case 1: if(Restaurant->Status == Time) {

                return FALSE;

                break;

            }

          case 2: Restaurant->Status = Time;

                if(debugMode == TRUE) {

                    printf("DebuggingMode \n");

                    displayListInformation(wait);

                    

                }

                return TRUE;

            }

        }

}

I get getting a warning message for this function.  warning: switch condition has boolean value [-Wswitch-bool]
switch (strcmp(Restaurant->name, name) == 0) {
^~~~~~

void displayList(queue **wait)

{

        queue *Restaurant = *wait;

while(Restaurant != NULL) {

    

    switch(Restaurant->Status == Time) {

        case 1:  printf("Wait \n");

            break;

                case 2: printf("Calling ahead\n");

                Restaurant = Restaurant->Next;

        }   

         return;

        }            

}

also get the same warning for this function-  warning: switch condition has boolean value [-Wswitch-bool]
switch(Restaurant->Status == Time) {
^~~~~~

Please help I'm not sure if I can write these another way to fix them. any help will be highly appreciated.

PLEASE GIVE IT A THUMBS UP

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

int NameExist(queue **wait, char *name)

{
queue *Restaurant = *wait;
while (Restaurant == NULL)
{
switch ((int)Restaurant)
{
case 1:
return 0;
break;
case 2:
(strcmp(Restaurant->name, name) == 0);
return 1;
Restaurant = Restaurant->Next;
break;
}
return 0;
}
}

// In this the switch statement value is of type 'queue' and in case the case 1,
// where 1 is integer, then in that case just change type of case, as I have done.

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

boolean update(queue **wait, char *name)
{
queue *Restaurant = *wait;
while (Restaurant == NULL)
{
return FALSE;
}

while (Restaurant != NULL)
{
if (strcmp(Restaurant->name, name) == 0)
{
if (Restaurant->Status == Time)
{
return FALSE;
break;
}
}
else{
Restaurant->Status = Time;
if (debugMode == TRUE)
{
printf("DebuggingMode \n");
displayListInformation(wait);
}
return TRUE;
}
}
}

// In this you are using swtich for TRUE and FALSE, and it is advisable to
// use IF-ELSE for boolean, that's why it was giving warning, I have converted switch to if

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

void displayList(queue **wait)
{
queue *Restaurant = *wait;
while (Restaurant != NULL)
{
if (Restaurant->Status == Time)
{
printf("Wait \n");
}
else
{
printf("Calling ahead\n");
Restaurant = Restaurant->Next;
}
return;
}
}

// Here also the same problem was there

There is no output, as I wasn't having the whole code.
