Maximum of two numbers by switch case code

Question

Can someone please help me with a code to get a maximum of two numbers using a switch case code. I have been trying today and ended up using the following ;

switch (number1 >number2)
case 1:
//codes
case 0:
//codes
Although it runs it keeps warning me that the switch condition contains boolean value

Answer 1

Hm.

You can always explicitly convert it:

(int)(n1>n2)

That should normally get rid of the warning.

Answer 2

HonFu these last two solutions worked. Thanks

Answer 3

Did you really do this in C and not in C++?

I don't get a boolean warning, and I also didn't expect one either, since in C such an expression should be converted to 1 or 0 simply.

Maybe you should show us the actual code (this one wouldn't even run as it is written).

Answer 4

I did this in C en the actual... the warning is given by the compiler

Answer 5

Actual code..
int main (void)
{int num1, num2;
printf ("Enter two numbers:") ;
scanf ("%d%d", &num1, &num2) ;

if (num1!=num2)
{switch (num1 >num2)
{case 1:
printf ("%d is greater than %d. \n", num1, num2);
break ;

case 0:
printf ("%d is greater than %d.", num2, num1) ;
break;}
}

else
printf ("%d is equal to %d.", num1, num2) ;

return 0;
}

Answer 6

Converting switch (int) (num1 >num2) does not work

Sorry it worked I wrote switch (int) (num1>num2)
instead of switch ((int) num1 >num2)

Answer 7

When I have a problem like this, I try a minimalistic code snippet that expresses the shape I'm struggling with.

switch(3>4) {
case 1: printf("yep"); break;
case 0: printf("nope"); break;
}

If I run this here, it runs without problems.

And if I run this:

switch((int)3>4) {
case 1: printf("yep"); break;
case 0: printf("nope"); break;
}

It still works.

Can you try these in your environment and see if it works?

import java.util.Scanner;
class Switch{
public static void main(String[] args)
{
Scanner sc=new Scanner(System.in);
System.out.println("enter a integer");
int a=sc.nextInt();
System.out.println("enter a integer");
int b=sc.nextInt();
int c=(a>b)?1:0;
switch(c)
{
case 1:
System.out.println("a is greater");
break;
case 0:
System.out.println("b is greater");
break;
default:
System.out.println("invalid");
break;
}
}
}
