Switch !!

[buddydavis]

Hey.... new to VC++...

I need to pass a string to a variable in the Switch statement but it keep giving me errors. Says somethign about conversion. here's what I'm trying to do :

switch (selected)
{
case "This is the launcher":
...
....
.....
break;

case "This is the steamer":
...
....
.....
break;

default :
...
....
.....
break;
}

I want to pass a String into the variable "selected" in the switch function. I just can't seem to get it right.

Thanks.

You're probably confusing the functionality of the switch statements in C with the flexibility of the Select Case statements in VB; the C variant only takes integer numbers.

So is there a workaround for this?

And cases can only be compile-time constants.

Use of strings and floating points in switches may be put into the language soon, though.

Until then, just use if statements.

You could use a string array then use the array index for the switch statement

char *strArray[] = { "String 1", "String 2"};

for (int nLoop = 0; nLoop < sizeof(strArray) / sizeof(strArray[0]); nLoop++);
{
if (strncmp(&strArray[nLoop], strCheck, strlen(strCheck)) break;
}

switch(nLoop)
{
case 0: /* First String */
break;

.....

}

strCheck - The string that you would like to check against.

Use _lfind() in a string array, then switch()

you can also try to do it like this:

enum { This_is_the_launcher, This_is_the_steamer } selected;

void main()
{
	switch (selected) {
	case This_is_the_launcher:
	   .....
	   ...
	   break;
	case This_is_the_steamer:
	   .....
	   ...
	   break;
	default :
	   .....
	   ...
	   break;
	}
}
