Yes, just looked it up in my C "white book".
Break will exit the innermost do, while or for loop.
*****
Break will also exit "switch" selective structures:
Code:
switch (c)
{
case 1: puts("One.");
case 2: puts("Two.");
}
If c equals 1 it will print
We need to add the break instruction:
Code:
switch(c)
{
case 1:
puts("One.");
break;
case 2:
puts("Two.");
}
You may ask yourself... What's the use of this? Easy. In QB you can do:
Code:
CASE 1,2,3,7: PRINT "one, two, three, or seven"
But you can't do it in C. Instead you write:
Code:
case 1:
case 2:
case 3:
case 7:
puts("one, two, three, or seven");
IMHO, it is more flexible than QB's approach. Look at this code which gives some info about numbers from 0 to 9:
Code:
case 3:
case 5:
case 7:
puts("It is prime");
case 2:
puts("It is even");
break;
default:
puts("Not prime.");
The QB translation is trickier:
Code:
CASE 2: PRINT "It is prime.":PRINT "It is even."
CASE 3,5,7: PRINT "It is prime."
CASE ELSE: PRINT "Not prime."
Which looks strange (imagine that you have MORE code than a single PRINT).
Under Turbo-C, there is a GOTO statement. You can jump out loops with it too.
Do you want the "big - flames - thread" back in da new forum?
Quote:goto is evil.
Nah, goto is cool.
Code:
$ cd /usr/src/linux-2.4
$ grep -r "goto" * | wc -l
14830
setjmp and longjmp are evil.
