Help with IF statements

**boontune** · 01-22-2003

Is it possible to use the IF statement over several lines?

Because i have quite afew conditions that have to be met in order
to continue my program.....

And if i put them all in it stretches right across the screen.

Thanks

More like:

Code:

if (  Condition
   || Condition
   || Condition )
{
  /* Something here */
}

You can do this with anything, as long as there's no ';' it assumes
the line is not finished yet and move's on to the next line.

A big argument list for example.

Code:

void blab(int a,int b,int c,int d,int e,int i,int f,int g,int z,int x,
                int r,int y);

You can also do this with a string (use the \ character to separate the string):

Code:

int main(void)
{
   char a[] = "Hello " \
         "worl" \
         "d!";

   printf("%s\n", a);
   return 0;
}

Code:

// This can be done
if(condition1)
{
      statement1;
}
else if(condition2)
{
      statement2;
}
else 
{
      statement3;
}

// This also can be done
if(condition1)
{
      if(condition2)
      {
           if(condition3)
           {
                statement1;
                statement2;
                ..................
            }
      }
}

The way i understand it he has many conditions for his IF
statement, therefore they don't all fit on 1 line, si he'd like
to know if he could go on the next line with conditions.
Answer is sure.

Yeah sorry,

I mean in the header file ctype.h, there are functions you can use to check conditions, ie.

isdigit() - to check numbers
isalpha() - for letters

I need to know what the one for punctuation is?

**adrianxw** · 01-22-2003

... and in your crossposted thread, I told you to open your ctype.h file and look! You will find what you want, and a load of other stuff.

You could code a function on your own if the one you are searching is not existing

Code:

bool ispunctuation(char ch)
{
     return (ch == '\''); // since ' (quote / punctuation) has a special meaning, we need to use the a quote then a slash (backward) then a quote then another quote
}
