Thread: Simple OR question

Hi

I was wondering if this is appropriate use of the OR operand. I know there are lots of different types of or, but i'm just looking for the program to print if one or the other of the statements is true.

Thanks

Code:

#include <stdio.h>


int main(int argc, const char * argv[])
{
// insert code here...

int a; //example numbers!
    int b;
    int c;
    int d;
    a=1;
    b=2;
    c=3;
    d=4;


    if ( ( a < b ) OR ( c<d ) )
    {
        printf("Yes");
    }
    return 0;
}

Also, i'm getting a build error expecting a ) on the if line. I can add a ) even though i don't see why it would expect one but it still asks for ).

Thanks

The OR operator is written like this:

Code:

if(a < b || c < d)
{
    ....
}

AND is &&.

There are a few operators you can write like text, but nobody does that.

This is OK, furthermore if you like, you can use whatever operator name you want (almost) :

Code:

#define OPERATOR_OR ||
#define O_R ||

if (x OPERATOR_OR y)
{
    // do something
}

if (x O_R y)
{
   // do something
}

@winuser,
Please don't post the random ramblings of your inexperience. It's a waste of everybody's time.

@superfish151,
Some international keyboards don't have the characters used in the logical and bitwise operators, having replaced them with more generally useful characters for their language. So since 1995 C provides the iso646.h header with macros for alternate spellings for those operators. They are built into C++ as keywords (although apparently MS C++ compilers require the header). In general, though, they shouldn't be used unless you're actually working with such a keyboard.
