Compound Statement

(what will be the output someone please help me out thanks)


if (abs(x) < xmin) x = (x > 0) ? xmin : -xmin;

If you indent it, the truth will be revealed!

Code:

if (abs(x) < xmin)
   x = (x > 0) ? xmin : -xmin;

The first line of code is simple.
The second line of code says.
If x>0, then assing xmin to x.
If condition x>0 is false (thus x <= 0 is true ) , then assign -xmin to x.

In other (code) words

Code:

if (abs(x) < xmin)
{
     if(x > 0)
     {
            x = xmin;
     }
     else 
     {
            x = -xmin;
      }
}

Hope this helps

hey thanks dear friend for explaining the code in detail but when i run it using values it does not give anything

Why don't you post the code you tried so that we can see it too?

#include<stdio.h>


main()



float xmin,x;
x=5.6;


if (abs(x) < xmin)

if(x > 0)

x = xmin;

else

x = -xmin;

i did not include the braces as it does not accept here with braces assume i put the braces

Ok first wrap your code in code tags next time It is easy. You write
[key] /* Your code here */ [/key] Replace key with code in order this to work

In your code you do not give a value to xmin, so your flow of code will not go into the if structure you have.

Also if you want to see something put some printf's

Finally you usually write

Code:

int main(void)
{
       ....
       return 0;
}
