Write a program of inline function, C/C++ Programming

Assignment Help:

Here is a program that uses an inline function to compute and return the absolute value of its input argument.

# include

inline int abs(int x)

{

                 return x <0? -x : x ;

}

void main( )

                {

                  for (int i=-2 ; i<2 ; ++i)

                   {

           int value = abs(i) ;

           printf ("Absolute value of %+d = %+d\n",i, value);

         } 

      }

The output is:

Absolute value of -2 =+2

Absolute value of -1 =+1

Absolute value of +0 =+0

Absolute value of +1 =+1

When the call to the abs ( )  function is encountered, the compiler, instead of making a function call, generates this assembly code.
