A Puzzle on C/C++ R-Value Expressions
Last Updated :

What will be the output of following program?
#include <stdio.h>
int main()
{
int i = 0xAA;
~i, printf ( "%X\n" , i);
return 0;
}
|
Output:Â 0xAA
No change in i value, the emphasis is on l-value and r-value expressions. The expression ~i is an r-value, it has to be assigned to an l-value to retain the change.
