If statement with ? and : [duplicate]

Answer 1

The ternary operator ?: is a minimize if statement which can reduce this:

if(foo)
    exprIfTrue();
else
    exprIfFalse();

To this:

(foo) ? exprIfTrue() : exprIfFalse() ;

Personally, I avoid using it because it easily becomes unreadable. The only good example of use is to display the status of a flag in a printf:

int my_flag = 1;

printf("My flag: %s\n", my_flag ? "TRUE" : "FALSE" );
