Question

What is the output of the program code given below, when the value of x = 294?

int simple(int x)
{return (x<=0)? 0: x + simple(x/10);}

Answer 1

325

Explanation:

The statement:

return ((x<=0)?0:x+simple(x/10)); performs itself recursively using x/10.

Hence the processing of x + simple(x/10) is calculated as 294 + 29 = 325.
