Printing 1 to 1000 without loop or conditionals?

Question

**Task**: Print numbers from 1 to 1000 without using any loop or conditional statements. Don't just write the `printf()` or `cout` statement 1000 times.How would you do that using C or C++?

Answer 1

You can use recursion to implement this:

inline int my_print(int i) {

(i -1) && my_print(i-1); std::cout<<i << " "; return 1;

}

Anding of (i-1) makes sure the recursion stops when i is 1.

Now my_print(1000) will print 1 through 1000
