It is possible to solve this problem using loop or a recursion method. And we have already seen the solution using #define directive (Macro expansion) but what if all three are not allowed? A simple solution is to write the number 100 times in cout statement. A better solution is to use concept of Concept of setjump and longjump in C.
CPP
Output :
100 times 1.
Time complexity : O(n)
Auxiliary Space : O(1)
The same can be written for C also.
