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 program to print one 100 times.
#include <iostream>
#include <setjmp.h>
using namespace std;
jmp_buf buf;
int main()
{
int x = 1;
// Setup jump position using buf
setjmp(buf);
cout << "1"; // Prints 1
x++;
if (x <= 100)
// Jump to the point setup by setjmp
longjmp(buf, 1);
return 0;
}
Output :
100 times 1.
Time complexity : O(n)
Auxiliary Space : O(1)
The same can be written for C also.
