how to print 1 to 100 without loop,iteration,goto.

Answer 1

So you use a concept of recursion if you do not want to use a loop. Pretty much the function calls itself again until it gets to the point to break it.

Here is example code

#include <iostream>
using namespace std;

void count(int start) {
if(start <= 100) {
cout << start << endl;
start++;
count(start);
}
}

int main() {

int start = 1;
count(start);
}

Answer 2

trick: use foreach "function"
#include <iostream>
#include <numeric>
#include <algorithm>
using namespace std;

int main() {
int oneToHundred[100];
iota(oneToHundred, oneToHundred + 100, 1);
for_each(oneToHundred, oneToHundred + 100, [](int i){cout << i << endl;});
return 0;
}
