void countUp (int num)

{

if (num==0) / /base case.

return;

countUp (num-1); //Recursive call.

cout<
}

for input num=25

Output:-1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

Explanation:

I have used recursion to print the numbers the function is in c+ + language. In every recursive call we are decreasing num by 1. As the base case is reached. Then it will backtrack from 1 to num and then we are printing while backtracking.
