Question 1: Calculate the sum of all numbers (including this number) up to a natural number given in the
main function using a recursive function. Solution (5 Minutes)
Output
Enter a positive integer:
3
Initially, the sum() is called from the imain() function with number passed as an argument.
Suppose, the value of num is 3 initially. During next function call, 2 is passed to the sum()
function. This process continues until num is equal to 0.
When num is equal to 0, the if condition fails and the else part is executed returning the
sum of integers to the main() function.
