I do not understand where the second number in the sums in the image come from. For example, in the first one where does the6 in (4 + 6 = 10) come from?

[@pedrofranco7247]

4+3+2+1 = 10

[@testingsomething5280]

@@pedrofranco7247 I get it but where did the 6 come from?

[@pedrofranco7247]

@@testingsomething5280 It comes from the iteration below: 3+3 =6, in which the second 3 comes from the other iteration: 2+1=3, and the 1 comes from yet another iteration: 1+0=1. Everything together is the same as 4+3+2+1=10

[@sameershwaikeh]

its n+sum(n-1 ): if n =4 , then n-1 = 3 , the sum of 3 is : 1 +2+3 = 6 , so n+sum(n-1)= 4 +6 =10

Answer is C. a Recursive function doesn't have to return value all the time. It can be used to just pass parameters.

#include #include int main() { // Write C code here int number,result; printf("Write a whole number:"); scanf("%d", &number); result = factoriel(number); printf("Factoriel = %d", result); return 0; } int factoriel(int n){ if (n != 0){ return n * factoriel(n-1); } else { return n+1; } }

[@datuboharry6103]

You’ll use (n != 1) here since you’re dealing with multiplication. Hence the function always returns 0

[@datuboharry6103]

If you leave it at 0, it’ll run “return 1 * (1-1)” which is 1 * 0 on the last loop. Making it return zero always

[@onomemafuru9496]

How does the compiler know to convert sum(number) to sum(n) since number and n are not same thing, wouldn't it be better to be consistent with sum(number) ?

[@Solenya.]

'n' is used as the variable within the sum() function itself. You can think of the sum(n) part as a blueprint. When the function is called, the compiler follows the blueprint by substituting 'number' everywhere there is an 'n'.
