Question
What does this code print?int print(int nb){ if (nb < 0) { return (0); } printf("%d", nb + print(nb - 1)); nb --; return (nb);}int main(void){ print(4); return (0);}
Solution
The code you provided is written in C language. However, it seems to have some logical errors. The function print is supposed to be a recursive function that prints the numbers from the input number down to 0. However, the printf statement is trying to print the sum of the current number and the result of the recursive call, which is not correct. Also, the decrement of nb after the printf statement has no effect because the value of nb is not used after that.
Here is a corrected version of the code:
#include <stdio.h>
void print(int nb){
if (nb < 0) {
return;
}
printf("%d ", nb);
print(nb - 1);
}
int main(void){
print(4);
return 0;
}
This code will print: 4 3 2 1 0
