Question

2. Next Destination
by CodeChum Admin

Yay! Because of your help, we're now at our first destination.

However, I do not know what's our next destination huhu I guess being a tour guide is not my forte. Oh wait, I see that there's a signage here pointing to another signage there. Perhaps if we follow the connections, we will know what the next destination is.

Instructions:

In the code editor, there are three things present:
An integer value representing the next destination
Pointer #1 which represents the first signage
And Pointer #2 which represents the second signage
For this problem, you need to do two things:
Assign the address of the integer value (or the next_destination) to Pointer #2
Assign the value of Pointer #2 to Pointer #1
Using Pointer #1 and the dereferencing operator, print the value of the next_destination

Output

Next destination = 20

next_destination) to
main.c
< >
+ c
Pointer #2
2. Assign the value of Pointer
1 #include<stdio.h>
#2 to Pointer #1

3 - int main(void) {
3. Using Pointer #1 and the
dereferencing operator,

int next_destination

print the value of the
int *pointer_1, *pointer_2;
next_destination
