4. Swapping Places
by CodeChum Admin

Phew! Thanks to your help, I was able to entertain the two bored guys.

But I would like to ask for your help one last time. I see that there are is this older guy who's bullying a kid. I can reprimand the older guy but I want to handle this situation peacefully.

I'm planning to swap the kid's place to another older guy's place so the bully won't be close to the kid. Please help me swap them both.

Instructions:

You are given a main() function that asks the user for two integer inputs and passes these two values to a function call of the swap() function.
The swap function doesn't exist yet so your task is to make its function declaration and implement its function definition.
Its details are the following:
It accepts two integer addresses as its parameters
It will swap the values found in the two integer addresses. For example, if we have two integer values, a = 5 and b = 10, and we pass their addresses to the function call, by the end of the function, the two integer values will be swapped. Meaning, a would now be equal to 10 and b would now be equal to 5.
Do not edit anything in the main() function.
Input

1. First integer value

2. Second integer value

Output

Enter value 1: 5
Enter value 2: 10

New value 1: 10
New value 2: 5

Input
main.c
>
+ c
1. First integer value
1 #include<stdio.h>
2
2. Second integer value
// TODO: Implement the function declaration of swap() here

int a, b;
Output

printf("Enter value 1: ");
scanf("%d", &a);
printf("Enter value 2: ");
scanf("%d", &b);
Enter value 1: 5

New value 2: 5

swap(&a, &b);

printf("\nNew value 1: %d\n", a);
printf("New value 2: %d\n", b);
