Question

g If you write a C function, named swap, that takes two integers as input arguments and swap them internally. Assume the function returns nothing. Write down the function declaration

Answer 1

Answer:

void swap(int number1, int number2) {

   printf("Values before swapping: %d %d \n", number1, number2);

   

   int temp;

   temp = number1;

   number1 = number2;

   number2 = temp;

   

   printf("Values after swapping: %d %d \n", number1, number2);

}

Explanation:

- Print the initial values to see the change

- Declare a temporary variable temp

- Assign the value of the number1 to the temp

- Assign the value of the number2 to number1 (The first number is swapped)

- Assign the temp value to the number2 (The second number is swapped)

- Print the new values
