Step 1. Call by Values - Swap Function 1. Declare a function named swap on the top of your main to accept two int variables and returns void. 2. Write your main function as follow: int main() ( int x = 2; int y = 14; printf("Before swap method: x=%d, y=%d.\n", x,y); swap(x,y); printf("After swap method: x=%d, y=%d.\n", x,y); return 0; } 3. Develop swap function to swap two variables. void swap (int a, int b) ( //write a code to swap a and b. printf("In swap function a=%d, b=%d.\n", a,b); return; Output sample: Before swap method: x=14, y=2. In swap function a=14, b=2. After swap method: x=2, y=14. Step 2. Call by Reference. As you saw in step 1, to effectively exchange the values of two variables we can't use a function as call by values. 1. Change the function declaration at the top of the main functon to accept two pointers to int. 2. Change the swap function header to accept two pointers to int as a parameter list. 3. Change the swap function's body to work on two pointers to exchange the values of two variables.

Hello. Please answer the attached C programming question correctly by fulfilling all of the steps on the 2 pics. Please do not use very advanced syntax to solve the problem. 

*If correctly fulfill and do all of the steps correctly, I will give you a thumbs up. Thanks.

### Step 1. Call by Values - Swap Function 1. **Declare a function** named `swap` on the top of your main to accept two `int` variables and return `void`. 2. **Write your main function** as follows: ```c int main() { int x = 2; int y = 14; printf("Before swap method: x=%d, y=%d.\n", x, y); swap(x, y); printf("After swap method: x=%d, y=%d.\n", x, y); return 0; } ``` 3. **Develop swap function** to swap two variables. ```c void swap(int a, int b) { // write a code to swap a and b. printf("In swap function a=%d, b=%d.\n", a, b); return; } ``` ### Output Sample: ``` Before swap method: x=14, y=2. In swap function a=14, b=2. After swap method: x=2, y=14. ``` ### Step 2. Call by Reference As you saw in step 1, to effectively exchange the values of two variables we can’t use a function as call by values. 1. **Change the function declaration** at the top of the main function to accept two pointers to `int`. 2. **Change the swap function header** to accept two pointers to `int` as a parameter list. 3. **Change the swap function’s body** to work on two pointers to exchange the values of two variables.

## Swapping Function in C Programming This example illustrates how to implement a swapping function in C to interchange the values of two variables using a function. ### Code Explanation: The code provided aims to define a `swap` function that exchanges the values of two variables and then uses this function within the `main` function. 1. **Function Declaration:** ```c void swap(-----, -----); ``` 2. **Main Function:** ```c int main() { int x = 2; int y = 14; printf("Before swap method: x=%d, y=%d.\n", x, y); // Call swap function printf("After swap method: x=%d, y=%d.\n", x, y); return 0; } ``` 3. **Swap Function Definition:** ```c void swap(-----, -----) { // Write the code to exchange the values of the parameter values printf("In swap function a=%d, b=%d.\n", -----); return; } ``` ### Output Sample: ```plain Before swap method: x=2, y=14. In swap function a=14, b=2. After swap method: x=14, y=2. ``` ### Steps to Implement: 1. **Function Declaration:** - The `swap` function should accept two pointers to integers to enable the swap of variables within the function. ```c void swap(int *a, int *b); ``` 2. **Main Function Implementation:** - Define two integer variables `x` and `y`. - Print their values before the swap. - Call the `swap` function with the addresses of `x` and `y` to swap their values. - Print the values after the swap. ```c int main() { int x = 2; int y = 14; printf("Before swap method: x=%d, y=%d.\n", x, y); // Call swap function swap(&x, &y); printf("After swap method: x=%d, y=%d.\n", x, y); return 0; } ``` 3. **Swap Function Implementation:** - Implement the logic
