 for info on how our automated program grader works.
### Sample Code:
```cpp
#include <iostream>
using namespace std;
int main() {
char a;
char b;
char c;
cin >> a;
cin >> b;
cin >> c;
// Output all permutations of a, b, and c
cout << a << b << c << " ";
cout << a << c << b << " ";
cout << b << a << c << " ";
cout << b << c << a << " ";
cout << c << a << b << " ";
cout << c << b << a << " ";
cout << endl;
return 0;
}
```
### Explanation:
1. **Include Header**
```cpp
#include <iostream>
```
Including the necessary library for input-output stream operations.
2. **Namespace Declaration**
```cpp
using namespace std;
```
Declaring the standard namespace for convenience.
3. **Main Function**
```cpp
int main() {
char a;
char b;
char c;
cin >> a;
cin >> b;
cin >> c;
// Output all permutations of a, b, and c
cout << a << b << c << " ";
cout << a << c << b << " ";
cout << b << a << c << " ";
cout << b << c << a << " ";
cout << c << a << b << " ";
cout << c << b << a <<](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd30ea730-ba6b-4d49-90df-80ffc6e77ea4%2F0a20f156-9c58-4762-ae56-e4a2aba716d6%2Fyn2topp_processed.png&w=3840&q=75)
Transcribed Image Text:### Output All Combinations of Character Variables
In this exercise, you are required to output all combinations of the character variables `a`, `b`, and `c` in the order shown below. After the final output, end with a newline. If `a = 'x'`, `b = 'y'`, and `c = 'z'`, then the output is:
```
xyz xzy yxz yzx zxy zyx
```
#### Note:
Our autograder automatically runs your program several times, trying different input values each time to ensure your program works for any values. This program is tested three times, first with the inputs `x y z`, then with the inputs `# $ %`, and finally with the inputs `1 2 3`.
