Question
**Convert the following into Pep/9 assembly language:**

```cpp
#include <iostream>
using namespace std;

char ch;

int main() {
    cin.get(ch);
    ch--;
    cout << ch << endl;
    return 0;
}
```

**Explanation:**

This C++ program performs the following tasks:

1. Includes the iostream library for input and output operations.
2. Uses the standard namespace.
3. Declares a character variable `ch`.
4. In the `main` function:
   - Reads a character from standard input using `cin.get(ch);`.
   - Decrements the character value stored in `ch` using `ch--;`.
   - Outputs the decremented character value to standard output followed by a newline using `cout << ch << endl;`.
5. Returns an integer value `0` at the end of the program to indicate successful execution.

To convert this into Pep/9 assembly language, the operations for reading input, decrementing a character, and outputting to the console will need to be expressed in Pep/9 assembly instructions.
