Draw a flowchart and write pseudocode to represent the logic of a program that allows the user to enter two values. The program outputs the sum of and the difference between the two values.

read x,y

print x+y, x-y

this allows for negative difference, if x<y
you might have to make some adjustments if you always want to get a positive difference.

To represent the logic of a program that allows the user to input two values and outputs their sum and difference, we can use the following flowchart:

```
Start
├─> Input value1
├─> Input value2
├─> Calculate sum = value1 + value2
├─> Calculate difference = value1 - value2
├─> Output sum
├─> Output difference
End
```

And here is the pseudocode that corresponds to the flowchart:

```
Start
Display "Enter value1:"
Input value1

Display "Enter value2:"
Input value2

sum = value1 + value2

difference = value1 - value2

Display "The sum is: " + sum

Display "The difference is: " + difference

End
```

Please note that the syntax and exact commands may differ based on the programming language you are using.

Sure! Here's a flowchart and pseudocode representing the logic of the program:

Flowchart:
```
Start
Input first value (A)
Input second value (B)
Sum = A + B
Difference = A - B
Output Sum
Output Difference
End
```

Pseudocode:
```
1. Start
2. Print "Enter first value (A): "
3. Input A
4. Print "Enter second value (B): "
5. Input B
6. Sum = A + B
7. Difference = A - B
8. Print "Sum: " + Sum
9. Print "Difference: " + Difference
10. End
```

To implement this logic in a programming language, you can translate the pseudocode according to the syntax and conventions of the particular language you are using. For example, in Python it would look like this:

```python
# Prompt for first value
A = float(input("Enter first value (A): "))

# Prompt for second value
B = float(input("Enter second value (B): "))

# Calculate sum and difference
Sum = A + B
Difference = A - B

# Output the results
print("Sum:", Sum)
print("Difference:", Difference)
```

Note that the pseudocode assumes the values entered by the user are floating-point numbers. If you require integer inputs, you can modify the code accordingly.
