Program to Find the Sum of Even Single-Digit Numbers

Here is a program in Python that finds the sum of even single-digit numbers:

sum = 0
for num in range(0, 10, 2):
    sum += num
print("The sum of even single-digit numbers is:", sum)

Explanation: - We initialize a variable `sum` to 0 to store the sum of even single-digit numbers. - We use a `for` loop to iterate over the range from 0 to 10 with a step of 2. This ensures that we only consider even numbers. - Inside the loop, we add each even number to the `sum` variable. - Finally, we print the sum of even single-digit numbers.

The output of this program will be: ``` The sum of even single-digit numbers is: 20 ```
