Debugging with console refers to the process of using console output statements to debug and troubleshoot code. It involves adding print statements or log statements in your code to display specific values or messages at different points during program execution.
Here is an example of how you can use console debugging in a programming language like Python:
```python
def calculate_sum(a, b):
print("Calculating sum...")
print("a =", a)
print("b =", b)
result = a + b
print("Sum =", result)
return result
# Main program
num1 = 5
num2 = 10
print("Start of program")
# Call the function and display the sum
sum_result = calculate_sum(num1, num2)
print("End of program")
```
In the above code, we have a function `calculate_sum` that calculates the sum of two numbers `a` and `b`. We have added print statements at various points to print out the values of `a`, `b`, and the result of the sum. By examining these console outputs, we can track the flow of the program and verify if the calculations are correct.
When running this code, you will see the console output displaying messages and values at different stages of the program execution. This can help you identify any issues, validate input values, and understand how your code is functioning.
Console debugging is a simple and effective way to gain insights into your code and identify potential problems. However, for more complex scenarios or larger codebases, using a dedicated debugger tool with breakpoints and step-by-step execution may provide more advanced debugging capabilities.
