Software Development: Difficult to Solve the Problem
Introduction
Software development is basically solved by coding. As mentioned below, you should focus on a simple and clear method so that this process can be as effective as possible.
The purpose is to understand the problem, solve the design, and then check. This article describes these steps in the simplest way.
1. Understand the Question
Before writing any code, please take some time to understand the problem.
Read the question carefully: Take time to understand all details.
If the explanation is unclear.
Determine input and output: Determine the reasons for the input requirements and expected output.
For example
If you ask for two numbers, the input is two numbers, and the output is their total.
2. Divide the Problem into Small Steps
If the problem seems big, break it down into smaller, simpler steps.
Solve the problem slowly, then combine all the steps together.
Example:
Add two numbers.
These steps are:
1. Get the first number.
2. Get the second number.
3. Add the two numbers together.
3. Plan Your Solution
Don't write the code in a hurry. First, plan your program.
Write the steps to solve the problem with simple words.
Consider special circumstances, such as empty or accidental input.
Example:
This is a plan to add two numbers:
1. Get the first number.
2. Get the second number.
3. Add the two numbers together.
4. Show the result.
Write Your Code
Now, write the code according to the planned steps. Ensure that your code is simple and easy to follow.
Use clear and meaningful variable names to prevent confusion.
Example Code:
# Add two numbers
def add_numbers(a, b):
return a + b
# Test
result = add_numbers(5, 3)
print(result) # Output: 8
Test Your Code
After writing the code, test it. Enter test cases regularly. Check for special circumstances, such as zero input or large inputs.
Sample Test Cases:
1. Input: 5, 3 → Output: 8
2. Input: 0, 0 → Output: 0
3. Input: -1, 4 → Output: 3
Repair Errors
If your code does not work, don't panic!
Identify the problem and slowly solve the error.
Practice
The more mistakes you rectify, the more proficient you become.
Complete basic tasks before moving onto more complex ones.
Although there might be challenges dealing with the process of the software’s development, remember to tackle the problem by first framing it, then creating a plan for a solution that involves coding, testing, and debugging.
With practice, you will become a skilled problem solver and the best programmer!
