Solidity Programming Language – Loops (For, While, Do-While)

In Solidity, loops are used to repeat a set of instructions multiple times. There are two main types of loops in Solidity: for loops and while loops.

For Loops:. It consists of an initialization statement, a condition, and an iteration statement.

While Loops: The while loop continues executing as long as the specified condition is true.

It’s important to be cautious when using loops in smart contracts to avoid gas-related issues. Infinite loops or loops with an undetermined number of iterations should be avoided to prevent potential attacks on the contract due to excessive gas consumption.

Do-While Loops: Solidity does not have a built-in do-while loop like some other programming languages. However, you can simulate the behavior of a do-while loop using a while loop with a pre-check.

Keep in mind that while this approach achieves the behavior of a do-while loop, you should be careful with the loop conditions to prevent infinite loops and excessive gas consumption in your smart contracts.
