Just like other programing languages solidity also support the for loop function and the syntax is quite similar to for loop function in JavaScript.

In this article i will explain what for loop is and how to create this function in solidity.

Introduction

In solidity if we have a large number of data (like millions of it ) and will like to run through those data to make decisions on it, we can automate the process of checking through these data by creating a function called for loop function.

A for loop function is a function use for integrating or looping through large number of data automatically.

What a for loop function does is that , it loops through the data one after the other and then execute decisions related with the data.

HOW TO DECLARE FOR LOOP FUNCTION IN SOLIDITY

for loop function are being created inside a function and it is a three part statement

(1) create a function

(2) Inside the curly bracket were codes to be executed by the function are written declare the for loop keyword “for” and then open a parenthesis

(3) declare an integer variable (I) which represent the index of the data and initialize it (this is the first part of the statement)

(4) Declare the length of the data using .length method (second part of the statement)

(5) Specify the operation of the index (third part of the statement)

(6) create a new curly bracket that will hold the decisions to be executed

Conclusion

Thus that is a simple explanation on how to create a for loop function in solidity , i hope you enjoy reading through the article. If you have any question feel free to put that in the comment section below
