This section explains how to write for statements (repeat) in Solidity.
Syntax
Here is how to write a for statement in Solidity.
for (initialization; conditional expression; iterative expression) {
Processing
}
Sample Code
// SPDX-License-Identifier: GPL-3.0
pragma solidity >=0.7.0 <0.9.0;
contract Test {
uint[] numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
function getSum() public view returns(uint) {
uint sum = 0;
// Loop over the numbers array by the number of elements (iterative processing)
for (uint i = 0; i < numbers.length; i++) {
sum += numbers[i];
}
return sum;
}
}
The for statement is also used in the same way as in other programming languages. It is important to remember it in combination with arrays.
