For Loop To Generate 1-100

[uthmanabayomi]

i'm writing an a for loop function to generate numbers from 1- 100 and i'm getting errors. This is my code : function returnNumers () public pure returns (uint[] memory){

    for (uint i = 0;  i < 100 ; i++){

         numbers[i] = i + 1;
    }
    return numbers;
}

I know the variable "numbers" is not declared here but i have tried declaring it but it's not working, kindly provide a solution if you can. And make sure you run the code before pasting here too to ensure its working. Thank You

Hello @uthmanabayomi, What error are you getting?

@uthmanabayomi would be helpful if you share the entire code as it's a bit difficult to understand what you're trying to do. I can see you're using the pure modifier (you can't access or modify any state variables) so I guess you want to do everything in memory. Because you can't initialize dynamic arrays in memory you will have to define how much memory your variable will take.

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.24;

contract Test {
    function returnNumbers() public pure returns (uint[100] memory) {
        uint[100] memory numbers; // initialize the array with fixed size

        for (uint i = 0; i < 100; i++) {
            numbers[i] = i + 1; 
        }
        return numbers; 
    }
}

Sorry i'm just writing back, i was able to fix it after initializing the array, yours was helpful Thank You
