printing not working properly [0.13.0]

[next patrol]

The code:

const std = @import("std");
const print = std.debug.print;

const TITLE = "Simple-Calculator";

fn getNumberInput(statement: []const u8) ![]u8 {
    var input: [1024]u8 = undefined;

    print("{s} ", .{statement});

    const result = try std.io.getStdIn().reader().readUntilDelimiter(&input, '\n');
    return result;
}

pub fn main() !void {
    print("================================\n-|Welcome To {s}|-\n================================\n", .{TITLE});
    
    const firstNumber = try getNumberInput("Enter your first number:");

    print("You entered: {s}!\n", .{firstNumber});
}

The output:

================================
-|Welcome To Simple-Calculator|-
================================
Enter your first number: 88
You entered: ��!

[honest sun]

you're returning a slice to stack memory

i think either do everything you need to and return a number or accept a destination slice into getNumberInput

Further reading so you will remember next time 🙂 (at least for the stack case which is easier to not do)
