im trying to make a replace function, but idk how to get a string as a function parameter
#how would i get a string as a function parameter
dim turtle
fn replace(string: *const []u8, to_be_replaced: u8, replace_with: u8) *const []u8 {
var result: *const []u8 = string;
for (result, 0..result.len) |char, i| {
if (char == to_be_replaced) {
result[i] = replace_with;
}
}
return result;
}```error: src/main.zig:37:45: error: expected type '*const []u8', found '*const [17:0]u8'

I think you wan []const u8

a *const []u8 is a double pointer - are you sure this is what you want?
dim turtle
[]const u8 makes it that result[i] = replace_with; results in an error

*const [17:0]u8 is a pointer to a array of u8. []const u8 (or []u8) are more or less structs, that have a pointer and a len field
royal dirge
there's std.mem.replace, std.mem.replaceOwned, and std.mem.replaceScalar - perhaps you can already use one of them?
even if you want to try to implement the function yourself, it might be beneficial to look at their signatures, to see how they handle things

`[]const u8` makes it that `result[i] = replace_with;` results in an error
ok, then use []u8. But know, that you won't be able to pass things with type *const [17:0]u8, because *const [17:0]u8 are immutable and []u8 are not. But use std functions, if possible.
dim turtle
ok
