I have a simple sentence in a string. I want to print each word on a new line or otherwise just do some calculation on each word?
Is there something similar to python's "Hello World".split() in zig? Something like this:
var arr = std.strings.split("Hello world");
Here is the simplest way I found
const std = @import("std");
pub fn main() !void {
var it = std.mem.split(u8, "Hello World", " ");
while (it.next()) |x| {
std.debug.print("{s}\n", .{x});
}
}
It looks like splitting is implemented in the standard mem module. .split returns SplitIterator which is a structure with a .next() method. When .next() returns null, the while stops. This is a common pattern in zig:
