For loops

For loops are used to iterate over arrays (and other types, to be discussed later). For loops follow this syntax. Like while, for loops can use break and continue. Here, we've had to assign values to _, as Zig does not allow us to have unused values.

const expect = @import("std").testing.expect;

test "for" {
//character literals are equivalent to integer literals
const string = [_]u8{ 'a', 'b', 'c' };

for (string, 0..) |character, index| {
_ = character;
_ = index;
}

for (string) |character| {
_ = character;
}

for (string, 0..) |_, index| {
_ = index;
}

for (string) |_| {}
}
