// // Now that we've learned about arrays, we can talk about strings. // // We've already seen Zig string literals: "Hello world.\n" // // Zig stores strings as arrays of bytes. // // const foo = "Hello"; // // Is the same as: // // const foo = [_]u8{ 'H', 'e', 'l', 'l', 'o' }; // const std = @import("std"); pub fn main() void { const ziggy = "stardust"; // (Problem 1) // Use array square bracket syntax to get the letter 'd' from // the string "stardust" above. const d: u8 = ziggy[???]; // (Problem 2) // Use the array repeat '**' operator to make "ha ha ha". const laugh = "ha " ???; // (Problem 3) // Use the array concatenation '++' operator to make "Major Tom". // (You'll need to add a space as well!) const major = "Major"; const tom = "Tom"; const major_tom = major ??? tom; // That's all the problems. Let's see our results: std.debug.print("d={u} {}{}\n",.{d, laugh, major_tom}); // // Keen eyes will notice that we've put a 'u' inside the '{}' // placeholder in the format string above. This tells the // print() function to format the values as a UTF-8 character. // If we didn't do this, we'd see '100', which is the decimal // number corresponding with the 'd' character in UTF-8. // // While we're on this subject, 'c' (ASCII encoded character) // would work in place for 'u' because the first 128 characters // of UTF-8 are the same as ASCII! // }
