Features of Cat++

Language Feature	Code Example
Integer Scalar Variables	meow x :3 meow y :3 meow z :3 meow avg :3
One-dimensional Arrays of Integers	meow a[12] :3 a[0] = 3 :3
Assignment Statements	meow x = 1 :3 x = 2 :3
Arithmetic Operators	meow x = 1 + 1 :3 x = x + 1 :3 meow y = x - 1 :3 y = x * y :3 meow z = y / 2 :3 z = 1 + x - y * z / 4 :3
Relational Operators	x != y :3 x < y :3 x > y :3 x <= y :3 x >= y :3 x == y :3
While Loop	Traditional: hunt(x < 10) {   x = x + 1 :3 } With break statement: hunt(x > 10) {   purrhaps(x == 10000) {     neuter :3   } } With continue statement: hunt(x > 10) {   purrhaps(x == 10000) {     keep_going :3  } }
If-then-else Statements	purrhaps(y < 3) {   y = y + 1 :3 } else purrhaps(y > 3) {   y = y - 1 :3 } else {   x = x + 1 :3 }
Read and Write Statements	Print to terminal: scratch(x) :3 scratch(x + 2) :3 Read from terminal: litter(x) :3
Comments	O_O this is a comment meow x = 2 :3 O_O this will be ignored
Functions	purr meow add(meow x, meow y) {   meow z = x + z :3   knead z :3 } purr meow main() {   meow a = add(x, y) :3 }
