控制流

1. 条件语句（if-else）

require("basic");
var(a) = int:5;
if(a > 3) {
    basic.print("a 大于 3");
} else {
    basic.print("a 不大于 3");
}

2. 循环

(1) for 循环

require("basic");
for(var(i) = int:0; i < 5; i = i + 1) {
    basic.print(string:"循环次数: " + string:i);
}

(2) while 循环

require("basic");
var(j) = int:0;
while(j < 3) {
    basic.print(string:"while 循环: " + string:j);
    j = j + 1;
}
