一部分用户对把三段式 for loop (for i := 1; i < n; i++)中的循环变量也修改成 per iteration 这个提议提出了质疑,主要理由是会和其他语言(主要是C以及一众类C语言)的行为不一致,其他语言背景的用户迁移过来也会被坑到。(C# 迁移到 per-iteration 循环变量作用域的时候就只迁移了 foreach,而没更改三段...
and the increment. The initialization part is executed only once. The body of the for statement is executed when the condition is true. If the condition returns false, the for loop is terminated. After the statements in the block are executed, the for loop switches to the third part, where...
