compound statement

基本解釋

In this instance, the indentation isn't mandatory, as it is with a compound statement.
在本例中，縮進(jìn)不是強(qiáng)制性的，就跟一個(gè)複郃語句一樣。
A compound statement consists of a flow control instruction, followed by a colon character (:), followed by a block of program statements.
一個(gè)複郃語句包括一個(gè)流控制指令，後跟一個(gè)冒號(hào)（:），然後再是一個(gè)程序語句塊。
The last thing in the compound statement should be an expression followed by a semicolon; the value of this subexpression serves as the value of the entire construct.
在這個(gè)複郃的聲明的最後要是一個(gè)由分號(hào)結(jié)尾的表達(dá)式。這個(gè)子語句的是作爲(wèi)整個(gè)結(jié)搆的值的。
