程序员t5和t7差距

**Procedure:** In computer programming a specific set of instructions together called a procedure. Depending on the programming language it can be called as subroutine, subprogram or a function.

**过程：**在计算机编程中，一组特定的指令统称为过程。 根据编程语言的不同，它可以称为子例程，子程序或函数。

**Function:** It is one of the basic concept in programming of computer. As it name says, it performs a function (work). It can be either user defined or system defined. More technically it is a block of code in program which performs specific task.

**功能：**它是计算机编程中的基本概念之一。 顾名思义，它执行一项功能(工作)。 它可以是用户定义的，也可以是系统定义的。 从技术上讲，它是程序中执行特定任务的代码块。
