原文:

The terms foobarfoobarbaz and qux are sometimes used as placeholder names (also referred to as metasyntactic variables) in computer programming or computer-related documentation.[1]They have been used to name entities such as variablesfunctions, and commands whose purpose is unimportant and serve only to demonstrate a concept. The words themselves have no meaning in this usage. Foobar is sometimes used alone; foobar, and baz are sometimes used in that order, when multiple entities are needed.

翻译:

术语foobarfoobarbaz 和qux经常在计算机编程或计算机相关的文档中被用作占位符的名字。当变量,函数,或命令本身不太重要的时候,foobarfoobarbaz 和qux就被用来充当这些实体的名字,这样做的目的仅仅是阐述一个概念,说明一个想法。这些术语本身相对于使用的场景来说没有任何意义。Foobar经常被单独使用;而当需要多个实体举例的时候,foo,bar,和baz则经常被按顺序使用。 

#include <stdio.h>

int foobar(int *pi)
{
    *pi = 1024;
    return *pi;
}

int main()
{
   char foo[] = "Hello,";
   char bar[] = "World!";
   printf("%s %s\n", foo, bar);
 
   int baz = foobar();
   printf("%d, baz");
   return 0;
}
