C语法归约之语句（5）

这是语法归约最后一部分了，后面文法当中还有个外部归约。它已经在前面以及这里都提及到了，也就是把全局声明定义和函数定义整合的过程，最后归约成一颗完整的树。根结点就是translation-unit，因此不再单独示例！

### 示例代码 ###

void foo()
    {
    start:
    	for(i = 1; i < NR; ++i) { 
    		if(i % 13 == 0)
    			goto start;
    	}
    }
    
    void foo()
    {
    	a = b + c;
    	return;
    }
    
    void foo()
    {
    	if(a < 0)
    		a = -a;
    	else
    		a = 1;
    
    	if(a > 0)
    		a = 1;
    	else if(a < 0)
    		a = -1;
    	else
    		a = 0;
    
    	switch(a) {
    		case 1:
    			break;
    		case 2:
    			{
    				a *= a;
    				break;
    			}
    		default:
    			{
    				a = a + 2;
    				break;
    			}
    	}
    }
    
    void foo()
    {
    	for(i = 0; i < NR; ++i) { 
    		i += 2;
    	}
    
    	for(;;) {
    		++i;
    		if(i == 10)
    			break;
    	}
    
    	while(1) {
    		if(i == 10)
    			break;
    		if(i == 5)
    			continue;
    		++i;
    	}
    
    	do {
    		++i;
    	}while(i < 10);
    
    }
    
    int foo()
    {
    	return 1;
    }

### 总结 ###

C语言语法归约到此结束！多余总结不说了，提醒一点吧！文法不是C的全部，它太宽泛了，如果只看它的话，能得到非常复杂的组合出来，真正的C还要包括语义分析部分，也就是说把文法推导出来东西进行有意义化！即文法上推出的东西不是全部都合法的！因此，c只用了文法推导结果中的一个子集，而不是全集！好比汉语词汇组合说出来的东西不是全部都有意义，可以有脏话废话和不是人话^\_^，这得需要人大脑，方言规则，社会伦理道德等等来解析！就这么多吧！谢谢你的阅读！
