int a=0; cout<<a[2]; //a是整型,却当数组来用了 二十、conflicting declaration 'xxx' 对某个东西的冲突说明,比如你定义的变量类型,与你之前说明的不一样 1.既是变量,又是数组(或指针,或引用) int a=0; int a[5]={0}; //既说a是整型,又说它是数组,冲突说明了 2.有对它的不同类型的定义(声明) int a=0;
下面的例子展示了一些不好的做法if (a) do_b();else do_c();if (a) do_a(); else do_b();空while循环、do-while循环或for循环必须包含花括号/* OK */while (is_register_bit_set()) {}/* Wrong */while (is_register_bit_set());while (is_register_bit_set()) { }while (is_register...
