for' loop initial declaration used outside C99 mode 1. 2 原因 c99是允许在for循环中声明变量的,但是如果使用的标准为c99之下的话,则不允许这么做,这里我是在for循环里面定义了变量如下 for (int i = 0; i < 10; ++i) { /** * */ } 1. 2. 3. 4. 5. 6. 3 解决办法 我们在编译C程序的...

int32_t a = sum (4, 3); /* Wrong */ 不要在变量/函数/宏/类型中使用_或前缀。这是为C语言本身保留的 对于严格的模块私有函数,使用prv_name前缀 对于包含下划线_char的变量/函数/宏/类型,只能使用小写字母 左花括号总是与关键字(for,while,do,switch,if,…)在同一行 ...
C99 标准(指c语言的,大概就是这个) 不允许在for的内部声明变量,所有变量事先声明就好了 C
