“declaration may not appear after executable statement in block”错误解析 1. 错误含义 “declaration may not appear after executable statement in block”这个编译错误信息意味着在C或C++程序中,你在一个代码块(如函数、循环或条件语句内)中先执行了可执行语句(如赋值、函数调用等),然后尝试在该代码块的同一...
编译就会出现declaration may not appear after executable statement in block, 在keil中定义的变量声明不允许出现在语句之后,所以把int i,j;这句放在最前面。
