这个是C++标准的警告 在C里面这么写是没问题的 但是C++不建议你这么写 而且main函数在C++标准中应该是一个int类型的函数 最好是这么写 #include <stdio.h> int main() { printf("%d\n",NULL); return 0; }
是一个警告，可以忽略。如果非要修改的话，修改main函数 int main（）{ return 0；}
Return Values Thevoidkeyword, used in the previous examples, indicates that the function should not return a value. If you want the function to return a value, you can use a data type (such asint,string, etc.) instead ofvoid, and use thereturnkeyword inside the function: ...
