二十八、变量 "using" 不是类型名 试图在.c后缀名的文件中写C++代码,就会遇到这个错误 比如在"111.c"文件中有如下代码: #include<iostream> using namespace std; int main(){ ... } 那么它会在using上报错 把文件后缀名改成.cpp就好了 二十九、a function-definition is not allowed here before '{' to...
The compiler now supports this form of type deduction and, as a result, calls to function templates using initializer lists might now be ambiguous or a different overload might be chosen than in previous versions of the compiler. To resolve these issues, the program must now explicitly specify...

void f(void *); void h(void) { f(&__FUNCTION__); void *p = &""; } 要修复此错误,请将函数参数类型更改为 const void*,或者将 h 的正文更改为如下示例: C++ 复制 void h(void) { char name[] = __FUNCTION__; f( name); void *p = &""; } C++11 UDL 字符串 下面的代码现在...

内存管理是 C++最令人切齿痛恨的问题,也是C++最有争议的问题,C++高手从中获得了更好的性能,更大的自由,C++菜鸟的收获则是一遍一遍的检查代码和对 C++的痛恨,但内存管理在C++中无处不在,内存泄漏几乎在每个C++程序中都会发生,因此要想成为C++高手,内存管理一关是必须要过的,除非放弃 C++,转到Java或者.NET,他们的...
