当您尝试访问定义范围之外的局部变量时,您会收到“variable not declared in this scope”错误,如上面的示例所示。 但是,如果您尝试访问定义范围之外的局部变量的地址,则会出现function returns the address of the local variable的错误。 这就是发生这种情况的原因。 我们知道,一旦函数完成执行,局部变量就会被销毁。
When a function returns a value, it is not related to memory: it has no address. Try: 12345678 #include <iostream> int f3() { return 2; } int main() { std::cout << "The address of the value returned by f3() is " << &f3() << '\n'; } Edit & run on cpp.sh that won...

针对用户的具体问题——“address of stack memory associated with local variable 'result' returned”,建议的解决方案是使用动态内存分配或通过参数传递来避免返回局部变量的地址。 使用动态内存分配的示例: c #include <stdlib.h> #include <stdio.h> char* createString(const char* text) { /...
