Use Dynamic Memory Allocation to Create an Array of Structs in C++ In scenarios where the size of the array needs to be determined at runtime or when working with a large number of elements, dynamic memory allocation provides an effective solution. ...
One of the ways to resize a dynamic array in C++ is by using theresizemethod. Theresizemethod is a built-in function of thestd::vectorclass in C++. It allows us to modify the number of elements contained within the vector, either by expanding or shrinking it. ...

Lastly, we have the variable name of type string, meaning it can store a string value/ character array. Next, as mentioned in the code comments, we use the cout statement to display the value of the age variable. Since the variable is not yet initialized, it holds a garbage value (assi...

However, you’ll rarely need to run the preprocessor by itself. 在Unix上,C预处理器的名称是cpp,但你也可以使用gcc -E来运行它。然而,你很少需要单独运行预处理器。 15.1.3 Linking with Libraries(链接库) The C compiler doesn’t know enough about your system to create a useful program all by ...
http://www.learncpp.com/cpp-tutorial/125-the-virtual-table/ To implement virtual functions, C++ uses a special form of late binding known as the virtual table. The virtual table is a lookup table of functions used to resolve function calls in a dynamic/late binding manner. The virtual ...

we need a libc leak so we can find its address in libc. Fortunately, the dynamic linker will place function pointers for resolved imports in the main binary's.got.pltsection. Those pointers are at a static address, so if we had an arbitrary read, we could get a libc leak (andsystemad...
