Learn about Resource Acquisition Is Initialization (RAII) and smart pointers in C++. This article provides insights into memory management best practices in C++ programming.
Discover the various levels of pointers in C and C++. Learn how many levels you can use and their significance in programming.
C++ supports null pointer, which is a constant with a value of zero defined in several standard libraries. 2 Pointer Arithmetic There are four arithmetic operators that can be used on pointers: ++, --, +, - 3 Pointers vs Arrays There is a close relationship between pointers and arrays....
Now for Dynamic Memory Allocation,int* dynamicPtr = new int(30); Memory is dynamically allocated usingnewand initialized to 30, Where the address of this memory is stored in the pointerdynamicPtr. ptr = dynamicPtr;in this ptr is modified to point to the dynamically allocated memory (dynamic...
