memory leak meaning code example

Example 1: memory overflow

In computer science, a memory leak is a type of resource leak that occurs when a computer program incorrectly manages memory allocations in a way that memory which is no longer needed is not released. A memory leak may also happen when an object is stored in memory but cannot be accessed by the running code.

Example 2: what are the causes of memory leaks in c

//If an exception is raised between allocation and deallocation, memory leak will occur.

void f1() {
    int* ptr = new int;

    // do something which may throw an exception

    // we never get here if an exception is thrown
    delete ptr;
}
