Let's try to understand this through an example. . Based on the string and format code used, the method returns its equivalent datetime object. In order to create a stack in C++, we first need to include the stack header file. It first sorts elements that are far apart from each other and successively reduces the interval between the elements to be sorted. In this program, the elements are stored in the integer array data []. In this approach, the element is always searched in the middle of a portion of an array. Here, Type indicates the stack's type. To understand this example, you should have the knowledge of the following C programming topics: C if. The array can hold 12 elements.
