C++ Program to Insert an Element in an Array
Here is the C++ program to insert an element in an array. The array must be in ascending order. For example the array is 1 4 6 7. We have to insert 5. Then the resultant array will be 1 4 5 6 7. The program is given below. C++ Program to Insert an Element …
Stack in C++ Using Linked List
Here you will learn about stack in C++ using a program example. Stack is an abstract datatype which follows Last In First Out (LIFO) principle. Basically stack has two operations namely push and pop. push: inserting an element at the top of the stack pop: removing an element from the top of the stack Below …
