In the stack data structure, we can only push and pop the data through one end. It means that it is only accessed through the top, not through the middle or bottom. This is a very important feature of the stack.
A type of control structure that repeats a statement or set of statements is known as iterative, repetitive, or looping structure. There are multiple types of loops in C++. For example, while, do-while, and for loop.
The basic definition of for loop is that it executes one or more statements a specified number of times. It is also known as counter control loop. The for loop is used when you know the fixed number of iterations.
