What kinds of data structure are used to implement loop and iteration?

---

Loop refers to the code... iteration refers to the process in which the content of loop is executed once.. so 1 iteration refers to 1 time execution of loop.. so basically one loop can undergo many iterations..

---

loop is used for fixed no. of element or certain condition occurs while iterator is used for itearing element dynamically that have different no. of elements at runtime

---

Only such of kind 1.

Some have tried using data structures of kind 42 for this purpose, but failed miserably.

---

Iteration is simply the number of time/times a loop can be executed, while loop is the code which generate or causes expressions to be iterated iteration when the loop is executing.

An example of lines of code in c++:

for(i=1; i<=10; i++)
   {
   cout<<"this is printed 10 times";
   }

The above code is a for_loop in which the execution of the statement "this is printed 10 times" will be iterated/repeated 10 times.
