What is a for loop iteration?

A for loop is a repetition control structure which allows us to write a loop that is executed a specific number of times . The loop enables us to perform n number of steps together in one line. In for loop, a loop variable is used to control the loop.

“i” is a temporary variable used to store the integer value of the current position in the range of the for loop that only has scope within its for loop . You could use any other variable name in place of “i” such as “count” or “x” or “number”.

In computer science, a for-loop (or simply for loop) is a control flow statement for specifying iteration, which allows code to be executed repeatedly . Various keywords are used to specify this statement: descendants of ALGOL use “for”, while descendants of Fortran use “do”.
