Introduction to Loops
Learn the loops for a fixed number of iterations in C++.
Repetition
The repetition of an instruction or a group of instructions is a commonly encountered phenomenon in programming. It is called a loop. As an example, let’s say we want our program to perform the following tasks:
- To read a document or data file line by line repeatedly until the end of the file
- To draw an image pixel by pixel, repeatedly using color values that show it on the screen
- To iterate through a collection of variables one by one to process their values
- To compute a result by applying a formula to several values
