Loop

Definition - What does Loop mean?

A loop is a programming function that iterates a statement or condition based on specified boundaries.
The loop function uses almost identical logic and syntax in all programming languages. Thus, a specific statement or a group of instructions is continuously executed until a specific loop body or boundary condition is reached. The result of the entire loop body’s first operation cycle serves as the next repetition’s starting point.

Techopedia explains Loop

A loop repeatedly executes code in its body until the loop conditional statement becomes false.

A loop is divided into two parts:

  • Loop Statement: This defines the time limit to be true for the continuous loop that is contingent on the attached conditional statement.
  • Loop Body: This holds the statement’s code or instruction; it is is executed with each loop cycle.


Here is an example of a loop (a for loop) in C#:

int i; 

string numbers = ""; 

for (i = 1; i <= 9; i++) 

    numbers += i.ToString(); 

Console.WriteLine(numbers);
The output of the example is: "123456789"
