arduino for loop
The for loop in C is used to execute a block of code repeatedly for a specified number of times. It has three parts: initialization, condition, and increment/decrement. Here is an explanation of each step:
Initialization: This part is executed only once before the loop starts. It is used to initialize a variable that controls the loop. For example, you can declare and initialize a variable like "int i = 0;".
Condition: This part is evaluated before each iteration of the loop. If the condition is true, the loop continues; otherwise, it terminates. It is typically written as "i < n" or "i <= n", where 'i' is the loop control variable and 'n' is the number of times the loop should run.
Increment/Decrement: This part is executed after each iteration of the loop. It is used to update the loop control variable. For example, you can increment the variable using "i++" or decrement it using "i--".
Inside the for loop, you can write the code that needs to be executed repeatedly. This code block is enclosed within curly braces {}.
Here is an example of a for loop that prints the numbers from 1 to 5:
for (int i = 1; i <= 5; i++) {
printf("%d\n", i);
}
In this example:
- The initialization part is int i = 1;
, where we initialize the loop control variable 'i' to 1.
- The condition part is i <= 5;
, which checks if 'i' is less than or equal to 5.
- The increment part is i++
, which increments 'i' by 1 after each iteration.
- The code block inside the loop prints the value of 'i' using printf("%d\n", i);
.
The output of this code will be:
1
2
3
4
5
