The continue statement in Tipcontrol (and similar languages like C++) is used within looping constructs to skip the remaining code in the current iteration and proceed with the next iteration of the loop. It provides a way to control the flow by skipping over certain conditions or sections of the loop body.
Structure of the continue Statement
The continue statement is used inside loops like for, while, or dowhile:
Components:
- Loop Initialization and Condition: These setup and control the loop’s execution.
- Condition to Skip: A specific condition under which the rest of the loop’s current iteration should be skipped.
continueStatement: When encountered, control moves immediately to the next iteration, skipping any subsequent code in the loop block.
Simple Example
Here’s a basic example demonstrating the continue statement within a for loop:
// Loop through numbers 1 to 10 for (int i = 1, i <= 10, i+=1) { // Skip printing even numbers if (i % 2 == 0) continue; lib.log(“Odd number: “ + i); };
Explanation:
- Looping Construct: The loop iterates over numbers 1 to 10.
- Skip Condition:
if (i % 2 == 0)checks ifiis even. When the condition is true, thecontinuestatement is executed. - Effect of
continue: Thelib.logoperation is skipped for even numbers, and the loop jumps directly to the next iteration.
Practical Use
- Flow Control:
continueis handy for skipping specific iterations based on certain conditions without exiting the loop entirely. - Efficiency: Used to bypass costly operations within a certain condition, improving the loop’s execution efficiency.
The continue statement provides an efficient way to control loop execution by conditionally skipping over portions of the loop body, allowing focus on logic relevant to the iteration objective.
