19 C # loop statement skipping and interrupting continue and break,

 

In the C # loop statement, sometimes we want to skip a loop. Sometimes we want to terminate the entire loop directly when a condition is met. C # provides the continue and break statements for us.

The usage of continue is the same as that of break. Write this word directly and add a semicolon to it.

For example:

Continue;

Break;

These two statements can be used in both the while loop and for loop.

When a continue statement is encountered in a loop, the statements following this loop are no longer executed. Start to execute the next loop.

When a break statement is encountered in a loop, the entire loop is terminated directly. That is to say, not only does the current loop not run, but all the subsequent loops do not.

The continue and break statements are usually used in combination with the if statement.

 

You create a project. The solution name is Sloution19, the project name is Exercise19, and the project type is console program. Click Program. cs. Add the code to it.

Here is a brief explanation of the above Code.

1. When there are no break and continue statements, both the while loop and the for loop want to output numbers 1 to 10 in the dos window.

2. When I = 3 or j = 3, The if condition is true and the contiue statement is executed. The statement after continue is no longer executed. Start a new cycle. Note that all the statements before continue are executed.

3. When I = 7 or j = 7, the if condition is true and the break statement is executed. The statement after the break is no longer executed. The entire loop statement is terminated.

Exercise

1. Read this code and add comments to important statements.

2. Move the 17th lines of code to the 26th lines of code before braces. What is the result of running the program? What is the reason?

3. Try to write a piece of code and print an even number from 1 to 10 in a loop. Consider using continue.

4. Calculate 1 + 2 + 3 + .... If the sum is greater than 68, how many do we need to accumulate? Use break.
