Java has three types of loop control statements: for statement, while statement, and do statement. The following describes the
This error occurs because some Linux systems use Ash to compile shell scripts by default, as is my machine, but the scripts I write should be executed with bash. Although I noted in the beginning #!/bin/bash, as if it is still the default to find Ash, it is very frustrating. Search the internet for a bit, find two solutions: 1, modify script 2, modify the system default execution Shell toolThe first kind of practice is that the original for loop is si

In php, loop statements include many, such as for, foreach, while, do while, and goto statements. Below I will give you a brief introduction to the structure and usage of these loop statements.

}
Execution Process:
First, determine whether the relational expression is true or false.
Execute the statement body if it is true.
If it is false, the statement body is not executed.
