what is the purpose of the status in the C language?

In the C language, the status is typically used to represent the exit status or return status of a program. After the program has finished executing, the status can be used to check the program’s exit status, usually to verify if the program executed successfully, or if any errors or exceptional situations occurred. In the main function, an integer value can be returned to the operating system as the status using the return statement. It is commonly agreed that returning 0 indicates a normal program exit, while any other non-zero value typically indicates an abnormal program exit or error.
