In computing, the "exit" command is typically used to terminate a program or a process, while the "close" command is used to shut down a file or a resource that is being used within a program.

The break statement is frequently used to terminate the processing of a particular case within a switch statement. Lack of an enclosing iterative or switch statement generates an error.Within nested statements, the break statement terminates only the do, for, switch, or whilestatement that immediately encloses it. You can use a returnor goto statement to transfer control elsewhere out of the nested structure.This example illustrates the break statement:#include int main() { char c; for(;;) { printf_s( "\nPress any key, Q to quit: " ); // Convert to character value scanf_s("%c", &c); if (c == 'Q') break; } } // Loop exits only when 'Q' is pressed
