You use a break statement to end execution of the enclosing iterator (loop) or switch statement. If omitted at the end of a case label, execution continues to the next case label, including the default case, until a jump statement is encountered (break, goto or return) or the switch statement falls from scope. Sometimes this can be desirable behaviour, thus the use of break is optional. A break statement is always optional at the end of the default case, or the last case label.
Its usage in loops is always optional, to allow a loop to end prematurely regardless of the conditional expression that controls the loop.

What is the purpose of Continue and break statement in C?
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

Syntax:if (expression)statement;[elsestatement;]The expression must evaluate to a boolean value, where zero is false and all non-zero values are true.

If an else statement is provided, it is only executed when the expression evaluates false. After the appropriate statement is invoked, execution passes to the statement that immediately follows the entire if statement.
