A break is a jump statement that allows code to exit a statement block without processing the remaining instructions in that statement block. Execution continues with the statement following the statement block.
Jump statements (the break, return, continue and goto keywords) are typically used in conjunction with a conditional expression, to allow execution to branch to another section of code within the same function whenever the expression is true. Function calls do a similar type of thing, branching off to other sections of code, but execution always returns to the point the call was made. Jump statements do not.
However, jump statements are also used in conjunction with switch statements. If a case label does not have a jump statement before the next case label is encountered, execution will fall through to the next label (just as as if that label did not exist). Sometimes this may be the intention but, in most cases, once a specific case has been handled, execution is normally passed to the statement immediately following the switch block, in which case a break is required (return and goto can also be used to exit a case label, but not continue). The final case (or default case) does not require a break if execution is expected to fall through to the statement following the switch statement.
With regards to the other jump statements:
The continue statement is used in loops, to start a new loop without executing any remaining command in the loop. In do..while() loops, execution is passed to the while(condition) expression.
The goto statement jumps to a given label, which must be present somewhere within the same function. A label is a user-defined name followed by a colon, marking the point in the function the goto will jump to.
The return statement exits a function altogether, returning control back to the calling function.
The break statement is used to exit the nearest enclosing scope. Control passes to the first statement that comes after that enclosing scope.
It's easy: there are no commands in C, but a few statements (such as: expression, if, else, switch, while, do-while, for, break, continue, return and goto), and countless library functions (like printf, malloc and fopen).
They are 'statements' to speak strictly, they are: , , if, else, while, for, do, return, switch, break, continue, gotoNote: is zero or more statements between '{' and '}'
All statements must be terminated with a semi-colon in C.
C provides two sytles of flow control:BranchingLoopingBranching is deciding what actions to take and looping is deciding how many times to take a certain action. Branching: Branching is so called because the program chooses to follow one branch or another.if statementThis is the most simple form of the branching statements. It takes an expression in parenthesis and an statement or block of statements. if the expression is true then the statement or block of statements gets executed otherwise these statements are skipped.? : OperatorThe ? : operator is just like an if ... else statement except that because it is an operator you can use it within expressions. ? : is a ternary operator in that it takes three values, this is the only ternary operator C has.switch statement:The switch statement is much like a nested if .. else statement. Its mostly a matter of preference which you use, switch statement can be slightly more efficient and easier to read. Using break keyword:If a condition is met in switch case then execution continues on into the next case clause also if it is not explicitly specified that the execution should exit the switch statement. This is achieved by using break keyword. Try out given example Show ExampleWhat is default condition:If none of the listed conditions is met then default condition executed. Looping Loops provide a way to repeat commands and control how many times they are repeated. C provides a number of looping way. while loopThe most basic loop in C is the while loop.A while statement is like a repeating if statement. Like an If statement, if the test condition is true: the statements get executed. The difference is that after the statements have been executed, the test condition is checked again. If it is still true the statements get executed again.This cycle repeats until the test condition evaluates to false. for loopfor loop is similar to while, it's just written differently. for statements are often used to proccess lists such a range of numbers: do...while loopdo ... while is just like a while loop except that the test condition is checked at the end of the loop rather than the start. This has the effect that the content of the loop are always executed at least once. break and continue statements C provides two commands to control how we loop: break -- exit form loop or switch.continue -- skip 1 iteration of loop.
The break statement is used to exit a loop or switch-case.
The break statement is used to exit the nearest enclosing scope. Control passes to the first statement that comes after that enclosing scope.

Only one: expression. Yes, in C expression is one of the statements. Some other statements are: if, do, goto, while, for, switch, break, continue, return, NULL-statement, compound-statement.

Decision making statements make use of conditional expressions. In C++ there are three possibilities: if/else, switch/case and the ternary operator (?:).
All statements must be terminated with a semi-colon in C.
Not sure what you mean by this question - using the exit call will exit a C program:exit (0) ;
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
