The NEXT statement marks the end of an iteration and passes control back to the FOR statement to begin a new iteration.
Consider the following:
FOR n=a TO b STEP s
...
NEXT n
The 'a TO b' defines the range of values that will be assigned to n, starting with a. Each time the NEXT statement is encountered, n is incremented by s. If n is still within the bounds of the closed range [a:b], the loop performs another iteration, otherwise control passes to the statement that follows the NEXT statement.
A FOR - NEXT loop sets up a process that automatically performs a function several times. eg. FOR J = 1 TO 100 Will set a counter that will count up to 100 times. After this command you program a function or several functions. When the lines of code have been operated on, the end of the sequence is terminated, with the command NEXT. This will automatically add one to the counter and return to the start of the FOR J =1 to 100 line. If by adding one to the counter exceeds 100, then the program will skip over the NEXT command and drop down to the next command.
The break statement exits out of the smallest containing loop or switch-case statement. The continue statement transfers control to the next iteration of the smallest containing loop statement.
Break is used to exit the closest loop. Continue will cause the program to go to the beginning of the loop. for(int x=0;x<10;x++) { //continue; for(int y=0;y<10;y++) { break; } } The break statement causes the inner loop to stop at the first iteration. If the continue statement was uncommented, the inner loop would never be executed because the program would jump back to the beginning(until x = 10 of course).
int i;for (i=10; i
Break statements:-its terminates the current while or for loop and continue the program execution from the statement following the terminated.NOTE:-note that it is wmlscript syntax error to use the break statement outside of while or a for statements.example;Breakstatement:Break;Continue statement:-this statement terminate execution of a block of statementin while or for loop and continues execution of loop with the next iteration.note that the continue statement does not terminate the execution of loop and also is wmlscript syntax error to use the break statement outside of while or a for statements.-> in while loop, it jumps back to the condition.-> in for loop,it jumpsto the update expression.syntax:continuestatement:continue;
The continue statement skips the remaining statements in the current iteration and execution proceeds with the iteration control statement for the next iteration.
the test condition will be checked first after wards the body of the loop will be excuted in while statement and the the do while statement represented the body of the loop will be executed first and then the test condition will checked next
In continue statement, we immediately continue next step through loop In go to statement, we go to in perfect label which we call.
A for loop is classified as an iteration statement. A simple example might be... For x = 1 To 10 'loop body Next x The same loop expressed as a while loop (classified as a control flow statement) could be... x = 0 Do While x < 11 'loop body x = x + 1 Loop .
loop within in a loop is called for next loop
A while loop evaluates a conditional expression at the start of each iteration. If the conditional expression evaluates false, execution passes to the statement that immediately follows the body of the loop. If the conditional expression evaluates true, the body of the loop executes one iteration. When the end of the loop is reached, or a continue statement is encountered within the body of the loop, control passes back to the while statement where the conditional expression is re-evaluated. If a break statement is encountered within the body of the loop, the loop terminates and control passes to the next statement. If a return statement is encountered within the body of the loop, the loop terminates and control passes to the calling function.while (expression) {// repeats until the expression evaluates false}The braces are optional when the body of the loop is a simple statement. Compound statements must be enclosed in braces.A flag-controlled while loop has a simple conditional expression that evaluates a Boolean value:bool x;// ...while (x==true) { // flag-controlled loop// ...}}The above loop can also be written without the equality operator:while (x) { // flag-controlled loop // ...}Moreover, any integral type (such as int or char) will implicitly convert to a bool such that non-zero values evaluate true and zero evaluates false. As such, any integral type can be used in a flag-controlled loop.
Break - will force to terminate the loop you are in to the nearest outer block.Continue - will force to skip the rest of the code in loop and take next iteration.Break for example is not only limited to loop constructions, it is also used in switch statement in order to stop executing following cases (works as described above, jumps out of switch).
