C program for Palindrome Number using do-while Loop.
Most statements in a typical C program are simple statements of this form. Other examples of simple statements are the jump statements return, break, continue, and goto.A return statement specifies the return value for a function (if there is one), and when executed it causes the function to exit immediately. The break and continue statements jump immediately to the end of a loop (or switch.
When we write any loop statement within the another loop statement then that structure is called as nested loop. We have already seen all the loops statements ( while loop, do.while loop, for loop ).
Control then returns back to the top of the while statement. 1 10 evaluates to true, so the code block is executed again. The code block will repeatedly execute until count is 10, at which point 10 10 will evaluate to false, and the loop will exit. It is possible that a while statement executes 0 times. Consider the following program.
A while statement is similar to an if statement in that a conditional expression is evaluated and, if that expression evaluates true, the body of the statement is executed otherwise control passes.
A do while loop is a control flow statement that executes a block of code at least once, and then repeatedly executes the block, or not, depending on a given condition at the end of the block (in while). When use do.while loop. when we need to repeat the statement block at least one time then use do-while loop. In do-while loop post-checking.
The goto statement:- C supports the goto statement to branch unconditionally from one point to another in the program. The goto requires a label in order to identify the branch is to be made. A label I any valid variable name, and must be followed by a colon. The label is placed immediately before the statement where the control is to be transferred. Syntax: Goto label; ----- ----- label.
The easiest way to think of the loop is that when it reaches the brace at the end it jumps back up to the beginning of the loop, which checks the condition again and decides whether to repeat the block another time, or stop and move to the next statement after the block. DO.WHILE - DO.WHILE loops are useful for things that want to loop at.
