Is possible to use a for loop in place of a while loop?
Yes, it's easy:Old: while (expression)statementNew: for (; expression;)statement
For loop -uses?
You can use a for loop whenever you can use a while loop; it's the same.
How you can use while loop in place of select case?
While is NOT a replacement for SWITCH -- CASE However , still if this is the requirement then , you can do this : While (1) { if (case1 ) {} if (case2 ) {} : : : if (case n ) {} if (case default ) {} } //end of while loop
Why you need a for loop when you have already while loop or do while loop?
We need a for loop because the while and do-while loops do not make use of a control variable. Although you can implement a counter inside a while or do-while loop, the use of a control variable is not as self-evident as it is in a for loop. Aside from the use of a control variable, a for loop is largely the same as a while loop. However, it is quite different to a do-while loop, which always executes at least one iteration of the loop before evaluating the conditional expression. In a for and while loop, the conditional expression is always evaluated before entering the loop, which may result in the loop not executing at all.
When should use a while loop over a do loop?
Generally speaking a for loop looks like this:for(Initialization;condition;increment){Do Stuff}whereas a while loop looks like this:while(condition){Do Stuff}Before the while loop there should be some initialization and somewhere in the Do Stuff section there should be statements that change the condition. Those statements are analogous to the increment section of the for loop.
Why you use for loop inside switch statement?
Because you have to repeat something. (Or you can use while-loop, too.)
What type of loop use a Boolean expression to control the number of times that it repeats a statement set of statements?
A counted loop. Typically we use a for loop for counted loops: // loop 10 times... for (int i=0; i<10; ++i) { // ... } We can also use while and do-while loops to do the same thing, however a for loop provides all the information up front where it belongs and we can localise the control variable. With while and do-while loops, the control variable must be declared outside the loop, and the increment is usually specified at the end of the loop. This makes while and do-while loops harder to read because the information that controls the loop is separated: // loop 10 times... int i = 0; while (i<10) { // ... ++i; } A do-while loop is similar to a while loop, but the control expression is placed at the end of the loop thus the loop always executes at least once. This also upsets the logic of a counted loop because the control variable is off-by-one. // loop 10 times... int i = 0; do { // ... ++i; } while (i<11);

1) use for loop 2) do while loop
How do you use switches in c?

What is the difference between while dowhile?
While: If we can use while statement it will check the condition then proceed further loop statement.DoWhile: If we use dowhile, first execute loop statement then check the condition.
The Do-While loop is what type of loop?
The do loop is similar to the while loop, except that the expression is not evaluated until after the do loop's code is executed. Therefore the code in a do loop is guaranteed to execute at least once. The following shows a do loop in action: do { System.out.println("Inside do while loop"); } while(false); The System.out.println() statement will print once, even though the expression evaluates to false. Remember, the do loop will always run the code in the loop body at least once. Be sure to note the use of the semicolon at the end of the while expression.
What is main different between do while and while?
If you want to execute a statement which is in while loop at least one time you can use do- while loop. this is why because initially first statements will be executed then condition will be checked. but in case of while first condition will be check then statements will be executed
