What is the difference between while loop and for loop in c computer language?

Answer 1

For while loop you have to define conditions for the loop in loop's body. In, "for loop" case it's more natural and comportable. For loop is good for numeric simulations in other words when you are using only numbers. Loop while is very good for symbolic conditions, for instance, to check the condition that char1 == char2;

Answer 2

In C++, a for loop allows you to (optionally) perform several operations in a single statement, including instantiating and initialising one or more variables, evaluating an expression before each iteration, and performing one or more operations at the end of each iteration. If the expression evaluates false, the loop terminates. Any variables instantiated within the for statement will fall from scope when the loop terminates.

A while loop only allows an expression to be evaluated at the start of each iteration. If the expression evaluates false, the loop terminates. Any variables used by the expression remain in scope when the loop terminates.

A do-while loop is similar to a while loop except the loop always executes at least once and the expression is evaluated at the end of each iteration, terminating the loop when it evaluates false.
