Both of these are loops used in the execution of various codes. But there is a fundamental difference between for and while loop in C, C++, Java. In this article, we will discuss the same. But let us know a bit more about each of these individually.
What is a for Loop?
The for loop provides its users with a concise way in which they can write the loop structure. The for statement, unlike the while loop, provides a very easy to debug and short looping structure. It does so by consuming the condition, initialization, and decrement/ increment in one line.
What is a while Loop?
The while loop is a type of continuous flow statement that basically allows the repeated execution of a code on the basis of any given Boolean condition. You can think of a while loop to be a repeating if statement.
Difference Between for and while Loop in C, C++, Java
Here is a list of the differences between for and while Loop in C, C++, Java.
Parameters | for Loop | while Loop |
Basics | The for loop provides its users with a concise way in which they can write the loop structure. It provides a very easy to debug and short looping structure. | The while loop is a type of continuous flow statement that basically allows the repeated execution of a code on the basis of any given Boolean condition. |
Number of Iterations | These must be known when using a for loop. | The while loop works well even if the number of iterations is basically unknown. |
Condition | It is a form of relational expression. | The condition, in this case, may be a non-zero value or an expression. |
Initialization | The initialization may exist both- outside the loop or in the loop statement. | The initialization, in this case, always occurs outside the loop. |
Time of Increment | The increment occurs only after the execution of the statement(s). | We can perform the increment both- after or before the execution of the given statement(s). |
Use | We use the for loop when the increment and initialization are very simple. | We use the while loop in the case of a complex initialization. |
