How do you change a for loop to a while loop in C?

How do you change a for loop to a while loop in C?

To convert a for loop to while loop we need to simply add the initialization statement before the while loop.

  1. /* For loop */ int i; for(i = 0; i < 10; i++) { }
  2. /* While loop */ while(*str++ != NULL) { length++;
  3. /* Do while loop */ do. { status = check_connection();
  4. /* For loop */ int i; for(i = 0; i < 10; i++) {

Can you convert a for loop to a while loop?

You can always convert a for loop to a while loop. You can always convert a while loop to a for loop. The elements inside the for loop control are separated using semicolons instead of commas. You can always convert a switch statement to an equivalent if statement.

Which loop is faster in C?

Some situation, we can use while loop or do-while loop interchangeably. One of my friend told me that such situation we should use do-while loop. Because it is faster than while.

How do you convert a while loop to a for loop?

The variable you want to use in while loop is to be initialized first and then you can use it in the while loop and write the body of your loop then decrement/increment the variable accordingly….A for loop has this form:

  1. for( initialization; condition; increment/decrement )
  2. {
  3. set of statements;
  4. }

How do you do a while loop in Java?

The Java do-while loop is used to iterate a part of the program repeatedly, until the specified condition is true. If the number of iteration is not fixed and you must have to execute the loop at least once, it is recommended to use a do-while loop….Syntax:

  1. do{
  2. //code to be executed.
  3. }while(true);

How to convert for loop into while loop?

There are some little differences when using continue, but apart from that, this is the general bijective conversion: so the conversion is the same as the one suggested by @user2233706. Anyway, the original code is terrible for a long set of errors.

Why is the result of a while loop weird?

The while loop only doubles it. You are incrementing i with one and multiplying i by 2 in each iteration of your loop. This is the reason you are getting weird result. Try the following code for the same result as while loop is generating. Thanks for contributing an answer to Stack Overflow!

Do you need to initialize I in the DO WHILE LOOP?

The way you were doing it in the do – while loop, i was set to 2 before the total addition. If you haven’t done so in a previous portion of the code, you need to initialize i in the do…while. Also, in the do…while, change the order to have total incremented before i is incremented. Your code is incorrect.
