Write a program to reverse a number in c using for loop

If the file does not exist, fopen returns NULL. If the file exists, its contents are overwritten.

Write a program to reverse a number in c using for loop

Enter these lines separately in the Shell. As in the simpler applications of range, the values are only generated one at a time, as needed.

To see the entire sequence at once, convert the sequence to a list before printing: It is needed when the step size from one element to the next is not 1. The most general syntax is range startpastEndstep The value of the second parameter is always past the final element of the list.

Each element after the first in the list is step more than the previous one. Predict and try in the Shell: The step size can be negative.

Try in the Shell: Make up a range function call to generate the list of temperatures printed in the tea example, Test it in the Shell.

These ranges, like the simpler ranges that we used earlier, are most often used as the sequence in a for loop heading: Obviously they could have been rewritten with range function calls. Now lets try a more interesting example. Suppose you want to let a user enter a sequence of lines of text, and want to remember each line in a list.

This could easily be done with a simple repeat loop if you knew the number of lines to enter. For example, in readLines0.

C++ Program to Reverse a Number

This means the number of repetitions would not be known ahead of time. A while loop is appropriate here. There is still the question of how to test whether the user wants to continue.

An obvious but verbose way to do this is to ask before every line if the user wants to continue, as shown below and in the example file readLines1. Read it and then run it: Note The data must be initialized before the loop, in order for the first test of the while condition to work.

Also the test must work when you loop back from the end of the loop body. This means the data for the test must also be set up a second time, in the loop body.

It is easy to forget the second time! Two lines must be entered for every one you actually want!Program to find reverse of a number in C++ is used to reverse a given number using for loop and finally prints the reversed number.

Related: Reverse of a Number using For loop in C. Working: First the computer reads a number from the user. We will take a loop and divide number from 2 to number/2.

This program takes an integer input from the user. Then the while loop is used until n!= 0 is false. In each iteration of while loop, the remainder when n is divided by 10 is . What is pseudocode. Pseudocode, like step-form, is a written way of stating algorithms but uses a much more restricted vocabulary. It is very much like a 3GL and for many programmers and program designers is the preferred way to state algorithms and program specifications. In C programming, file is a place on your physical disk where information is stored. Why files are needed? When a program is terminated, the entire data is lost.

If the number is not divisible by any of the numbers then we will print it as prime number. C++ Program to Reverse a Number. Reverse of number means reverse the position of all digits of any number.

For example reverse of is This code is write using for loop, modulus operator, if condition statement. align-content Specifies the alignment between the lines inside a flexible container when the items do not use all available space align-items Specifies the alignment for items inside a flexible container.

Using newlines in sed scripts. Occasionally one wishes to use a new line character in a sed script. Well, this has some subtle issues here.
