In this blog post, we learn how to write a C program to find reverse of a number using recursion?Write a recursive function in C programming to find the reverse of a number. It also applies to the strings. What is Switch Case? Find the remainder using %, you will get the last digit of a number, r = num % 10. remainder is 1 then 10+2 , 120+3 , 1230+4 we get that number. Asking for help, clarification, or responding to other answers. Note: Though flowcharts can be useful for writing and analyzing a program, drawing a flowchart for complex programs can be more complicated than writing the program itself. If you're not treating it as a number, why not just read it as a string? Is it possible to raise the frequency of command input to the processor in this way? rev_Num=rev_Num*10+remainder; printf("Reverse of %d is %d",a,rev_Num); Here, we will create a function in the main method and use the algorithm inside it to calculate the reverse of the number entered by the user. Find the remainder using %, you will get the last digit of a number, r = num % 10. d = n% 10 R = r * 10 + d N = floor (n / 10) Step 5: Print reverse number r if the condition is correct. Not very hard or impressive enough to be copied. SET result = result * 10 + digit It has multiple pipelines per core and multiple cores. Lets find out. The algorithm starts by taking the string to be reversed as input from the user. @acheong87 Thanks. For example, 1 integer division can be as high as 40 cycles, so I guess this can be fast enough.

Note that d*10 + i is equivalent to i%10 but much faster since modulo is around 10 times slower than multiplication. . If the user provides the following input to the flowchart : 7836, The expected output of the flowchart is : 6387, START Then 36 = 2*2*3*3 60 = 2*2*3*5 GCD=2*2*3 i.e GCD=12 GCD is also known as HCF (Highest Common Factor) Algorithm for Finding GCD of 2 numbers: You can now try using the logic in different ways and create complex programs requiring reversing a number. Recursive procedure A recursive procedure call is a procedure call that calls the procedure itself. The WHILE loop terminates as the loop condition is evaluated to False. Algorithm to print the reversed number given by user? But how do we build the logic to make that happen through a program? Here, the '+'' operator performs the concatenation of the characters of the string in reverse order. . Write a program to reverse the digits of an integer. Hence, creating flowcharts for complex programs is often ignored. Ltd. All rights reserved. To store the reversed string, we are initializing a variable 'rev' as an empty string. Proper Documentation: Flowchart provides better and proper documentation. Example: What is 5! printf("\nEnter the number to reverse: "); printf("Reverse of %d is = %d\n", Num, Rev); Rev = Rev *10+ remainder; In this article, you have learned everything you needed to know about a C program to reverse a number.

In this program we will be using the concept of ones tens hundreds and thousand places place value system. Ravikiran A S works with Simplilearn as a Research Analyst. Noisy output of 22 V to 5 V buck integrated into a PCB. Let's see an example, Input : num . step 3: Read digit step 4: Check whether digit>0 then go to step 5 else go to step 9 step 5: reverse =reverse *10 step 6: reverse=reverse+digit%10 step 7: digit =digit/10 step 8: Go to step 4 . I tested it and it is about 25 % faster than other answers. WHILE number >= 1 If we took a number 4567 then the reverse of the number should be 7654. for example, 121 <-> 121 3663 <-> 3663 Above are the palindromic number. How to find reverse of a number in C programming using recursion. Assuming memory is accessed at 100 ns time or 200 cycles and integer is 7 digits on average, other solutions have these: if these make more than 100 nanoseconds / 200 cycles, then table would be faster. Then the while loop is used until n != 0 is false (0). The following codes help you to understand more about Reversing numbers, String and Array elements. Step 6: End Source Code: Display the reverse of a number in python Finally, the reverse variable (which contains the reversed number) is printed on the screen. Test this code Thanks for contributing an answer to Stack Overflow! Run the flowchart and verify the output of the flowchart. Find the largest among three different numbers entered by the user. In this loop, we are reversing the string, one character at a time by performing: rev = rev + character at position 'i'. Making statements based on opinion; back them up with references or personal experience. 2. rev = rev * 10 + r will append r to rev. The flowchart uses a recursive procedure to print the numbers in reverse order. I'm not sure if this is the most efficient way. Reversing it is then trivial. The logic is pretty simple to reverse a number, that is to get the extreme right digit of that number, multiply it with 10, add a remainder if any, and place it in the new reversed number. reverse*=10; reverse+=digit%10; digit/=10;} printf("\nThe Reverse is\t\t: %ld",reverse); getch();} Algorithm step 1: Start step 2: Intilize reverse=0.
