Consider an integer in which each digit is either 0 or 1. Write a program to rearrange the digits such that all the 0s appear before the 1s. Output the resulting number. sample input: 01001010101 sample output: 00000011111
I think I'd try something like reading the user input into a char array, parsing the input string making sure it's either a 1 or 0, and if it is, process the string within a function. Code: char input[33] = { 0 }, *p; long result = 0; // read input; // validate input; // process input; result = strtol(input, &p, 2); // print result Before writing and testing the function, try strtol directly to make sure you get the expected result. Code: char *p; printf("%ld", strtol("01001010101", &p, 2)); Give it a try and post your code if you need any help. Good luck.
till now we at are not taught use of arrays,strings.we are just being taught loops,if & else statements,functions.

what you might try is a couple of int variables for counters - one for 1s and another for 0s. If you use getchar for the input loop, you should be able to determine the number of 1s or 0s by using input - '0'. After exiting the input loop, use the two counters in loops to print the respective 0s and then 1s.
