Description

Uses bubble sort to sort an integer array

Demo Code

#include <cstdlib>
#include <iostream>
#include <ctime>

const int limit = 10;

int main(int argc, const char *argv[]) {

  srand(time(0));//from  w w w. ja v  a 2 s.c o  m

  int n[limit] = {};

  // randomise elements of n
  for (int i = 0; i < limit; ++i) {
    n[i] = rand() % 100;
  }

  std::cout << "Unsorted array n: " << std::endl;
  // print unsorted array
  for (int i = 0; i < limit; ++i) {
    std::cout << n[i] << std::endl;
  }

  // BUBBLE SORT
  for (int i = 0; i < limit - 1; ++i) {
    for (int j = 0; j < limit - 1; ++j) {
      if (n[j] > n[j + 1]) {
        int temp = n[j];

        n[j] = n[j + 1];
        n[j + 1] = temp;
      }
    }
  }

  for (int i = 0; i < limit; ++i) {
    std::cout << n[i] << std::endl;
  }

  return 0;
}
