#include <iostream>

void sort(int *, int);

int main() {
int num_of_input = 0;
cout << "How many number do you want to enter? "; cin >> num_of_input;

int *inputs_container = new int[num_of_input];

for (auto i = 0; i < num_of_input; ++i) {
do { // check for valid input which is integer values
cout << "Value " << i + 1 << " is ";
cin >> inputs_container[i];

if (std::cin.fail()) {
std::cin.clear();
std::cin.ignore(200, '\n');
cout << "Enter correct value.\n";
}
else break;
} while(true);
}

sort(inputs_container, num_of_input);

for (auto x = 0; x < num_of_input; ++x) cout << inputs_container[x] << "\t";
cout << endl;

delete []inputs_container;
inputs_container = 0;
}

void sort(int *c, int size) {

/*** using selection sort to sorting the list ***/

int min; // holds the smallest element index
bool isSwap = false; // Auxiliary flag

for (auto i = 0; i < size - 1; ++i) {
min = i; // initialize with the first element of the container
for (auto j = i + 1; j < size; ++j)
// comparing each elements of the container and updating min
if (c[j] < c[min]) {min = j; isSwap = true;}
// swapping
if (isSwap) {
c[i] ^= c[min];
c[min] ^= c[i];
c[i] ^= c[min];
isSwap = false;
}
}
}
