Array element value Duplicate Elimination

Demo Code

#include <iostream>

void addToArray(int[], int);

const int limit = 20;

int main(int argc, const char *argv[]) {
    int n[limit] = {};
    int value;/*from w  w  w .  j a  v a 2 s  .  co m*/

    for (int i = 0; i < limit; ++i) {
        std::cout << "(" << i + 1 << "/20) Enter value between 10 and 100: ";
        std::cin >> value;

        if (value >= 10 && value <= 100)
            addToArray(n, value);
        else
            i--;
    }

    for (int i = 0; i < limit; ++i) {
        if (n[i] != 0) std::cout << n[i] << std::endl;
    }
    return 0;
}
// adds v to array if unique
void addToArray(int n[], int v) {
    static int limit = 0;

    bool duplicate = false;

    // no duplicates already in list so only need to compare to v not each other
    for (int i = 0; i <= limit; ++i) {
        if (n[i] == v) {
            duplicate = true;
            break;
        }
    }

    // no duplicate - add unique value and increase limit counter
    if (!duplicate) {
        n[limit] = v;
        ++limit;
    }
}
