Please convert the code to C Language

 

#include <bits/stdc++.h>
using namespace std;

//comparing goodness of hash function 1 &  2
int main()
{

    //set of input numbers
    vector<int> arr{ 12345, 234245, 1223123, 765845, 345234, 234534, 98675, 34523, 123, 3245 };

    //using hash function 1
    cout << "using hash function 1\n";
    for (int a : arr) {
        cout << a << "->" << to_string(a).length() % 10 << endl;
    }

    //using hash function 2
    cout << "\n\nusing hashh function 2\n";
    for (int a : arr) {
        cout << a << "->" << (rand() * a) % 10 << endl;
    }

    return 0;
}
