Searching in a vectors

Sample Code:

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

using namespace std;


void  createVect(vector<int> &vect)
{
    srand(time(NULL));
    for(int i = 0; i < 100; i++)
    {
        vect.push_back(rand()%100 + 1);
    }

}

int searchVect(vector<int> vect, int searchValue)
{
    int found = -1;
    //Manual Search
    for(int i=0;i<vect.size();i++)
    {
        if (vect[i]  == searchValue)
                    return i;
    }
    //Using Vector function
    found = vect.at(searchValue);
    return found;
}

int main()
{
    vector<int> int_vect;
    int num, found;
    createVect(int_vect);
    cout << "Enter the number to be searched"<< endl;
    cin >> num;
    found = searchVect(int_vect, num);

    if (found == -1)
        cout << num  << " is not found" << endl;
    else
        cout << num << " is found at " << found << "Location"<< endl;
    return 0;
}
