Please correct my code

#1

#include <bits/stdc++.h>
using namespace std;
#define ll long long int

int primefactor(int n)
{
int i,j=0,count;
vector<pair<int,int>>factor(10000);

for(i=2;i*i<=n;i++)
{
    if(n%i==0)
    {
        count=0;
        while(n%i==0)
        {
            n=n/i;
            count++;
        }

        factor[j]=make_pair(i,count);
        j++;
    }
}

if(n!=1)
{
    factor[j]=make_pair(n,1);
    j++;
}

return factor;

}

int main()
{
ios_base::sync_with_stdio(false);
cin.tie(NULL);

int n,i,j=0,count;
cin>>n;

vector<pair<int,int>>factor2(10000);

factor2=primefactor(n);

for(i=0;i<j;i++)
{
    cout<<factor[i].first<<"^"<<factor[i].second<<" ";
}


return 0;

}

Hey,
You’ve to mention the return type of the function as vector<pair<int, int>> instead of int, that’s where the error is.
