Considering the given code as an algorithm calculate the time complexity of this code.

```
#include<iostream>
#include<stdlib.h>
using namespace std;
int main(){
int i, j, n;
for(i=0;i<n; i++){
for(j=0; j<n; j++){
cout<<"my time complexity is = "<<i*j<<endl;
}
cout<<"complexity is increasing"<<j<<endl;
}
system("pause");
return 0;
}
```
