Random Array c++

i want to generate a random array number int, this array must to have 20 dimension; i tried to get it in this way:

#include <iostream>
#include <ctime> 
#include <cstdlib> 
using namespace std;
int main(){
int xRan;
srand( time(0)); 
xRan=rand()%90+1; 
int v1[20];  
for(int k=0; k < 10; k++){
v1[k]= xRan;
cout <<"the random array is "<<v1[k]<<endl;
}

In this way i obtain only an int in every position of the array, how i can obtain my full position random array? thank you in advance.
