Can someone help me?Could someone help me write this Random10Numbers function?

Question

Why this code can only output two lines of random numbers? I want to generate four lines, each line contains ten and the single line of random numbers does not repeat

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int index = 0;
int counter[10] = {0};
int count = 1;
void Random10Numbers(int *numbers,int size){

int random_num;

if(count == size + 1){
count = 0;
index = 0;
for(int i = 0;i < size;i++){
counter[i] = 0;
numbers[i] = 0;
}
}
do{
random_num = rand() % 10;
}while(counter[random_num]);
counter[random_num]++;

numbers[index++] = random_num;
count++;

}
int main(){
srand(time(0));
int data[10];
int i,j;
for(i=0;i<4;i++){
for(j=0;j<10;j++){
Random10Numbers(data,10);
printf("%d ",data[j]);
}
printf("\n");
}
return 0;
}
