    int vet[1000], fre[50];
    int i;

    srand(time(NULL));

    for(i=0;i<1000;i++){
        vet[i]=(rand()%51);
    }

    for(i=0;i<1000;i++){
        printf("%d\n", vet[i]);
    }

    for(i=0;i<1000;i++){
        fre[vet[i]]=fre[vet[i]]+1;
    }

    for(i=0;i<51;i++){
        printf("The number %d  was generated %d times\n", i, fre[i]);
    }
