example of random and randomize function in c++
void main()
{
randomize();
int k;
int vett[90];
clrscr();
for (int i=0; i<90; i++)
{
do
{
vett=random(90)+1;
k=0;
while (vett!=vett[k])
k++;
}
while(k!=i);
}
cout<<"?????????";
cout<<"\n";
for (int j=0; j<90; j++)
cout<<""<<vett[j]<<" ";
int tab[91];
int h;
int val;
int u=0;
for (int l=0; l<90; l++)
{
h=random(90-u);
val=vett[h];
vett[h]=vett[90-u];
tab[val]=val;
u++;
}
cout<<"\n";
cout<<"after ...........????";
cout<<"\n";
for (int y=1; y<91; y++)
cout<<""<<tab[y]<<" ";
getch();
}
