int s[150][150],parent[150][150],i,j,l,n,loop;
public:

void css(void);
void density :: bd(void)
cout<<"ENTER THE POPULATION SIZE = ";
cin>>n;
cout<<"\nENTER THE NO.OF LOOPS = ";
cin>>loop;
for(i=0;i<n;i++)
for(j=0;j<80;j++)
s[i][j]=rand()%2;
cout<<"s:"<<s[i][j];
void density :: css(void)
int a,b;
float c;
for(i=0;i<n;i=i+2)
     b=rand()%100;
     cout<<"random b="<<b;
main()

d.bd();
d.css();
