How to print composite numbers that are consecutive

Question

For example, 24 ,25 ,26 ,27 and 28 are all composite numbers and also consecutive

Answer 1

The answer:

for(i=1;i<=n;i++){
for(j=i;j<=i+5;j++){
c=ob.compcheck(j); \\Use function compcheck() to check for composite no.
if (c==1) \\ 1 means composite no.
k++; }
if (k>=2)
on.disp(i ,k); \\ Use function disp() to display that follow the no.
}

That's all!!!
