For reference comparison:

 # include 

Int isprime (int a) 
{
int i; 
If (a<=3) return a> 1; 
for(i=2; I * i<=a; I++) 
{
If (a % I==0) return 0; 
} 
return 1; 
} 

Int outprime (int z) 
{
Int j, CNT=0; 
For (j=2; J{
If (isprime (j)) 
{
Printf (" % 4 d ", j); 
Cnt++; 
If (CNT % 6==0) printf (" \ n "); 
} 
} 
} 

Int main () 
{
Int t; 
Printf (" please enter the number which you want to request within the scope of the prime number: "); 
The scanf (" % d ", & amp; T); 
Outprime (t); 

return 0;
