Look into my code https://code.sololearn.com/cb2wiWxF6kG3/#cpp To fix your code replace prime function: void prime( int m, int n) { for( int i=m; i<n; i++) { if ( i == 1) continue; int f = 0 ; for (int p= 2 ; p<i; p++) { if(i%p== 0 ) f=1 ; } if(f== 0 ) cout << i << endl; } } or fix step by step: 1) add if ( i == 1) continue; - after line 6 to exclude 1 2) replace outer p with f - on line 8, 12, 14 3) fix condition p<m to p<i - on line 9 4) not necessary count p or f - on line 12
