Question

Create a program on C++ for finding all primes number between two values (inclusive) as sample below

Sample Input	Sample Output
1 10	2 3 5 7
11 20	11 13 17 19
30 40	31 37

NOTES: Please use ARRAY. please show me the code & results. the result must be exactly the same as above, no additional sentences or other stuff. thank you very much

Answer 1

Explanation:

here is the program which expects 2 numbers entered by the user and then in that range, it checks whether each number is a prime number or not.

And then all the prime numbers are printed on the screen.

Code:

#include <iostream>

using namespace std;

int main()
{
int a, b;
cin>>a>>b;
  
for (int i = a; i <=b; i++) {
  
int is_prime = 1;
  
for (int j = 2; j<i; j++) {
  
if(i%j==0)
{
is_prime=0;
}
}
  
if(i==1)
{
is_prime=0;
}
  
if(is_prime==1)
{
cout<<i<<endl;
}
}

return 0;
}

output:
