Write a function that receives two numbers as an argument and display all prime numbers between these two numbers. Call this function from main( ).
Source Code
#include<iostream>
using namespace std;
void showprime(int, int);
int main()
{
int x,y;
cout<<"Enter first number : ";
cin>>x;
cout<<"Enter second number : ";
cin>>y;
showprime(x,y);
return 0;
}
void showprime(int a, int b)
{
bool flag;
for(int i=a+1;i<=b;i++)
{
flag=false;
for(int j=2;j<i;j++)
{
if(i%j==0)
{
flag=true;
break;
}
}
if(flag==false && i>1)
cout<<i<<endl;
}
}
Output
Enter first number : 15 Enter second number : 70 17 19 23 29 31 37 41 43 47 53 59 61 67
