Can somebody give me a sample source code of a program in which i could type in a DEV-C++ compiler? TY!?

Answer 1

#include
#include
using namespace std;

int isPrime( long n) {

int i,k;
if (n<2) return 0;

k=(int)sqrt(n);
for (i=2; i<=k; i++){
if ((n%i) != 0 ) continue;
return 0;

}
return 1;
}

int main() {

long i,a,b;

do {
system("cls");

cout <<"\n\nEnter two numbers : ";
cin >> a >> b;

if (a > b) swap(a,b);

cout <<"\n\nThe prime numbers between ( and \n";
cout << " including ) "<< a << " and " << b << " are : \n\n";

for (i=a; i<=b; i++) {
if (isPrime(i)==1) printf("%d ,",i);
}

cout << "\n\n";
system("pause");
} while (1 != 2);

return 0;
}
