Question

Odd even number printing using thread I came across this question and wanted to discuss solution in C++ . What I can think of using 2 binary semaphores odd and even semapho

Answer 1

This is the easiest solution you can refer:

#include
#include
#include
#include
int count=0;
using namespace std;
mutex m;
void* printEven(void *a)
{
   while(1)
   {
       m.lock();
       if(count%2==0)
       {
          cout<<" I am Even"<100)
          break;
       m.unlock();
    }
 }
 int main()
 {
     int *ptr = new int();
     pthread_t thread1, thread2;
     pthread_attr_t attr;
     pthread_attr_init(&attr);
     pthread_create(&thread1,&attr,&printEven,NULL);
     pthread_create(&thread2,&attr,&printOdd, NULL);
     pthread_join(thread1,&ptr);
     pthread_join(thread2,&ptr);
     delete ptr;
 }
