I typed

 int main()
 {
   cout<<\"Hello WOrld\";
   return (         


        

Answer 1

The following methods will solve your problem:

---

Method 1 : (BAD PRACTICE)

Adding the following line before main function.

using namespace std;

So your code will now become:

#include "iostream"

using namespace std;

int main(){
   cout << "Hello WOrld";
   return (0);
}

---

Method 2 : (GOOD PRACTICE)

You can simply write std::cout instead of cout.

Full code with std::cout

#include "iostream"

int main(){
   std :: cout << "Hello WOrld";
   return (0);
}

This tells the compiler that the cout identifier comes from the std namespace.

Method 2 is better than Method 1. Further reading : Why is "using namespace std" considered bad practice?
