Write down identifiers and literals in the code given here.

int main()
{
  int a=5;
  cout<<"a="<<a<<endl;
  float b=3.5;
  double c=4.56;
  cout<<"b="<<b<<endl;
  cout<<"c="<<c<<endl;
  cout<<"Sum of a+b+c = "<<a+b+c<<endl;
  return 0;
}

Find the valid and invalid identifiers in the following piece of code segment.

int argument=123;
char c#='#';
float amar_is_a_beautiful_boy=3.45;
int taj mahal=1;
int break=0;
string file.ext="myfile.txt";
cout<<argument<<endl;
cout<<c#<<" "<<amar_is_a_beautiful_boy<<" "<<taj mahal<<endl;
cout<<break<<file.ext<<endl;
