Problem Statement - Checking for valid Identifiers

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;

Solution

TC++ #1782

Valid Identifiers are:
argument
amar_is_a_beautiful_boy

 

Invalid Identifiers are:
c#  (# is not allowed)
taj mahal (space between words is not allowed. they can be separate identifiers if separately declared)
break (keyword can not be used as identifier)
file.ext (. is not allowed in the identifier)
