Is the following declaration valid?

int var, var;

Explanation & Hints:

No, the declaration int var, var; is not valid in C (and most other programming languages) because it attempts to declare the same variable var twice in the same scope. This results in a compilation error due to the redefinition of the variable name. Each variable in a given scope must have a unique identifier.
