D) Error in real constant 10. Which of the following.compiler error gccurs) when same variable has been identified in 2 different types?) (A) Duplicate identifier Derleme Hotos B) Variable identifier expected C) Type mismatch D) Invalid file type types=Duplicate identifier

The correct answer is (A) Duplicate identifier error.<br /><br />When the same variable has been identified in two different types, it results in a compiler error known as a "duplicate identifier" error. This error occurs when the compiler encounters two different declarations for the same variable with different data types, which is not allowed in most programming languages.<br /><br />The error message "Duplicate identifier" indicates that the compiler has encountered a duplicate declaration for the same variable, and it cannot determine which declaration to use. This error can be resolved by either changing the variable name or using a different data type for the variable in one of the declarations.
