use of uninitialized value in numeric eq

This error message is typically encountered when attempting to compare a variable that has not been initialized or assigned a value to a numerical value using the "==" operator. In Perl, variables that are not initialized or assigned a value are assigned a default value of "undef", which is not a numerical value.

To resolve this error, ensure that the variable is initialized or assigned a numerical value before attempting to compare it using the "==" operator. You can also use the "defined" function to check if a variable has been initialized before attempting to use it in a numerical comparison.
