In conclusion, the“bad operand type for unary ‘str'”error occurs when attempting to use a unary operator on a value of the wrong data type. Understanding the causes of this error and how to properly handle string operations can help you avoid this common issue in Python. We hope that ...
For example, a C programmer might need to write ⋆⋆p to dereference a variable declared as char ⋆⋆p;. We can add a dereference production for Value as well: Value→ ⋆ Value. The resulting grammar is still an lr(1) grammar, even if we replace the x operator in Term→ ...

The unary minus operator is used to negate a number, and when it is used before a variable, it negates its value. The unary minus operator represents the prefix-sign in C++. You must put the-sign before a number to negate it; for example, if you want to negate 5, you will type ...
