How to resolve incompatibility between actual and formal parameters in C language?

In C language, the incompatibility between actual parameters and formal parameters usually refers to their data types not matching. To address this issue, several methods can be adopted:

Type conversion: This involves converting the actual parameter to the data type required by the formal parameter. This ensures data type compatibility but should be used cautiously to prevent data loss or unexpected results.

2. Edit function parameters: If possible, adjust the function’s parameters to match the data type of the arguments.

3. Modify the calling code: When calling a function, make sure that the data types of the actual arguments match the formal parameters. You can modify the calling code, or perform type conversion before the call.

4. Using pointers or references: By passing pointers or references as parameters, you can avoid the issue of mismatching data types. This allows you to directly manipulate the values of actual arguments without needing to copy data.

In conclusion, to address the issue of incompatible actual and formal parameters, it is necessary to consider aspects such as data type matching, type conversion, and parameter passing, and choose the appropriate method for processing.
