please help me with these functions for study C++

The PARAMETER: An int or more storing values.

1. Delete the last node of the calling object.
2. Delete the node before-last of the calling object.
3. Replace the value of the first node of the calling object with the value passed by the parameter.
4. Replace the value of the last node of the calling object with the value passed by the parameter.
5. Replace the value of the second node of the calling object with the value passed by the parameter.
6. Replace the value of the second-to-last node of the calling object with the value passed by the parameter.
7. Given two int parameters, oldValue and newValue, replace the first occurrence of the oldValue with the newValue.
8. Given two int parameters, oldValue and newValue, replace all occurrences of the oldValue with the newValue.
9. Traverse the calling object and search for the value passed by the parameter; return true if found and false if not found. Make sure you stop the loop if the value is found; no need to keep on iterating.

Thank you for your help
