Memory leakage and Memory leakage

Memory leakage and Memory leakage
Analyze prompt: Value stored to "xxx" is never read

Analysis: The current variable is not used. Search for the variable in the current class and find that the variable is only assigned and not used.

Solution: Remove this prompt: delete or watch this line of code OK;

Analyze prompt: the left operand of ** is a garbage value

Analysis: When the variable on the Left does not meet the above if condition, the variable on the left is not assigned a value for =, which causes such a warning.

Solution: You can initialize a value for the variable = on the left, or make sure there is a value for the if judgment.

 

 

I will continue to make up for other cases. Please help me with the help. Thank you.
