In the above code, what happens to the value of aNumber when the main() method is executed? What happens to the value of aNumber when the firstMethod and secondMethod methods are executed?
What will be an ideal response?
Initially, aNumber is declared and assigned the value 10 in the main() method of the OverridingVariable class. When the program calls firstMethod(), a new variable is declared with the same name. However, a different memory address is used and a new value is assigned. The new variable exists only within firstMethod(), where it contains the value 77. After firstMethod() executes and the logic returns to the main() method, the original aNumber is displayed with a value of 10. A copy is made within the method when aNumber is passed to secondMethod(). This copy has the same identifier as the original aNumber, but a different memory address. When the value is changed to 862 and displayed within the secondMethod(), it has no effect on the original variable in main(). When the logic returns to main() after secondMethod(), the original value is displayed again.

Log Files and Syslog
Because of their importance, it is common practice to concentrate log files in one monitoring computer. Syslog is a system designed to allow devices to send their log files to a centralized server, known as a syslog server. Clients communicate to a syslog server using the syslog protocol. Syslog is commonly deployed and supports practically all computer platforms. The CyberOps Workstation VM generates operating system level log files and hands them over to syslog.

What is wrong with the following function?void* _retrieve (AVL_TREE* tree, void* keyPtr, NODE* root){ if (tree->compare(keyPtr, root->dataPtr) < 0) return _retrieve(tree, keyPtr, root->left); else if (tree->compare(keyPtr, root->dataPtr) > 0) return _retrieve(tree, keyPtr, root->right); else return root->dataPtr; } // if root}
A. It is missing one recursive call to _retrieve. B. The first if should be "if (tree->compare(keyPtr, root->dataPtr) < 0)". C. The second if should be "if (tree->compare(keyPtr, root->dataPtr) >= 0)". D. It does not check if the data is not in the tree.
