Imagine you are programming a simple command interpreter for a robotic exploration system. The robot can accept textual commands to navigate an environment, perform tasks, or enter standby mode. For safety and control, the system must recognize a specific command, "halt", to immediately cease all operations and enter a safe mode.

Given a C$-$string variable command that holds the current command issued to the robot, write an expression that evaluates to true if command equals the C$-$string "halt". Assume command is a null$-$terminated character array, and use appropriate C$++$ string handling functions to perform the comparison.
