Call using delegated InferenceCodeAs follows:
Int P2 = getpowersum (squaresum );Int P3 = getpowersum (cubesum );
The code for creating a delegate object is as follows:

Modify the default prompt (the default value is "#? "):
PS3 = "select a project :"
You are prompted to select a value from the array:
Select project in $ {projects [*]}; do if [$ project]; then break fi done
Or add the Exit condition: select target_ip in $ {servers [*]} "Exit (Exit)"; do if ["$ target_ip" = "Exit (Exit)"]; then echo "Thank you! Good-Bye! "Break fi
If [$ target_ip]; then # do something fi done

Ii. Proxy server bandwidth
Another bottleneck of campus network bandwidth is the bandwidth connected to the Internet. Most of the domestic leased line access bandwidth is only 64 ~ Between 256 kb and kb, most of them use proxy servers to speed up Intranet access. For internal network security, proxy servers all have firewall functions, but the current firewall has great defects.
