Answer:
Border Gateway Protocol is a protocol the routers use to determine the most optimal path to forward the traffic.
Explanation:
BGP is a path vector protocol which chooses the most optimal path. The protocol decides core routing decisions based on path, configuration and network.
This protocol gives all the notification about the status of the connection and router.
It is used to routing in an autonomous system and provides ways to measure the effectiveness of configuration.

}
setPublisher(String ) {
this. =;
}
public int get() {

}
set(int ) {
this. = ;
}
The issue arises because the string you are trying to print is not a string, rather a float value. Item1, item2 and item3 are strong values (if you type some alphabets in it and not just numbers), but itemonecost, itemtwocost, and itemthreecost are explicitly type casted to float. In line 22, 23, and 24 you’re trying to print a float, by adding it with the string. One cannot add numbers to string. Rather you can type cast the itemcost to string while printing.
Add str(itemonecost) instead of itemonecost in print statement. Do this for other float variables too.
However do note that there are multiple ways to correct this issue, and I’ve just pointed one out.
