name.charAt(0);
Explanation:
Given: 'name' is a variable of type String that has been assigned a value.
To determine: an expression whose value is the first character of the value of name.
Let us assume nae is assigned the value "test". So our expression should return the first character , that is 't'.
In order to do this, we can use the charAt method of String object.
String name="test";

A backdoor is a typically covert method of bypassing normal authentication or encryption in a computer, product, embedded device, or its embodiment. Backdoors are most often used for securing remote access to a computer, or obtaining access to plaintext in cryptographic systems.
Explanation:
Here is code in Python.
#integer value 3 assigned to variable a.
a=3
#integer value 4 assigned to variable v.
b=4
# the value of given expression a * a b *b will be assign to variable c .
c=(a*a)*(b*b)
Explanation:
First an integer value is assigned to variable "a".And then integer 4 is assigned to variable "b". Calculate the value of expression a*ab*b and assigned to variable "c". Here expression a*ab*b can also be written as (a*a)*(b*b).
