A team from IBM developed the DES (Data Encryption Standard) algorithm, a symmetric-key block cipher that was later accepted by the National Institute of Standards and Technology (NIST).
How DES implemented?Using 48-bit keys, the technique transforms ordinary text, which is presented in 64-bit blocks, into ciphertext.
An antiquated symmetric key technique for data encryption is the Data Encryption Standard (DES). The standard was created by IBM researchers in the early 1970s.
Therefore, for the purpose of protecting sensitive material, it was adopted by government organizations in 1977 and formally retired in 2005.

consider the following method definition in a class: public double multiply(double a, double b) which of the following is not a legitimate case of overloading this method?
The function secret in it only accepts the first integer and second double inputs, even though you pass all integer variables.
The set Vehicle Class function is overloaded by the Auto class in this line of code. This is so that, in the event that a super-class and a sub-class both have a method, the sub-class either overrides or overloads the super-class method. Because the arguments are different in this instance, the sub-class Auto is overloading the set Vehicle Class function. The parameters for the Auto class methods are of type int, whereas those for the super-class methods are of type double. Therefore, if an int is supplied as an argument, the method will overload.

There are four mistakes. public key phrase. In C, string is not a datatype. That'd be char. This.id and this.name both have undeclared identifiers.
The following program's output is 56. The code sample shown initializes x with 5 and y with 0. Since x++ is a post increment operator, the statement y=x++ will then assign the value 5 to y and increase the value of x. As a result, after this sentence, x will increase in value. The first print command will output the value of y, which is 5, and the second print command will output the value of x, which is 6, both without spaces. Therefore, 56 will be the output. Because we are using the post fix increment operator and increasing 33 to 34 when we call move Point(p,1,1), 33 is there because the value will be decreased later.
