Differentiate single dimensional array to double dimensional array?
A single dimensional array is an array of items. A two-dimensional array is an array of arrays of items.
How do you achieve multiple inheritance?
Any class can extend one class and/or implement multiple interfaces. For example: public class TestClass extends SuperTestClass implements InterfaceA, InterfaceB { // implementations of interface methods in here }
What are the difference between DES and RSA algorithm?
DES is a symmetric cryptographic algorithm, while RSA is an asymmetric (or public key) cryptographic algorithm. Encryption and decryption is done with a single key in DES, while you use separate keys (public and private keys) in RSA. DES uses 56-bit keys for encryption while RSA uses 2600-bits of KEY
What is Array in Programming C?
Arrays allow similar types of data to be stored within a contiguous block of memory such that every data element is accessible in constant time, regardless of its physical location within the array. This is achieved through simple pointer arithmetic treating each element as a memory offset from the start of the array. Since every element is the same length (in bytes), locating any element is simply a matter of calculating its offset from its index. Indices are zero-based thus the third element can be found at index 2. The memory offset for that element is therefore the product of the element size and 2. However, C permits indices to be specified directly, while the pointer arithmetic is done in the background. Thus array_name[2] automatically returns a reference to the third element. Arrays with large and complex variable length data elements need to store those elements separately from the array, usually non-contiguously. This is achieved by using a pointer array. Pointer arrays are particularly useful when sorting extremely large data lists as it is much easier and more efficient to implement a sorting algorithm with an array than it is with a linked list, particularly when constant-time random-access is essential to the algorithm. The time and effort in building the array is generally more than compensated for by the efficiency of the algorithm. Arrays can also be divided and subdivided to better model the data they represent. For instance, a chessboard might be implemented as a one-dimensional array of 64 elements, however it makes more sense to model the chessboard in a two-dimensional array of 8x8 elements. Although the array is still allocated contiguously and can be thought of as being 8 rows and 8 columns, it's actually better to think of this two-dimensional array as being a one-dimensional array of 8 elements, where each element is another one-dimensional array of 8 elements. By thinking this way it makes it possible to allocate extremely large arrays in non-contiguous memory (as completely separate one-dimensional arrays) and also makes comprehension of a four-dimensional array in a three-dimensional world that much easier (unless you actually want to model time and space of course). A four-dimensional array can be thought of in a variety of ways: as being a one dimensional array of three-dimensional arrays, or as a two-dimensional array of two-dimensional arrays, or as a three-dimensional array of one-dimensional arrays, or even as a one-dimensional array of one-dimensional arrays of one-dimensional arrays of one-dimensional arrays. Whichever method you use to imagine your array is immaterial, so long as it makes sense to you that's all that really matters.
What is the difference between programming and algorithm?
A program is a detailed set of instructions for a computer to carry out, whle an algorithm is a detailed sequence of steps for carrying out a process.

Need of interface in java?
Interfaces are used in Java to accomplish most of the goals of Multiple Inheritance. For several reasons, Java only supports Single Inheritance for classes - i.e. a class can have only a single parent. The use of Interfaces is how Java attempts to implement most of the positives of the concept of Multiple Inheritance while avoiding its pitfalls.
Which of the following are true. 1.single gene can control a single trait 2.single gene can influence multiple traits 3.single trait can be controlled by multiple genes?

How Mandy cubes does it take to make a 3 dimensional figure?

What graph shows how output changes when a single input changes?
A multi-dimensional scatter plot.A multi-dimensional scatter plot.A multi-dimensional scatter plot.A multi-dimensional scatter plot.
How do you implimenting multilevel inheritance in java?
In java we can implement more than one interfaces for a single class but we can't extend a class to more than one super class so ,java indirectly supports multiple inheritance.
