what is unity ???

Image
unity is a across-platform game engine developed by unity technologies, first announced and released in june 2005 at apple inc. worldwild developers conference as an os x-exclusive game engine. As of 2018, the engine has been extended to support 27 platforms.the engine can be used to create both 3D and 2D games as well as simulation for desktop and laptops, home consoles, smart TV, and mobile devices several major versions of unity have been released since its launch, with the latest stable version being unity 2018.2.2, released on august 10, 2018.

java script data type.

One of the most fundamental characteristics of a programming language is the set of data types it supports. These are the type of values that can be represented and manipulated in a programming language. JavaScript allows you to work with three primitive data types:  Numbers, e.g., 123, 120.50 etc  Strings of text, e.g. "This text string" etc.  Boolean, e.g. true or false. JavaScript also defines two trivial data types, null and undefined, each of which defines only a single value. In addition to these primitive data types, JavaScript supports a composite data type known as object. We will cover objects in detail in a separate chapter.  Note: Java does not make a distinction between integer values and floating-point values. All numbers in JavaScript are represented as floating-point values.

Write a C++ program that outputs the following text on screen:

text-oh what a happy day ! oh yes, solution / / Let's go  ! #include  <iostream> uning namespace std; int main ( ) {      count  << "  oh what " << endl ;      count  << "  a happy day! " << endl;      count  << "  oh yes, " << endl;      count  << "  what a happy day! " << endl;            return  o ; }

String operations in C language.

We have already mentioned the mentioned the string functions strlen, strcpy, strcat, and strcmp, found in <string.h>. In the following, s and t are char *s, and c and n are intact.

Whai is block structure???

C is not a block structure language in Tha sense of Pascal or similar language, because function may not be defined within other function. On the other hand, declarations of variables (including initializations) may follow the left brace that introduce any compound statement, not just the one that begins a function. Variable declared in this way hide any identically named variables in outer blocks, and remain in existence until the matching right brace. For example​, in If (n > o) { Int i; /* declare a new i */ For (i = o ; i < n ; i++) . . . }

How can we copying file in C language.

Given getchar and putchar, you can write a surprising amount of useful code without knowing anything more about input and output. The simplest example is a program that copies it's input to it's output one character at a time
