What should main() return in C and C++?
In C/C++, the main() function is used in the beginning of every program. This returns the program execution status in the operating system. Syntax Following is the syntax of the main() function using C/C++: int main(void); int main(int argc, char *argv[]); Example Below, the C/C++ example shows the usage of the main() return value. C C++ #include int main() { printf("Hello, C World!"); return 0; } Key Points of C Return 0: This is standard for successful execution Non-zero: It indicates error Implicit return: C99 allows omitting return #include int main() { std::cout
Read MoreConvert a C++ String to Upper Case
In C++, converting a string into uppercase means changing all the characters into uppercase. This is a common requirement in many applications, such as formatting output, standard data input, and case sensitivity. Following is the table that shows the conversion of string to uppercase: String Case Characters Uppercase Characters ...
Read MoreC++ Program to Convert Octal Number to Binary Number
In a computer system, the binary number is expressed in the binary numeral system while the octal number is in the octal numeral system. The binary number is in base 2 while the octal number is in base 8. Here, we provide the tabular data to understand binary numbers and their corresponding octal numbers as follows: Octal Number ...
Read MoreC++ Program to Implement Parallel Array
A parallel array is a structure that contains multiple arrays. Each of these arrays are of the same size and the array elements are related to each other. All the elements in a parallel array represent a common entity. Here, we provide the basic example to understand the parallel array in C++ − employee_name = { Harry, Sally, Mark, Frank, Judy } employee_salary = {10000, 5000, 20000, 12000, 5000} Here, The name and salary of 5 different employees is stored in two different arrays. Example of Parallel Arrays This is an implementation of a parallel array ...
Read MoreDifferent Types of Database Users
Database users interact with data to update, read, and modify the given information daily. There are various types of database users and we will learn in detail about them. Database users can be divided into the following types − Naive users / Parametric users Sophisticated users End Users Application Programmer or Specialized users or Back-End Developer System Analyst Database Administrator (DBA) Temporary Users or Casual Users These users can access the database and recover the data using various applications. Let’s have a quick understanding of all the types in detail − End Users/Parametric Users These users access the ...
Read MoreJava program to check whether the number is divisible by 5
In mathematics, the divisibility rule of 5 states that if the number ends with 0 or 5 then it will divisible by 5. There is another way to identify the divisibility rule of 5, if the remainder comes to 0 it returns the number is divisible by 5. The mod(%) operator is normally used in programming when it comes to divisibility. Following are some examples which helps you to understand the divibility rule of 5 − Given number is 525, the number ends with 5 and it is divisible by 5. Given number is 7050, the number ends with ...
Read MoreCheck whether all the substrings have number of vowels atleast as that of consonants
In Alphabetical series there are consists of 26 characters of which 5 characters are vowels such as a, e, i, o, u and the rest are called as consonants. In C++, we have predefined functions such as tolower() and length() that will help to Check whether all the substrings have number of vowels atleast as that of consonants. Let’s take an example of this. The string has only one consonant with the rest vowel “aiteau”. Hence, it is accepted as the final result. The string has more than one consonant with the rest vowel “appioa”. Hence, it is not ...
Read MoreMaximum distance between two points in coordinate plane using Rotating Caliper’s Method
In C++ we have a predefined function sqrt that returns the square root of any number. The Rotating Caliper’s Method is the technique used to solve the algorithmic or computational geometry. Visual Representation of Rotating Caliper’s MethodThe hand rotation shows the real example of a rotating caliper graph, whenever the hand rotates the perpendicular direction is shown. We can also understand this concept by using a polygon shape. In this article, we are going to find the maximum distance of two coordinate points using Rotating Caliper’s Method. Syntax The following syntax used in the program − vector name ...
Read MoreHow to Draw Dynamic Animation in HTML5?
HTML has division and button elements that can be used to draw Dynamic Animation. The ability to generate interactive and visually graphics using web technologies is referred to as dynamic animation in HTML5. HTML5 includes a number of complex tools that enable developers to build dynamic and responsive animations by combining HTML, CSS, and JavaScript. Animations extend from simple state transitions through complex interactive models and games. One of the primary advantages of implementing HTML5 for animation is that it is platform-independent and can run on a wide range of platforms, including desktop and mobile devices. HTML5 thus provides a strong tool ...
Read MoreHow to draw with mouse in HTML 5 canvas?
HTML5 has a division element to create the box to draw with the mouse. Developers can create dynamic, interactive graphics for the web using the strong and adaptable HTML5 canvas technology. Drawing on canvas can be performed with a variety of tools and methods. The users can create free-form shapes and lines by dragging their cursor across the canvas when drawing with a mouse, i.e. a common technique. Simple sketches of all diagrams and illustrations will be produced using this method. Properties Used The following properties are used in the example − width − Define the width of the ...
