In this article, we will create a Snake game using C++ and graphic functions. We will implement it using the concept of C++ classes and computer graphic functions. What is the Snake Game? The Snake game is a very famous game that can be played on various devices and runs on any operating system. In … Read more
C++ comments are statements that are not executed by the compiler. Comments in C++ programming can be used to explain code, variables, methods, or classes. With comments, you can also hide program code. There are two types of comments in C++: Single-line comments Multi-line comments 👇Click to receive👇 👉C Language Knowledge Resource Collection C++ Single-line … Read more
printf() and scanf() functions are used for input and output operations in C language. These two functions are built-in library functions defined in stdio.h (header file). printf() Function printf() function is used for output operations. It prints the given statement to the console. The syntax of the printf() function is as follows: printf("format string", argument_list); … Read more
Standard header files include: <asset.h> <ctype.h> <errno.h> <float.h> <limits.h> <locale.h> <math.h> <setjmp.h> <signal.h> <stdarg.h> <stddef.h> <stdlib.h><stdio.h> <string.h> <time.h> 1. Standard Definitions (<stddef.h>) The file <stddef.h> contains some common definitions of the standard library, and it is automatically included whenever any standard header file is included. This file defines: Type size_t (the result type of the … Read more
Source: Content from the internet, thank you! C++ Comments Comments in a program are explanatory statements, and you can include comments in C++ code to enhance the readability of the source code. All programming languages allow some form of comments. C++ supports single-line comments and multi-line comments. All characters in a comment will be ignored … Read more
C++ programs can be defined as a collection of objects that interact with each other by calling their methods. Objects Objects have states and behaviors. For example: a dog’s state – color, name, breed; behavior – wagging, barking, eating. Objects are instances of classes. Classes Classes can be defined as templates/blueprints that describe the behaviors/states … Read more
In C++, strings are objects of the std::string class, representing sequences of characters. We can perform many operations on strings, such as concatenation, comparison, conversion, etc. C++ String Example Let’s look at a simple example of a C++ string. #include <iostream>using namespace std; int main() { string s1 = "Hello"; char ch[] = { 'C', … Read more
C++ expressions consist of operators, constants, and variables arranged according to the rules of the language. They can also include function calls that return values. An expression can consist of one or more operands and zero or more operators to compute a value. Each expression produces a value that is assigned to a variable via … Read more
So far, we have learned about the two types of variables supported by C++: Ordinary variables are variables that hold values of a certain type. For example, creating an integer variable means that the variable can hold integer values. Pointers are variables that store the address of another variable. You can retrieve the value pointed … Read more
As we know, pointers are used to point to variables; similarly, function pointers are used to point to functions. They are primarily used to store the address of a function. We can use function pointers to call functions or pass function pointers as parameters to another function. Function pointers are mainly useful in scenarios such … Read more
