In this article, we are going to learn what are the different ways to pass parameters to function in c++ We can pass parameters to a function in three ways. Pass by value Pass by reference Pass by pointer Pass by value: In this method, the copies of values of actual parameters are passed to …
INTRODUCTION In this tutorial, we are going to learn about functions and types of functions in C++. Firstly, we will learn what is a function. A function is a group of statements that together performs a specific task. Every programming language has at least one function, that is main(). you can break the entire code into …
We can still use all the functions present in C Language <string.h> library as including <cstring> and make use of all its string handling functions. The string is an object of std::string class in c++. It provides many of the in-built functions that can be used with the strings without including any library. These are …
Introduction: In this article, we are going to learn about the string data type in C++ libraries. the C++ programming language has support for string handling, implemented in its standard library. String: A string is a variable that stores a sequence of letters or other characters. A string variable is surrounded by double quotes. String …
INVALID POINTERS A pointer is said to be an invalid pointer: 1. If it is not initialized 2. When a pointer points to a valid address but not valid elements(in arrays) Let’s look at some examples of invalid pointers. In the above examples, ptr1 is declared but not initialized. Ptr2 is assigned to arr+20, but …
In this article, we are going to learn types of pointers Advanced Pointer Notations: There are some other ways where pointers get in handy. Pointers with multidimensional arrays: Pointers can also be used with multidimensional arrays. For example, look at the below multi-dimensional array sample. Consider pointer notation for the two-dimensional numeric arrays. consider the …
In this article, we are going to learn about the pointers in c++. Pointers are the variables used to store the address of another variable. They are the symbolic representation of the addresses of the variables. However, pointers are considered to be one of the toughest topics to learn in c++. It has many advantages …
In this article, we are going to learn about the types of arrays present in cpp. In C++, there are generally three types of arrays present. They are One-dimensional array Two-dimensional array Multidimensional array ONE-DIMENSIONAL ARRAY A one-dimensional array in C++ is used to store the elements of the same data type in one dimension. …
In this tutorial, we will learn about arrays and different types of arrays in C++. INTRODUCTION: Firstly, what is an array?An array is a collection of a group of similar data items which can be referred to as a single element. Array elements are stored at contiguous memory allocation and array elements can be randomly …
In this tutorial, we will learn about the applications of loops. Introduction: In this article, we will implement the loops concept that we have learned in the previous article. For example, let’s say we want to show a message 100 times. Then instead of writing the print statement 100 times, we can use a loop.That …
