This article provides a comprehensive overview of arrays and strings in C++ programming language along with example programs. Arrays Introduction An array is a group of elements forming a complete unit. Characteristics of an array are as follows: An array is a collection of elements. All elements in an array are of the same […]
This article provides a comprehensive overview of C++ basic concepts along with easy to understand examples. Tokens Smallest indivisible parts of a program are called lexemes and groups of similar lexemes are called tokens. C++ program contains several items and those are identified as tokens by a compiler. C++ tokens are as follows: Keywords […]
This article provides a comprehensive overview of input and output in C++ programming language along with example programs. Any program in a given programming language needs significant amount of input from the user and also needs to display to the output several times. To support such I/O operations, C++ provides a library which contains […]
In this article we will look at introduction to C++. First we start with the history of C++ and move on to the basic structure of a C++ program. History of C++ C++ was developed by Bjarne Stroustrup in 1979 at AT&T Bell Labs. C++ is an object-oriented language which includes imperative as well […]
This article provides a comprehensive introduction to object oriented paradigm along with real-world examples. This world is made up off several objects and objects communicate with each other. Similar objects can be grouped together. For example, take a college. It can have two working sections like teaching and non-teaching. These two groups can be […]

A C program is provided below to read and print a matrix using pointers and dynamic memory allocation. Program is as follows: #include<stdio.h> #include<stdlib.h> int main() { int m, n; printf("Enter no. of rows and […]
In this article we will learn to implement a C program to find the unique element in an array. A C program is provided below to print the unique element in the given array. Note: This program works only when the values are repeated two times and when there is only one unique value. […]
In this article we will learn to implement a C program to reverse a given string. A C program is provided below to reverse a given string without using predefined function. Program is as follows: #include<stdio.h> #include<string.h> int main() { char str[20]; printf("Enter a string: "); scanf("%s", str); int length = strlen(str); for(int i=0, […]
