Code read elements in an array from user and count total number of duplicate elements in array. C program code to find all duplicate elements in an unsorted array. How to list all

String is a "sequence of characters". char data type is used to represent one single character in C++. So if you want to use a String in your program then you can use an "array of chars".

Takes input a Character and Check it whether a 'character' is capital letter, small letter, Digit or Special character. 'All characters' like small or capital letters, digits and special characters

The Fibonacci sequence is a series where the next term is the "sum of pervious two terms". The first two terms of the Fibonacci sequence is 0 followed by 1. Fibonacci Numbers: 0, 1, 1,

Combined two strings means add both string with each other, perform this operation using 'library function' or without library function. If first string is 'john' and second string is porter

A 'positive integer' which is only divisible by 1 and itself is known as prime number. So 13 is a prime number because it is only divisible by 1 and 13 but, 15 is not prime number because
