Print first and last character of each word in a string
Introduction A C++ string is contiguous storage of alphanumeric characters as well as special characters. A string has the following properties − Every C++ string is associated with a fixed length. Character operations can be easily performed with the string characters. A string is composed of words, which are space separated. In this article, we are going to develop a code that takes as input a string, and displays the last character of each word in the string. Let us look at the following example to understand the topic better − Sample Example Example 1 − str − ...
Read MorePrint last character of each word in a string
Introduction C++ strings are essentially a combination of words used as a storage unit to contain alphanumeric data. The words in a string are associated with the following properties − The word positions begin with 0. Every word is associated with a different length. The characters combine together to form words, which eventually form sentences. By default, the words are separated by a space character. Every word contains at least one character. In this article, we are going to develop a code that takes as input a string, and displays the last character of each word in ...
Read MorePairs of strings which on concatenating contains each character of “string”
Introduction A stream of characters flowing together collectively comprising of alphanumeric characters as well as special symbols can be termed as a C++ string. String concatenation is an important aspect of the string data structure, since it is used to combine different sub strings or words to form complete sentences. Concatenation in C++ can be simply done using the + operator. In this article, we are going to develop a code that takes as input an array of string, and then analyses each pair to see if that pair contains all the letters of the word “string” . Let us ...
Read MoreEncrypt a string by repeating i-th character i times
Introduction A C++ string is a fixed sequence of alphanumeric characters. It is a continuous stream of occurring characters, which may be digits, characters or even special symbols. Every string is characterized by a definite length. The positions by which the characters are accessed begin with 0. Strings can contain unique or repeated characters concatenated together. They can be subjected to various manipulations and concatenation operations. In this article, we are going to develop a code that takes as input a string, and displays the encrypted string, wherein the first character is repeated 1 time, the second character is ...
Read MoreCount of strings satisfying the given conditions
Introduction A string in C++ is also a primitive data type which is comprised of alphanumeric characters. The letters in a string are case sensitive, but strings can contain both upper and lower case. In this article, we are given an input array of lowercase strings, and require the count of the pair of strings from the array satisfying the following conditions − Both the strings should have the same first and last vowel Both the strings have an equal number of pairs An array is a data structure simulating the storage of similar elements. A C++ array ...
Read MoreCount of pairs of strings which differ in exactly one position
Introduction A string is composed of alphanumeric characters, each of which is associated with a definite position. The positions of the characters range from 0 to the string length. The characters differing exactly in one position are said to be adjacent. In this article, we are going to develop a code that takes as input an array of strings which differ in exactly in one position. Let us look at the following example to understand the topic better − Sample Example Example 1 − str − {“abc”, “cba”, “dbc” , “acc”} Output − 2 For instance, in ...
Read MoreCount of buttons pressed in a keypad mobile
Introduction A string in C++ is an in-built storage structure used to contain digits, characters or even special symbols. Every string is associated with a definite size, specified by its length attribute. By default, the string positions begin with 0. The characters in string can be subjected to various types of manipulations − New characters can be appended at the end of a string. A character can be appended multiple times to the string. In this article, we are going to develop a code that takes as input a string, and counts the number of times the keys ...
Read MoreCheck if the string contains consecutive letters and each letter occurs exactly once
Introduction A string in C++ is a sequence of characters, which may be distinct or repetitive in nature. Consecutive characters are the characters occurring simultaneously, with a difference of 1. For instance, the characters a and b are consecutive, since they occur together. However, the characters m and o have a difference of 2 in their positions, which make them non-consecutive in nature. In this article, we are going to develop a code that takes as input a string, and displays true in case all the characters in a string are consecutive. Let us look at the following example ...
Read MoreCharacter whose frequency is equal to the sum of frequencies of other characters of the given string
Introduction A C++ string is a stream of alphanumeric characters. A string has the following properties − A string is composed of a fixed set of characters The strings positions start by default from the 0th index Frequency of any character is the number of times it occurs in the string. The frequency of any any character can range from 0 , if it doesn’t occur to the length of the string. In this article, we are going to develop a code that takes as input a string, and checks whether the frequency of any character is equivalent ...
Read MoreSentence Case of a given Camel cased String
A C++ string is a collection of characters forming words. It may contains letters, numbers and even special characters. The sentences of a string can be clubbed together in different ways to form different types of representations. The camel case of a string denotes the string in such a way that the following two properties are maintained − The words are joined together, there is no space character. Every word has the first letter stored in upper case. Thereby, the upper case letters in this form of representation can be used to segregate the different words. This type ...
