Question

What is Strings in C++ with example?

Answer 1

Strings in C++ are sequences of characters that can be manipulated using various functions. A string is created using the string class, which allows for dynamic changes in length and provides multiple operations like concatenation, comparison, and searching.

Step-by-step explanation:

Understanding Strings in C++

In C++, strings are sequences of characters used to store text. A string can be created using the string class provided by the C++ Standard Library, which offers a variety of functions to manipulate strings. Here's a simple example:

#include
#include

int main() {
// Creating a string using the string class
std::string greeting = "Hello, World!";

// Output the string
std::cout << greeting << std::endl;

return 0;
}

This program defines a string variable named greeting, assigns it the value of "Hello, World!", and then outputs it to the console. In C++, strings are dynamic and can change in length, which gives them flexibility over character arrays. When working with strings in C++, you can perform operations like concatenation, comparison, and searching, among others.

Answer 2

A string is a variable that stores a sequence of letters or other characters, such as "Hello" or "May 10th is my birthday!". Just like the other data types, to create a string we first declare it, then we can store a value in it


example program:
#include #include using namespace std;
#include "console.h"
int main() { string test;
test = "I am Q the omnipot3nt";
char ch = test[5]; // ch is 'Q'
test[18] = 'e'; // we correct misspelling of omnipotent
cout << test << endl;
cout << "ch = " << ch << endl; return 0
