Convert Vector of Characters to String in C++ Last Updated : 03 Dec, 2024 Comments Improve Suggest changes Like Article Like Report In this article, we will learn different methods to convert the vector of character to string in C++.The most efficient method to convert the vector of characters to string is by using string's range constructor. Let’s take a look at an example: C++ #include <bits/stdc++.h> using namespace std; int main() { vector<char> v = {'a', 'b', 'c', 'd', 'e'}; // Convert vector of char to string string s(v.begin(), v.end()); cout << s; return 0; } OutputabcdeExplanation: In the above code, we directly initialized the string s with the characters of the vector using its range constructor.There are also some other methods in C++ by which we can convert the vector of character into string. Some of them are as follows:Table of ContentUsing accumulate()Using StringstreamUsing push_back()Using accumulate()The accumulate() method can also be used to convert the vector of character to string by iterating through every character and append it to resulting string. C++ #include <bits/stdc++.h> using namespace std; int main() { vector<char> v = {'a', 'b', 'c', 'd', 'e'}; // Convert vector of character to string string s = accumulate(v.begin(), v.end(), string(), [](const string &a, char b) { return a + b; }); cout << s; return 0; } OutputabcdeUsing StringstreamCreate a stringstream and insert all characters from the vector into it. After all characters are added, the stringstream str() function is called to convert the contents of the stream into a single string. C++ #include <bits/stdc++.h> using namespace std; int main() { vector<char> v = {'a', 'b', 'c', 'd', 'e'}; // creating stringstream object stringstream ss; // Insert every character of vector into stream for (auto it = v.begin(); it != v.end(); it++) ss << *it; // converts stream contents into a string cout << ss.str() << endl; return 0; } Outputabcde Using push_back()Iterate through the vector and add every character of vector into resultant string one by one using string push_back(). C++ #include <bits/stdc++.h> using namespace std; int main() { vector<char> v = {'a', 'b', 'c', 'd', 'e'}; string s; // Convert vector of character to string for (auto i : v) s.push_back(i); cout << s; return 0; } OutputabcdeIn this method, we can replace the string push_back() method with string append() or even string insert() method.

The std::string in c++ has a lot of inbuilt functions which makes implementation much easier than handling a character array. Hence, it would often be easier to work if we convert a character array to string. Examples: Input: ch 4 min read How to Convert a Single Character to String in C++? A string is a generally made up of a sequence of multiple characters. In this article, we will learn how to convert a single character to a string in C++.Example:Input: c = 'A'Output: s = "a"Explanation: Character c is converted to a string.Input: c = '#'Output: s = "#"Explanation: Character c is co 4 min read Convert char* to std::string in C++ Strings are generally represented as an instance of std::string class in C++. But the language also supports the older C-Style representation where they are represented as array of characters (char* or char[]) terminated by null character '\0'. In this article, we will learn how to convert the char* 3 min read How to Convert a std::string to char* in C++? In C++, strings are the textual data that is represented in two ways: std::string which is an object, and char* is a pointer to a character. In this article, we will learn how to convert a std::string to char* in C++. Example Input:string myString = "GeeksforGeeks";Output:char * myString = "Geeksfor 1 min read Convert String to Integer Vector in C++ Strings are sometimes used to represent the numerical data which needs to be converted back to integer, but sometimes we may need to convert it to vector of integers instead due to some problems such as too large integer. In this article, we will learn different way to convert a string to integer ve 2 min read Convert String to Char Array in C++ In C++, we usually represent text data using the std::string object. But in some cases, we may need to convert a std::string to a character array, the traditional C-style strings. In this article, we will learn how to convert the string to char array in C++.ExamplesInput: str = "geeksforgeeks"Output 4 min read How to Convert Hex String to Byte Array in C++? A Hex String is a combination of the digits 0-9 and characters A-F and a byte array is an array used to store byte data types only. The default value of each element of the byte array is 0. In this article, we will learn how to convert a hex string to a byte array. Example: Input: Hex String : "2f4a 2 min read C++ Program to Sort String of Characters Sorting a string means rearranging the characters of the given string in some defined order such as alphabetical order. In this article, we will learn how to sort a string by characters in C++.ExamplesInput: str = "geeksforgeeks"Output: "eeeefggkkorss"Explanation: The characters in the string are so 4 min read How to Convert std::string to Lower Case? Converting string to lower case means all the alphabets present in the string should be in lower case. In this article, we will learn how to convert the std::string to lowercase in C++.Examples Input: s = "GEEKS for GEEKS"Output: geeks for geeksExplanation: All characters of s are converted to lower 3 min read C Program to Extract Characters From a String Character extraction can be done by iterating through the string in the form of a character array. It basically means plucking out a certain amount of characters from an array or a string. Now, to take input in C we do it by using the following methods: scanf("%c",&str[i]); - Using a loopscanf(" 2 min read Like
