How to use append() function In C++
Create a string and append characters one by one into that string by traversing into the container.
Syntax:
string_name.append(1, character);
Example:
C++
// C++ program to convert vector of chars // into string Using append() function #include <bits/stdc++.h> using namespace std; int main() { vector<char> v = { 'A', 'B', 'C', 'D', 'E' }; string s; for (char& c : v) { s.append(1, c); s.append(1, ' '); } cout << s; return 0; } |
Output
A B C D E
