Summary: In this programming tutorial, we will learn different ways to convert a string into a char array in C++. Method 1: Using ‘for loop’ #include <iostream> using namespace std; int main() { string str; c
Compile: g++ stringtest.cpp -o stringtest Run: ./stringtest Results for both examples: This is a string This is a string The C and C++ methods of managing a character data type are both valid but we will see that the C++ string class offers more functionality and convenience. The...
C++ has several methods to modify strings. modify.cpp #include <iostream> using std::string; using std::cout; using std::endl; int main() { string msg = "an old"; msg.append(" falcon"); cout << msg << endl; msg.push_back('.'); cout << msg << endl; msg.pop_back(); ...
These methods are explained clearly in the following parts of this chapter −Using strlen() Method Using string::length() Method of String Class Using string::size() Method of String Class Using Iterative for Loop Using Iterative while Loop ...

While the Regex type methods can be used to Split strings effectively, the string type Split method is faster in many cases. The Regex Split method is static; the string Split method is instance-based. The next example shows how you can specify an array as the first parameter to string Sp...
Usingstd::stringwithstd::cinmay yield some surprises! Consider the following example: #include<iostream>#include<string>intmain(){std::cout<<"Enter your full name: ";std::string name{};std::cin>>name;// this won't work as expected since std::cin breaks on whitespacestd::cout<<"Enter...
Using String Keyword:We can also use the string keyword of C++ to declare and define string arrays. Using STL Vectors:We can use STL vectors wherein each element of a vector is a string. Now, let’s discuss each of the above methods and also see the programming examples for each represe...
Another option to avoid the bloat issue in certain cases is to use enums as an alternative to variables or you could also usegettermethods to return the constant values, such as // myapi.h class MyAPI { public: static int GetMaxNameLength(); ...
