Remove spaces from std::string in C++

In this program we will see how to remove the spaces from a std::string in C++. To remove this we will use the remove() function. With this remove() function it takes the beginning and end of the iterator, then takes the third argument that will be deleted from that iterator object.

Input: A string "This is C++ Programming Language"
Output: "ThisisC++ProgrammingLanguage"


Step 1: Get the string
Step 2: Remove spaces from the given string using remove() function.
Step 3: Return string.

Example Code

 Live Demo

using namespace std;
main() {
   string my_str = "This is C++ Programming Language";
   cout << "String with Spaces :" << my_str << endl;
   remove(my_str.begin(), my_str.end(), ' ');
   cout << "String without Spaces :" << my_str;


String with Spaces :This is C++ Programming Language
String without Spaces :ThisisC++ProgrammingLanguage
