C++/String/string erase
Erase a range of characters using an overloaded version of erase()
#include <string>
#include <algorithm>
#include <iostream>
using namespace std;
int main ()
{
string strSample ("Hello String!");
strSample.erase (strSample.begin (), strSample.end ());
if (strSample.length () == 0)
cout << "The string is empty" << endl;
return 0;
}
string.erase(6,9)
#include <iostream>
#include <string>
using namespace std;
int main()
{
string str1("String handling C++ style.");
string str2("STL Power");
cout << "Initial strings:\n";
cout << "str1: " << str1 << endl;
cout << "str2: " << str2 << "\n\n";
// demonstrate erase()
cout << "Remove 9 characters from str1:\n";
str1.erase(6, 9);
cout << str1 <<"\n\n";
return 0;
}
/*
Initial strings:
str1: String handling C++ style.
str2: STL Power
Remove 9 characters from str1:
String C++ style.
*/
Use erase to remove all characters from (and including) location 6 through the end of string1
#include <iostream>
using std::cout;
using std::endl;
#include <string>
using std::string;
int main()
{
string string1( "abcedfghijklmnopqrstuvwxyz" );
cout << "Original string:\n" << string1 << endl << endl;
string1.erase( 6 );
cout << "Original string after erase:\n" << string1
<< "\n\nAfter first replacement:\n";
return 0;
}
/*
Original string:
abcedfghijklmnopqrstuvwxyz
Original string after erase:
abcedf
After first replacement:
*/
