{
std::string str ("This is an example sentence.");
std::cout << str << '\n';
str.erase (10,8);
std::cout << str << '\n';
str.erase (str.begin()+9);
std::cout << str << '\n';
str.erase (str.begin()+5, str.end()-9);
std::cout << str << '\n';
return 0;
}
Example 4: erase string c++
string& erase (size_t pos = 0, size_t len = npos);
Example 5: string erase character c++
#include <iostream>
#include <algorithm>
#include <string>
int main()
{
std::string s = "This is an example";
std::cout << s << '\n';
s.erase(0, 5);
std::cout << s << '\n';
s.erase(std::find(s.begin(), s.end(), ' '));
std::cout << s << '\n';
s.erase(s.find(' '));
std::cout << s << '\n';
}
