Erase String C++ Code Example

Example 1: 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); // Erase "This "     std::cout << s << '\n';       s.erase(std::find(s.begin(), s.end(), ' ')); // Erase ' '     std::cout << s << '\n';       s.erase(s.find(' ')); // Trim from ' ' to the end of the string     std::cout << s << '\n'; }

Example 2: erase string c++

string& erase (size_t pos = 0, size_t len = npos); /* pos Position of the first character to be erased. If this is greater than the string length, it throws out_of_range. Note: The first character in str is denoted by a value of 0 (not 1). len Number of characters to erase (if the string is shorter, as many characters as possible are erased). A value of string::npos indicates all characters until the end of the string. */
