C++ String erase()

This function removes the characters as specified, reducing its length by one.

Syntax

Consider a string str. Syntax would be:

str.erase(pos,len);
str.erase(itr);
str.erase(first,last);

Parameter

  • pos :It defines the position of the character which is to be removed.
  • len :It defines the number of characters to be erased.
  • Itr : It is an iterator to the character to be removed.
  • Range(first,last): It defines the range within the string to be removed.

#include<iostream>
using namespace std;
int main()
{
	string str="This is a java tutorial";
	str.erase(8,1);
	cout<<str;
	return 0;
}

Output:

Example 2

#include<iostream>
using namespace std;
int main()
{
	string str="java programming";
	str.erase(str.begin()+11);
	cout<<str;
	return 0;
}

Output:

Example 3

Let's see a simple example when the range is mentioned in a parameter:

#include<iostream>

int main()
{
	string str="This is an example of C and C++";
