Examples at hotexamples.com: 1

The string erase function in C++ is used to delete characters from a string starting from a specific position. It takes two arguments: the starting position and the number of characters to delete.

Here are some examples:

Example 1:

#include 
#include 
using namespace std;

int main() {
    string str = "Hello, world!";
    str.erase(5, 7);
    cout << str << endl;
    return 0;
}

Output: "Hello!"

In this example, the erase function is used to delete the substring "world!" starting from the 5th position (index 4) of the string.

Package library: .

Example 2:

#include 
#include 
using namespace std;

int main() {
    string str = "abcdefghij";
    str.erase(3);
    cout << str << endl;
    return 0;
}

Output: "abcefghij"

In this example, the erase function is used to delete the character at the 3rd position (index 2) of the string.

Package library: .

Example 3:

#include 
#include 
using namespace std;

int main() {
    string str = "abcdefghij";
    str.erase(3, 2);
    cout << str << endl;
    return 0;
}

Output: "abcfghij" In this example, the erase function is used to delete 2 characters starting from the 3rd position (index 2) of the string. Package library: .
