The current string content is extended by inserting some additional content at a specific location within the string content (this position is determined by either pos1 or p, depending on the function version used).The arguments passed to the function determine the content that is inserted:string& insert ( size_t pos1, const string& str );    Inserts a copy of the entire string object str at character position pos1.string& insert ( size_t pos1, const string& str, size_t pos2, size_t n );    Inserts a copy of a substring of str at character position pos1. The substring is the portion of str that begins at the character position pos2 and takes up to n characters (it takes less than n if the end of str is reached before).string& insert ( size_t pos1, const char * s, size_t n );    Inserts at the character position pos1, a copy of the string formed by the first n characters in the array of characters pointed by s.string& insert ( size_t pos1, const char * s );    Inserts at character position pos1, a copy of the string formed by the null-terminated character sequence (C string) pointed by s. The length of this character sequence is determined by the first ocurrence of a null character (as determined by traits.length(s)).string& insert ( size_t pos1, size_t n, char c );    Inserts a string formed by a repetition of character c, n times, at the character position pos1.iterator insert ( iterator p, char c );    Inserts a copy of character c at the position referred by iterator p and returns an iterator referring to this position where it has been inserted.void insert ( iterator p, size_t n, char c );    Inserts a string formed by the repetition of character c, n times, at the position referred by iterator p.template<class InputIterator> void insert (iterator p, InputIterator first, InputIterator last);    Inserts at the internal position referred by p the content made up of the characters that go from the element referred by iterator first to the element right before the one referred by iterator last.// inserting into a string#include <iostream>#include <string>using namespace std;int main (){  string str="to be question";  string str2="the ";  string str3="or not to be";  string::iterator it;  // used in the same order as described above:  str.insert(6,str2);                 // to be (the )question  str.insert(6,str3,3,4);             // to be (not )the question  str.insert(10,"that is cool",8);    // to be not (that is )the question  str.insert(10,"to be ");            // to be not (to be )that is the question  str.insert(15,1,':');               // to be not to be(:) that is the question  it = str.insert(str.begin()+5,','); // to be(,) not to be: that is the question  str.insert (str.end(),3,'.');       // to be, not to be: that is the question(...)  str.insert (it+2,str3.begin(),str3.begin()+3); // (or )  cout << str << endl;  return 0;}Output:to be, or not to be: that is the question...

Define a class to represent a bank account. In the class, include the following members:Data members: name of the depositor, account number, type of account, and balance amount in the account.Member functions: to assign initial values, to deposit an amount, to withdrawal an amount after checking the balance, and to display the name and balance.Write main() code to test your class?

What will be the output of the program ?#include<stdio.h>#include<string.h>int main(){ char str1[20] = "Hello", str2[20] = " World"; printf("%s\n", strcpy(str2, strcat(str1, str2))); return 0;}
