C++ String insert()

This function is used to insert a new character, before the character indicated by the position pos.

Syntax

Consider two strings str1 and str2, pos is the positon. Syntax would be :

Parameters

str : String object to be inserted in another string object.

pos : It defines the position at which new content is inserted just before the specified position.

subpos : It defines the position of first character in string str which is to be inserted in another string object.

sublen : It defines the number of characters of string str to be inserted in another string object.

n : It determines the number of characters to be inserted.

c : Character value to insert.

Example 1

Let's see the simple example.

     #include<iostream>
     using namespace std;
     int main()
    {
     string str1= "javat tutorial";
     cout<<"String contains :" <<str1<<'\n';
     cout<<"After insertion, String value is :"<<str1.insert(5,"point");
     return 0;
     } 

Output:

String contains : javat tutorial
After insertion, String value is javatpoint tutorial

Example 2

Let's the simple example of insertion when subpos and sublen are given.

#include<iostream>
using namespace std;
int main()
{
string str1 = "C++  is a language";
string str2 = "programming";
cout<<"String contains :" <<str1<<'\n';
cout<<"After insertion, String is :"<< str1.insert(9,str2,0,11);
return 0;
} 

Output:

String contains C++ is a language
After insertion, String is C++ is a programming language

Example 3

Let's see the simple example of insertion when number of characters to be inserted are given.

#include<iostream>
using namespace std;
int main()
{
string str = "Maths is favorite subject" ;
cout<<"String contains :"<<str<<'\n';
cout<<"After insertion, String contains :<<str.insert(9,"my",2);
return 0;
} 

Output:

String contains : Maths is favorite subject
         After insertion, String contains : Maths is my favorite subject
