Insert String in Middle of Another

Write a C++ program to insert a given string into middle of the another given string of length 4.

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

// Function 'test' modifies a string by inserting 'word' into 's1' at index 2
string test(string s1, string word)
{
    // Concatenates the substring of 's1' from index 0 to 1, 'word', and the substring of 's1' from index 2 to the end
    return s1.substr(0, 2) + word + s1.substr(2);
}

// Main function to test the 'test' function
int main() 
{
    // Displays the output of the 'test' function for different string inputs
    cout << test("[[]]", "Hello") << endl;  // Output: "[[Hello]]" (inserts "Hello" at index 2 of "[[]]")
    cout << test("(())", "Hi") << endl;     // Output: "((Hi))" (inserts "Hi" at index 2 of "(())")
    return 0;    
}

Sample Output:

[[Hello]]
((Hi))
