C++ Exercises: Create a new string of the first half of a given string of even length
First Half of Even-Length String
Write a C++ program to create the string of the first half of a given string of even length.
Sample Solution:
C++ Code :
#include <iostream> // Include the input/output stream library
using namespace std; // Use the standard namespace
// Function definition to return the first half of the input string
string test(string s1) // Function named 'test' accepting a string parameter 's1'
{
return s1.substr(0, s1.length() / 2); // Return a substring from index 0 to half the length of the input string 's1'
}
// Main function - entry point of the program
int main()
{
cout << test("Hello") << endl;
cout << test("Hi") << endl;
return 0; // Indicate successful completion of the program
