7. How to use Substring in Different Programming languages

C++ #include #include using namespace std; // Drivers code int main() { string original_string = "Hello, World!"; string substring = original_string.substr(0, 5); cout << "Substring: " << substring << endl; return 0; } C #include #include int main() { char original_string[] = "Hello, World!"; char substring[6]; strncpy(substring, original_string, 5); substring[5] = '\0'; printf("Substring: %s\n", substring); return 0; } Java public class SubstringExample { public static void main(String[] args) { String originalString = "Hello, World!"; String substring = originalString.substring(0, 5); System.out.println("Substring: " + substring); } } Python original_string = "Hello, World!" substring = original_string[0:5] print("Substring:", substring) C# using System; class Program { static void Main() { // Original string string originalString = "Hello, World!"; // Extracting a substring from the original string // Starting from index 0 and taking 5 characters string substring = originalString.Substring(0, 5); // Printing the extracted substring Console.WriteLine("Substring: " + substring); } } Javascript let originalString = "Hello, World!"; let substring = originalString.substring(0, 5); console.log("Substring: " + substring);...
