In JavaScript, you can select an HTML table row using the  getElementsByTagName  method to get all the  <tr>  elements in the table, then use the  item  method or the  []  operator to select a specific row. Once you have selected the row, you can use the  insertCell  method to add new cells to the row and the  innerHTML  property to insert data into the cells. Here's an example of how you can select the first row of an HTML table with the id "myTable" and insert new data into it: // Get the table   var table = document.getElementById("myTable");     // Get the first row of the table   var row = table.getElementsByTagName("tr")[0];     // Insert a new cell at the end of the row   var newCell = row.insertCell(-1);     // Insert some data into the new cell   newCell.innerHTML = "New Data";   You can also use the querySelector method to select the table and the row let ta...

Yes, it is possible to call a function within another function in C and C++. This is known as nested function calls. Here's an example of a C++ program that calls a function within another function: #include <iostream>     void print_hello() {   std::cout << "Hello, World!" << std::endl;   }     void print_greeting() {   std::cout << "Welcome to the program!" << std::endl;   print_hello(); // function call   }     int main() {   print_greeting();   return 0;   }   In this example, the  print_hello()  function is called within the  print_greeting()  function. The  print_greeting()  function first prints a message to the console, and then calls the  print_hello()  function which prints a different message. Functions can be nested as many levels as necessary, but it's important to keep in mind that deeply nested function calls ...
