c++ create a formatted text with x lines and y columns from a string of words code example

Example: I need to write an int function in which there are only cout statements and if I return 0/1 it prints them too.

/*
 * First C++ program that says hello (hello.cpp)
 */
#include <iostream>    // Needed to perform IO operations
using namespace std;
 
int main() {                        // Program entry point
   cout << "hello, world" << endl;  // Say Hello
   return 0;                        // Terminate main()
}                                   // End of main function
