Im trying to get the output transferred to a txt file. Each time i run it the way it is, it only shows a repetition of the first generated random number. I want all the random x_values and y_values to be shown in the text file. Can someone please tell me what i'm doing wrong? I've been doing this for about 3hrs, and I havent been able to correct my mistake. Whenever I use the cout function (cout << " x = " <<x_value<< " y = " <<y_value<< endl, it prints out all the random numbers. But i want it to be in a text file. Thanks
