I am am supposed to prompt the user to enter the text to open the file. I have the code bold so you can find it better. The original name of the file are follows: outfile.open("textout.out"); infile.open("textin.txt"); how do I implement this ask the user to enter the file and open these?
Stuck on this. I am am supposed to prompt the user to enter the text to open the file. I have the code bold so you can find it better.
The original name of the file are follows:
outfile.open("textout.out");
infile.open("textin.txt");
how do I implement this ask the user to enter the file and open these?
