C++ | Copy and Move File
Hello peeps! Lord Hypersonic greets you. Today I am presenting you a C++ program to copy and move a file from one location to another location. The algorithm is simple and I will also try my best to explain the algorithm as simple as I can 😛.
My source code is slightly longer because it contains some features which you will love. Why I have not mentioned them in the algorithm? Because they are so simple to understand that anyone can understand it by just reading it. The source code is self-explanatory.
Algorithm
There are two functions, one function can copy a file from one location to another location second function can move the file from one location to another. We will try to understand both functions one by one.
fileCopy(string file, string source, string destination) // Function to copy file.
1. First, replace every "\" with "/" in strings source and destination.
2. Now check that if "/" is present at the end of both strings (source and destination).
2.1. If not present then add "/" at the end of both strings.
3. Make string source equal to source + file ( source = source + file).
4. Make string destination equal to destination + file ( destination = destination + file).
5. Now open file "source" as binary and copy it's to "destination".
That's it for this function 😜. The next function is similar to this but there is a slight difference.
fileMove (string file, string source, string destination) //Function to move a file.
Do whatever you have done for fileCopy() function and after copying file delete the source file and this is how you can make a function to move the file 😜.
