How to print all output of a program in text file in C++?

Joe Wilson

I mean I want to print the result of my program in a text file instead of showing the result in the console page, so please guide me to do that in C++.

Hi, thank you for your answer, by the way, someone told me that instead of comparing the files which have been printed out, it is better to print out the result as soon as one side of the graph get completed in the program that we have talked about, for example, as soon as compiler set one side of the graph like a --> b and it's weight , after that instead of use program to calculate the weight of edge of b -->a which is equal with a --> b just print out b --> a after that so it would reduce the time complexity what is your idea if it is possible please help me.

You can use the freopen function to redirect console output to a file.

For an example, check out:
