Question
In C++ using File Processing to write a program that allows you to write stats of a monster and save it to a file. (in text format) (Things like Name, Hit Points, Minimum damage and Maximum damage.) Allows you to open the file and read the stats of the monster. (Print what was read onto the screen.) Allow the user to decide what file to open (just type in the filename)
Allow the program to load the stats of two monsters and let them battle it out.
1. Create monster stats
2. Ask the user if creating or loading (ask the user the file name)
3a. If loading open file for reading read stats in from file print stats to screen
3b. If creating open file for writing write stats to file - make sure to leave spaces or returns between variables, so all values do not get smooshed together
Explanation / Answer
/**************** Sample Output ****************/
// store the file with name monster.cpp
// $ g++ monster.cpp
// $ ./a.out
// Enter 1 for Creating and 2 for Loading
// 1
// Enter name, hit points, minimum damage and maximum damage
// dog 8 12.67 45.2
// $ cat monster_stats.txt
// dog 8 12.67 45.2
// $ ./a.out
// Enter 1 for Creating and 2 for Loading
// 2
// dog 8 12.67 45.2
