Good Evening, I'm trying to print information to a file with some basic information about a group of people, but when I use the fprintf function and add the \n or \r to the end of the format, the information is not printed on a new line in the text document I have opened. It is instead printing the information without ... |

What I have done is basically laid out a 10x10 table filled with zeroes in every position. Now what I want to do is have the user input a line number, and then fill in the 10 columns with actual numbers. Is there a command in C that will let me move the cursor to the next line without printing a ... |

If I did your homework for you, then you might pass your class without learning how to write a program like this. Then you might graduate and get your degree without learning how to write a program like this. You might become a professional programmer without knowing how to write a program like this. Someday you might work on a project ... |

If you open fout in a function -- in any function, even in main() -- , then it is only known within that function. To make it known to a function that main calls, you need to pass it as an argument to that function. A visual aid that we were given for figuring out scope is to view the entire ... |
