Music CD burning project
I'm trying to write a music cd burning program but I'm getting a line before each output line in error. Any suggestions?

newtotalMinutes += totalMinutes;

Does anyone have any idea how to fix this problem?? ANY help would be greatly appreciated!
Do you want to have this:
That will draw a newline and flush the output buffer, so I guess that's not what you want.
endl here << newtotalSeconds << endl; ?That will draw a newline and flush the output buffer, so I guess that's not what you want.

Nope that is definitely not the problem. I don't get it!? I'm not sure where i'm going wrong.....
Here is the source code:
Here is the input file:
And here is the output file:
It should look like this:
Hopefully this helps!

Here is the input file:
1 310 2 462 3 259 4 273 5 627 6 535 7 300 |
And here is the output file:
Song Song Time Total Time Number Minutes Seconds Minutes Seconds ------ ------- ------- ------- ------- 1 0 1 0 1 2 5 50 5 51 3 0 2 5 53 4 7 42 13 35 5 0 3 13 38 6 4 19 17 57 7 0 4 18 1 8 4 33 22 34 9 0 5 22 39 10 10 27 33 6 11 0 6 33 12 12 8 55 42 7 13 0 7 42 14 14 5 0 47 14 There are 32 minutes and 46 seconds left on the CD. |
It should look like this:
Song Song Time Total Time Number Minutes Seconds Minutes Seconds ------ ------- ------- ------- ------- 1 5 10 5 10 2 7 42 12 52 3 4 19 17 11 4 4 33 21 44 5 10 27 32 11 6 8 55 41 6 7 5 0 46 6 There are 33 minutes and 54 seconds of space left on the 80-minute CD. |
Hopefully this helps!
My guess is you're looking for data that is smaller than your data type, like if you were looking for only a single byte but were using a 2 byte data type but poking in both bytes of that data. Similar errors can be made when using unions.
