reading in integers from a file

sky3 (55)
for the life of me i cannot figure out why this wont just read in and output correctly. when i cout it, it wont get the third number and i end up with:
2800000
0
24
input is 2800000.00 24 8.40

It's probably because you declared intBalance to be an integer. So, when it reads the file, it stops at the point. annInterest reads the 00, and then numof payments reads the 24. Try changing intBalance to a float and annInterest to the integer.

when i declared it as a float, it wouldnt read the entirety of 280000?
