Reading from text files (substrings)

[Faux]

I need help making two substrings(I think) to get the integer values (course hours, grade) for each course. I thought I had it but every time I ran the .exe it would crash after obtaining the name and major, so I deleted that code altogether. It'd be grand if someone can point me in the right direction here.

Text file reads:

Name:John Q. Student
Major:Basket Weaving

Stitching 102: 3 4
Cross Weaving 244: 3 3
Basket Fibers 287: 3 2
Basket Shapes 155: 3 3
