Question

x.Hm Im working this program by parts and I could really use someone help. Ive been tryin to figure out the how to delete a line that was put into a string from a file line because it has invalid data in it. Let me show you a input file so you can see what i mean: sample input:
Gates, William ,H, 1.89 Jobs,Steven,P,2.56 Brin , Sergey , , 3.89 Page, Lawrence ,, 3.77    Buffett, Warren, E, 3.34 Short, Sue, , 3.11 Cisneros, Juan, G, 3.67 Andrew, T, 5.67
Do you see where it says andrew, T, 5.67 ? well at scan time I would like to ignore that line and continue to the next one. After I have done so, my program will produce the folllowing output file: output file: Highest gpa: 3.89 Average gpa: 3.18 (only 7 numbers were inputted since one of them were delete it) lowest gpa: 1.89 
 William H. Gates 1.89Steven P. Jobs 2.56Sergey Brin 3.89Lawrence Page 3.77Warren E. Buffett 3.34Sue Short 3.11Juan G. Cisneros 3.67
Thats what I would like it to do but I get this: my outoutfile: Highest gpa: 5.67 Average gpa: 3.49 Lowest gpa: 1.89
