hey i got some c homework due Monday and I'm stuck. please help me. I'm going to mark the error lines with **** in place of a tab. build errors are at the bottom. i will be eternally grateful for any insight.

C:\Documents and Settings\Luigi Mario\Desktop\patrick allard gps continued source[1].cpp(88) : error C2062: type 'double' unexpected

C:\Documents and Settings\Luigi Mario\Desktop\patrick allard gps continued source[1].cpp(90) : error C2065: 'difflatt' : undeclared identifier

C:\Documents and Settings\Luigi Mario\Desktop\patrick allard gps continued source[1].cpp(92) : warning C4244: '=' : conversion from 'double' to 'int', possible loss of data

not that i get these errors when i build but not when i compile
