I'm having trouble getting this code to work; can
you tell me what's wrong? Here's what the compiler says:
bogus.c:1:20: iostream: No such file or directory (ENOENT)
bogus.c:2:18: string: No such file or directory (ENOENT)
bogus.c:3:18: vector: No such file or directory (ENOENT)
bogus.c:4: parse error before "namespace"
bogus.c:4: warning: type defaults to `int' in declaration of `std'
bogus.c:4: ISO C forbids data definition with no type or storage class
bogus.c: In function `main':
bogus.c:8: `string' undeclared (first use in this function)
bogus.c:8: (Each undeclared identifier is reported only once
bogus.c:8: for each function it appears in.)
bogus.c:8: parse error before "data"
bogus.c:9: warning: ISO C forbids nested functions
bogus.c:9: syntax error before '<' token
bogus.c:10: `true' undeclared (first use in this function)
bogus.c:12: `cout' undeclared (first use in this function)
bogus.c:13: warning: implicit declaration of function `getline'
bogus.c:13: `cin' undeclared (first use in this function)
bogus.c:13: `data' undeclared (first use in this function)
bogus.c:16: `virtual_memory' undeclared (first use in this function)
bogus.c:18: parse error before '/' token
bogus.c:12: warning: statement with no effect
bogus.c:20: warning: control reaches end of non-void function
(An oddity: The lines of diagnostic messages outnumber
the lines of source code.)
