in C why do you had to compile the code with the
flag -lm
at the end. Why is it and what does this flag indicate?
Homework Answers
-l is used to link static library
-l<library name>
Reason for adding -lm because m stands for math
library which is already provided by C compiler and -l is
used to link that library so that we can access common math
functions like pow (power) , sin (Sine of angle) etc
Hence -lm flag is used.
Similary lets say we have created a library name with name as util
, so we can use -lutil to link our library

Will the following code compile? If not, why not? Assume it is using the standard namespaces, includes all necessary libraries and has a defined class called "MyClass" with a default constructor. vector <MyClass> vec; MyClass myClass; vec.push_back(myClass); Options: 1. No, vectors must push back data types, not instances of a data type 2. no, space was never allocated for the vector 3. no, you can not use a user defined data type at the data type for a vector 4....
