I'm having problem understanding the concepts of ftell(),fseek etc.
i need to know
a)the general syntax of ftell() is ....n=ftell(file_pointer);
supppose for a file to which i have already written the following integers 1,2,3
and after having written the last integer i use ftell what should be the value of n ?
b) what exactly are they talking about when the tell that ftell returns the current position of the file?
c) when i write a integer or character to a file how many bytes of data has my compiler written ? on what does it depend?
