This is about the first question i.e,
* Is there any difference when a C program runs in a C++ compiler?
I was surprised to know there is no difference between handling of .c
file and .cc file by a C++ compiler. To test this, i wrote just three
lines in a program:
void main()
{
}
i compiled this program using Dev C++ environment first as a .cc
program and then as a .c program.
while compileing it as .cc, i got error message that main() can return
only an int.
while compiling it as .c, i got only a warning.
on further investigation, i found that while Dev C++ uses g++ to
compile .cc file, it uses gcc to compile .c file. so what is the
difference between gcc and g++. as per my understanding, g++ is just a
script that invokes gcc only, though i am not very sure.
