yes i do you do but not everyone and most of them use c++ features and=20
write procedural code and they say  that that code is write in c
so they save with .c so ... some compilers do mistacke like borland 3.1=20
try this in a .c file
int dummy (int & a )  my collegs do and by default the file name is=20
noname00.cpp compile run ok.
After save in a.c compile error "not ok " and they stay about 10 min to=20
figure out until theacher said that they had to rename the file
