Answer / kumar
we can execute the program without main() also,but according
to the standardization of 'c' we must write the main
function.main is called as start-up function......during
compilation there will be a _start function by which the
execution starts.this _start calls main,after main execution
it returns to the _start function then it starts the
execution of the remaining code............

"Normally you are at liberty to give functions whatever
names you like, but ``main'' is special - your program
begins executing at the beginning of main. This means that
every program must have a main somewhere." Kernighan &
Ritchie - The C Programming Language 2ed. p.6

Answer / shreepad
Most new toolchains allow you to configure the entry point
other than main(). hence unless other wise specified, main
is the default entry point.
