Main must be written as

A. The first function in the program
B. Second function in the program
C. Last function in the program
D. Any where in the program

(A)

main can be written any where in the program.To be frank main is a user defined word and it is a platform to call any function.

i think  main is a library function  and not a user defined function however it can be placed anywhere.

Its not a must that main must the first function to be written but it is the first function executed.

perfectly speaking main() is a fun in which all the program exists so A. THE FIRSTFUN IN THE PROGRAM . IS THE RIGHT ANSWER

ans:D)any where in the pgm
Becoz after the main only the execution starts.

Main is the Only function that will execute at the start, so it doesnt matter where ever the main can be placed. But there can't be any other function inside main function...

Any where in the program

D. Any where in the program.
