Answer 2

Answer:

1 main function can be used in a c program.

Explanation:

Main () in a c program is also considered as the function. Each and every C program should possess at least one function (preferably one main () function). But there are no limits on number of functions. A C program can contain any ‘number of functions’.

A function in C, can has the ability to call itself which is known as Recursion. One can define 2 or more main () functions in the source code. But only one of them will be compiled at a time.
