How to return more than one integer from a function in C?

Question

I want to return more than one integer from a function that is called from main, also in which series will I obtain those numbers. Can you please explain

Answer 1

1) You can make use of a bigger data structure like array or make a custom data type ( maybe a struct of all those integers ) and return one variable of that type.

2) ( as already suggested by Jay Matthews ) Instead of passing the values of the variables, you can pass the addresses to the function so that function may directly alter the original variables.

Answer 2

You can use dynamically allocated array or you can use struct.
And you can also pass pointer to the function so that it can modify your variables in main function

Answer 3

You can easily do it via command line arguments

Answer 4

int* fun(){}

Signature expects a pointer to int. Int can be an array (multiple ints)
