In this example we read from a Ruby file inside C. The Ruby code will print what you pass as an argument and what class the passed in value is. In this case we are declaring a variable new_ary of data type mrb_value. Then we are initializing it with the mrb_ary_new function which only takes an mruby state as an argument.
```C
#include <stdio.h>
#include <mruby.h>
#include "mruby/array.h" // Need the array header.
In this example we read from a Ruby file inside C. The Ruby code will print what you pass as an argument and what class the passed in value is. In this case after initializing our array. We are declaring two variables with the mrb_int data type random_value1 & random_value2 and we initialize them 70 and 60 respectively. Then we use the mrb_ary_push function to push values those values into the array.
```C
#include <stdio.h>
#include <mruby.h>
#include "mruby/array.h" // Need the array header.

We are declaring two variables with the mrb_int data type random_value1 & random_value2 and we initialize them 70 and 60 respectively. Then we use the mrb_ary_push function to push values those values into the array. Now here in the Ruby files we add another method
called pop_ary that will return the array alone(just to be clean) and you should see the last element gone.
```C
#include <stdio.h>
#include <mruby.h>
#include "mruby/array.h" // Need the array header.
Returns a reference to an element of the array. Specified by the value given to mrb_int n.
#### Example
In this example we read from a Ruby file inside C. The Ruby code will print what you pass as an argument and what class the passed in value is. In this case we're declaring a variable ary_ref with the data type of mrb_value. Then we assign mrb_ary_ref to it getting new_ary's value at index 1.
```C
#include <stdio.h>
#include <mruby.h>
#include "mruby/array.h" // Need the array header.
ary_ref = mrb_ary_ref(mrb, new_ary, 1); // Gets the value of new_ary's second element at index 1.
mrb_value obj = mrb_load_file(mrb,fp);
/* Passing the value from ary_ref to the method method_name.*/
mrb_funcall(mrb, obj, "method_name", 1, ary_ref);
fclose(fp);
mrb_close(mrb);
return 0;
}
```
test.rb
```Ruby
class Example_Class
def method_name(a)
puts a
puts a.class
end
end
Example_Class.new
```
#### Result
After compiling you should get these results.
```Ruby
60
Fixnum
```
### mrb_ary_set
```C
void mrb_ary_set(mrb_state *mrb, mrb_value ary, mrb_int n, mrb_value val);
```
Sets a value to an index.
