Why does the program only give an output if defined in main (and how can I change this)?

Question

I tried to run this

int array( void )
{
    char text[12] = {  112, 114, 111, 103, 112, 0 };
    int i;
    for(i = 0; text[i]; i = i +1)
        printf("%c", text[i]);
    printf("\n");
    return 0;
}

int main( void )
{
    int array(void);
    return 0;
}

and the program runs but I am getting no result. Now when I use the main function to define the program:

int main( void )
{
    char text[12] = {  112, 114, 111, 112, 0 };
    int i;
    for(i = 0; text[i]; i = i +1)
        printf("%c", text[i]);
    printf("\n");
    return 0;
}

I get the result progr(as wanted). I already searched but the only related questions I find are about using main as a function name and wrong outputs. Maybe I am searching the wrong way but I would be pleased if someone could answer this.

Since the function returns int, You should've assigned its return value to int too. OR
You can just call it normally with only its name because it always returns a 0 constant.

int i = array(); // i = 0
// or
array();

It's just printing and its value is always 0.
Then I suggest making it void instead because You'll need to call it by name only.

#include <stdio.h>
void array()
{
    char text[12] = {  112, 114, 111, 103, 112, 0 };
    for(int i = 0; text[i]; i++)
        printf("%c", text[i]);
    printf("\n");
}
int main()
{
    array();
    return 0;
}

Note that You can't assign the type void to anything.
