Conflicting Types Error when Passing 2D Array to Function in C-CodePudding

I am trying to pass a 2D array to a function that I have defined in my program, but for some reason, I am continuously getting an error about conflicting types for the function call and definition. I am not entirely sure what could be causing the issue since I have not only included the right header, but also used the proper parameter type in the function indicating that it is a 2D array. Below is the code that I am writing.

#include <stdio.h>
#include <stdbool.h>

int main()
{
    char array[6][6] = {
        {'.', '.', '.', '.', '.', '.'},
        {'.', '.', '.','.', '.', '.'},
        {'.', '.', '.', '.', '.', '.'},
        {'.', '.', '.', '.', '.', '.'},
        {'.', '.', '.', '.', '.', '.'},
        {'.', '.', '.', '.', '.', '.'}
    };
    
    bool success = testFunction(array, 0, 1);

    return 0;
}


bool testFunction(char array[][6], int i, int j){
    return true;
}

And this is the error that I receive after running the program:

main.c:21:6: error: conflicting types for ‘testFunction’
   21 | bool testFunction(char array[][6], int i, int j){

It's really confusing me and after looking at previous posts on StackOverflow I cannot seem to find what could be causing this issue. I know this problem could possibly be solved if I converted the array into a pointer, but is it not possible to pass 2D arrays to function? If anyone could help me find a way to solve this, I'd truly appreciate it. Thank you.

CodePudding user response：

You need to define it before the main function or put there the function prototype

bool testFunction(char array[][6], int i, int j);
