How to declare an array in a function and call the function in C -

i have assignment , cannot figure out part.

the assignment requires create 2 separate functions , call them in main. question syntax calling pointer array , how call function in main program? example,

int function_1(int x, *array); 

how call function_1? or lost here?

i should add anytime try , call function array, error: [warning] assignment makes pointer integer without cast [enabled default]

int function(int x, char *array) {      //do work      return 0; } 

and in main

int main() {     char arr[5] = {'a', 'b', 'c', 'd'};     int x = 5;     function(x, &arr[0]);     return 0; }
