How to use const array parameter in function with C

Answer 1

#include <stdio.h>

void f(const double arr[static 10], int size) {
    for (int i = 0; i < size; i++) {
        // arr[i] = 9; // error: assignment of read-only location
        printf("%lf\n", arr[i]);
    }
}

int main(void)
{
    double arr[10] = {2.4, 0.1, 4.8, 4.67};
    
    f(arr, 10); 
}
