The array of C language is a parameter to pass a pointer

#include <stdio.h>
int test_size(int data[]){
	printf("sizeof(data) = %ld\n",sizeof(data)); //sizeof(data) = 8
}
// Be careful ： All pointer types are occupied 8 Bytes , Regardless of 32 position , still 64 Bit system , Is so 

int main(){
	int count[] = {1, 2, 3, 4, 5};
	printf("sizeof(count) = %ld\n", sizeof(count));//sizoef(count) = 20

	test_size(count);

	return 0;
}
