What parameters should be passed in calling integer or character array functions

• Say first conclusion
  // Experimental array , Whether it's a character array or an array
  // At call time , Is to pass in the array address
  // The function parameter of the call can be int A ,int A[ ]
  //int A[ ] This is because the array name is the first address of the array
  // The pointer type is int, A pointer refers to an address
  // At the same time, you can write fun(A)
  // or fun(&A[1]) What's going on here is The address of the second array element
  // The same goes for character arrays , The following is a running example
• The following is the running result of each code

 #include"stdio.h"
 void fun(int A[]){
    
 for(int i=0;i<3;i++)
 printf("%d\n",A[i]);
 }
 
 int main(){
    
 int A[3]={
    1,2,3};
 fun(&A[1]); 
	  return 0;
	  }
