Thread: Read one and multiple bytes in function

following approach work for me

Code:

#include<stdio.h>    

int read (unsigned int N, unsigned int *p);
  
int read (unsigned int N, unsigned int *p)
{
    int i;
	   for (int i = N-1; i >= 0; i--) {   
	   printf("\n read address %p \n ", (p + N-1));   
       printf("value store at this address is = %d \n", *( p + N-1));
       --p; 	   
    }    
}
 
     
int main()    
{    
    int s;  int N = 5 ;  // length of array     
    
    //Initialize array     
    int Data[] = {1, 2, 3, 4, 5};     
         
    printf("Original array: \n");    
    for (int i = 0; i < N; i++) {  
        printf("%p  = %d \n", &Data[i], Data[i] ); 	 
    }      
        
    printf("\n");    
        
    printf("Array in reverse order: \n");    
    //Loop through the array in reverse order    
    for (int i = N-1; i >= 0; i--) {   
        printf("%p  = %d \n", &Data[i], Data[i] ); 	 
    }
     s= read (N, Data);	
    return 0;    
}

Original array:
0061FF0C = 1
0061FF10 = 2
0061FF14 = 3
0061FF18 = 4
0061FF1C = 5


Array in reverse order:
0061FF1C = 5
0061FF18 = 4
0061FF14 = 3
0061FF10 = 2
0061FF0C = 1


read address 0061FF1C
value store at this address is = 5


read address 0061FF18
value store at this address is = 4


read address 0061FF14
value store at this address is = 3


read address 0061FF10
value store at this address is = 2


read address 0061FF0C
value store at this address is = 1
