C 中 &array 和 &array[0] 的区别

C语言中的数组与指针：&array和&array[0]的区别

c
#include 
int main() {
    int array[5] = {1, 2, 3, 4, 5};
    
    printf("Address of the array: %p%
", &array);
    
    return 0;
}

c
#include 
int main() {
    int array[5] = {1, 2, 3, 4, 5};
    
    printf("Address of the first element: %p%
", &array[0]);
    
    return 0;
}

c
#include 
int main() {
    int array[5] = {1, 2, 3, 4, 5};
    
    // Using &array
    int *ptr1 = &array;  // This line will generate a warning
    
    // Using &array[0]
    int *ptr2 = &array[0];
    
    // Accessing elements using pointers
    printf("Value at &array: %d%
", *ptr1);  // This line may lead to unexpected behavior
    printf("Value at &array[0]: %d%
", *ptr2);
    
    return 0;
}
