Why sizeof(array) and sizeof(&array[0]) gives different results?

Question

#include 
int main(void){
    char array[20];

    printf( \"\\nSize of array is %d\\n\", sizeof(array) );  //outputs 20
    printf(\"\\nSize of &         


        

Answer 1

sizeof(array) is giving you size of total array and sizeof(&array[0]) is giving you sizeof(char *)

Your question is perfect example of Array and pointer are not same. Array may act as pointer.Have a look here.
