Q1: What will be the output of the program ?

#include<stdio.h>

int main()
{
    int arr[1]={10};
    printf('%d\n', 0[arr]);
    return 0;
}

ANS:A - 1

Step 1: int arr[1]={10}; The variable arr[1] is declared as an integer array with size '2' and it's first element is initialized to value '10'(means arr[0]=10) Step 2: printf('%d\n', 0[arr]); It prints the first element value of the variable arr. Hence the output of the program is 10.
