An array is defined with the following statement in a file, file1.c

        int a[ ] = { 1, 2, 3, 4, 5, 6 };

In another file, file2.c, the following code snippet is written to use the array a:
extern int a[];
int size = sizeof(a);
What is wrong with the above code snippet?

Which statements are correct for the keyword register?

Which one is not a type of operator ?

What would be printed on the standard output as a result of the following code snippet? char i = 'A'; char *j; j = & i; *j = *j + 32; printf('%c',i);

Which standard function is used to deallocate memory allocated by the malloc() function?

What will be printed on the standard output as a result of the following code snippet? void main() { char arr[] = {'R','A','M'}; printf('%d',strlen(arr)); }

What will happen when the following code is executed? { int num; num =0; do {-- num; printf('%d\n', num); num++; } while (num >=0); }

Given the following array: int a[8] = {1,2,3,4,5,6,7,0}; what would be the output of printf('%d',a[4]); ?

What will be printed on the standard output as a result of the following code snippet? void main() { int arr[5]={1,2,3,4,5}; printf('%d\n', *(arr+4)); }

What will happen when the following code is executed? void main() { char arr1[] = 'REGALINT'; char arr2[10] = 'REGALINT'; printf('%d,',sizeof(arr1)); printf('%d',sizeof(arr2)); }

What would be printed on the standard output as a result of the following code snippet? main() { int a[5] = {1,4,5,6,9}; printf('%d\t', *a); //Line 1 printf('%d', *++a); //Line 2 return 0; }
