Programming and Data Structures - Arrays
4. If x is an array of integer, then the value of &x[i] is same as
- Option : A
- Explanation : x+i means increment in value of x not in address of x so it cant represent address of x. &x[i] means address of the ith element. So &x[i-1] defines address of i-1 element .sizeof(int) defines size of an element So &x[i-1] + sizeof(int) means address of i-1 element plus size of an element that means address of ith element. It cant be option c as x+i is not representing any address. x+i means increment in value of x not in address of x so it cant represent address of x. So option (A) is correct
- Option : A
- Explanation : scanf("%s", S) only scans first parameter of input stream. So Option A is correct.
