Question

{
    int i;
    for (i=0; i<n && a[i]!=x;i++);
    if (i==n) return -1;
    else return i;
}

A function call is made with the arguments as follows:

• $a[]=\{5, 32, 1, 9, 7, 2\}$

Answer 1

Seeing carefully at the end of for loop ; is used. So loop will terminate increasing value of i at 6.

And given condition if(i == n) will become true.

So this will return value -1.
