In Python, if

a = [10,12,15,16],

what is the value of a after

for (i in len(a)):

a[i]=a[i]+1

the stmt is meaningless and should be changed to "for (i in range(len(a))):"

[11,13,16,17]

the stmt is meaningless and should be changed to "for (i in a):"

a is immutable and hence illegal

cannot assign a to i

5.

MULTIPLE CHOICE QUESTION

1 min • 1 pt

Stmts like a = a++ are best avoided in C++ because

cannot have a as lvalue and rvalue in the same stmt

it can get confused as (a=a)++

it has unsequenced updates

it is meaningless as a cannot be equal to its incremented value

MULTIPLE CHOICE QUESTION

1 min • 1 pt

int vect[] = {10, 20, 30, 40};

for (int& x: vect) x = x + 5;

What is the value of vect?

cannot be computed as x does not have an initialization

as vect is not updated, value remains same as before

{15,25,35,45}

vect[] is not a correct decl & hence will not compile
