What will be displayed by the following code?

```python
# Start of Code
def f(value, values):
v = 1
values[0] = 44
# End of function

t = 3
v = [1, 2, 3]
f(t, v)
print(t, v[0])
# End of code
```

A. 1 44
B. 1 1
C. 3 44
D. 3 1

Answer :

The code prints '3 44' because the function modifies the first element of the list 'v' to 44, but the variable 't' remains unchanged as integers are passed by value. The correct option is c.

The code in question is a Python program that demonstrates how variables are passed to functions and how they can be modified within those functions. The output that will be displayed by the code is a combination of the value of the variable t and the first element of the array v after the function f is called. The function f takes two arguments: value and values. Inside the function, v is set to 1, which is a local variable and does not affect the variables outside the function. However, values[0] = 44 changes the first element of the array v to 44. Because lists are mutable and passed by reference, the change to the list inside the function affects the list outside the function. However, since integers are immutable and passed by value, the change of v inside the function doesn't affect the variable t outside the function. Therefore, when we run print(t, v[0]), the output will be the original value of t, which is 3, and the new value of v[0], which is 44. The output will be 3 44.
