Consider the following C++ statements :

int x;
int& y = x;

The statements

y = 25;
x = 2*x + 30;

update the value of x and y as :

निम्नलिखित C++ कथनों पर विचार करें :

int x;
int& y = x;

कथन

y = 25;
x = 2*x + 30;

x और y के मान को अपडेट करता है :

1. Ay = 25, x = 25
2. By = 25, x = 80
3. Cy = 25, x = 30
4. Dy = 80, x = 80

Show answer & explanation

Correct answer: D. y = 80, x = 80

Explanation

y is a reference (alias) of x. y = 25 makes x = 25; then x = 2 × 25 + 30 = 80, and y shows the same 80.

y, x का रेफरेंस (उपनाम) है। y = 25 से x = 25; फिर x = 2 × 25 + 30 = 80, और y भी 80।
