What is the output of the following code snippet?#include <iostream...
Understanding the Code Snippet
The given code snippet is a simple C++ program that demonstrates the behavior of the post-increment operator (`x++`) and how it interacts with the output stream.
Code Breakdown
- Variable Initialization:
cpp
int x = 10;
The integer variable `x` is initialized to `10`.
- Output Statement:
cpp
std::cout < x="" />< "="" "="" />< x++="" />< />
This line prints two values: the current value of `x` and the value of `x` after the post-increment.
Post-Increment Explained
- Post-Increment Behavior:
The expression `x++` uses the current value of `x` (which is `10`) and then increments `x` by `1`. Thus, during the evaluation of the output statement:
- The first `x` outputs its current value (`10`).
- The second `x++` outputs `10` as well, but `x` will now be `11` after this operation.
Final Output
- The output will be:
10 10
- After the execution, `x` will be `11`, but this does not affect the output on the console.
Correct Answer
Given the above explanation, the correct output of the code snippet is option b) 10 10.
This highlights the importance of understanding operator precedence and the distinction between pre-increment and post-increment in C++.

What is the output of the following code snippet?#include <iostream...
The post-increment operator increases the value of x after printing, so x is printed as 10, and then it becomes 11.
