What will be the value of x in the following code snippet?#include <...

Explanation:

printf() Return Value:
- The printf() function returns the number of characters printed (excluding the null character) if successful.
- In this code snippet, "Hello" has 5 characters.

Value of x:
- The value of x in this code snippet will be the number of characters printed by the printf() function, which is 5 for "Hello".

Output:
- The code snippet first prints "Hello" using printf() with x storing the return value (5).
- Then it prints the value of x using printf() with the format specifier "%d", which will print the value of x (5).

Therefore, the output will be "Hello 5". The value of x in this code snippet is 5.
