What will be the output of the following C++ code? #include <iostr...
Explanation:

Struct Definition:
- The given C++ code defines a structure named 'student' with two members: an integer 'num' and a character array 'name' of size 25.

Main Function:
- Inside the 'main' function, an object 'stu' of type 'student' is created.
- The 'num' member of 'stu' is assigned a value of 123.
- The 'name' member of 'stu' is assigned the string "John" using the 'strcpy' function.

Output:
- The code then prints the value of 'stu.num' which is 123, followed by the value of 'stu.name' which is "John".
- Therefore, the output of the code will be:
123
John

Conclusion:
- The code successfully assigns values to the members of the 'student' structure object 'stu' and prints them to the console.
