Which of the following for loop declaration is not valid Mcq?

Hence, the correct answer is option (b). 15) Which of the following for loop declaration is not valid? Then the code would execute. But without assigning the value of i/9 to a variable, it would not execute, and an exception is thrown, as shown below.

Can we use for loop inside constructor in C++?

How are functions defined inside a class in C++?
