What will happen when the following code is run: int x; while(x<100) { cout<
-
The computer will output "0123...99"
-
The computer will output "0123...100"
-
The output is undefined
-
Don't know
In C++, local variables like int x are not automatically initialized to zero. Reading from an uninitialized variable leads to undefined behavior, meaning the initial value of x is unpredictable and the output of the loop is completely undefined.
To answer this question, you need to understand how the code snippet works.
The code snippet initializes an integer variable x without assigning it a value. In C++, uninitialized variables have an undefined value. Therefore, the initial value of x is unknown.
Next, the code enters a while loop that continues as long as x is less than 100. Inside the loop, the code prints the value of x using `cout<
