Question

Which of the following is the final line of output generated in the code segment below?

int x = 3415263;
int ct = 0;

while(x > 0)
{
if(x % 2 == 0)
ct++;

printf("x: %d ct: %d\\", x, ct);

x = x / 10;

}

printf("ct: %d\\", ct);

Answer 1

The final line of output from the provided C code snippet, which counts the number of even digits in the integer 3415263, will be 'ct: 3', after evaluating and counting the even digits (4, 2, 6) in the given number.

Step-by-step explanation:

The student is asking about the final output of a given code snippet in C. The code executes a while loop that checks each digit of the number 3415263 to see if it's even, increments a counter ct if so, prints the values of x and ct on each iteration, and divides x by 10 at the end of each loop. Eventually, x becomes less than 1, the loop ends, and the final printf statement is executed.

The final line of the output would be the value of ct after evaluating all the digits of x. If we evaluate the loop, it would count the even numbers (4, 2, 6) and increment ct three times before the loop terminates, resulting in the final line of output being: ct: 3.
