The question presents a C++ program that reads a line of numbers separated by spaces and sums them. The key steps are as follows: - The program starts by printing the prompt: Enter numbers separated by spaces: - It then reads a full line from standard input into numList using getline(cin, numList). - The string numList is assigned to an istringstream named inSS via inSS.str(numList). - The loop while (inSS >> number) iterates over the integers parsed from the stringstream. Each successful extraction of an int updates number and accumulates it into sum with sum = sum + number. - When there are no more numbers to read, the loop ends, and the program prints the result with cout << "Sum: " << sum << endl;. Now, evaluating the specific input 10 20 30 40 50: - The input line contains five integers: 10, 20, 30, 40, and 50. - The loop reads each number in turn and adds them to sum: 0 + 10 = 10, then 10 + 20 = 30, then 30 + 30 = 60, then 60 + 40 = 100, then 100 + 50 = 150. - After processing all numbers, sum equals 150. Regarding the overall program output: - The program first prints the prompt "Enter numbers separated by spaces: ". - After you enter the numbers and press enter, it prints the computed result prefixed by "Sum: ", yielding a final output line of "Sum: 150" followed by a newline. - If someone considers the exact console output including the prompt, it would be the prompt text before input and the line "Sum: 150" after processing the input. Note on the provided data: there are no answer options supplied in the question. Consequently, there is no multiple-choice option to evaluate against; the analysis focuses on what the code does and what the resulting output would be for the given input.
