Question

Suppose j, sum, and num are int variables, and the input is 26 34 61 4 -1. What is the output of the following code?

sum = 0;
cin >> num;
for (int j = 1; j <= 4; j++)
{
sum = sum + num;
cin >> num;
}
cout << sum << endl;

Answer 1

The output of the code is 125.

Step-by-step explanation:

The output of the given code can be determined by working through the code step by step. Initially, the variable sum is assigned the value 0. Then, the program reads the first value of the input, which is 26, and assigns it to the variable num. In the for loop, the variable j starts at 1, and as long as j is less than or equal to 4, the loop continues iterating. Inside the loop, the value of num is added to the current value of sum, and a new value is read into num. After the loop completes, the final value of sum is printed, which will be the sum of the four numbers entered as input. In this case, the numbers entered are 26, 34, 61, and 4, resulting in a sum of 125. Therefore, the output of the code is 125.
