answer
flag
question
Consider the following code. (Assume that all variables are properly declared.)cin >> ch;while (cin){ cout << ch; cin >> ch;}This code is an example of a(n) ____ while loop.
answer
EOF-controlled
question

answer
looping
question
Suppose j, sum, and num are int variables, and the input is 26 34 61 4 -1. What is the output of the code?sum = 0;cin >> num;for (int j = 1; j <= 4; j++){ sum = sum + num; cin >> num;}cout << sum << endl;
answer

question
What is the output of the following loop?count = 5;cout << 'St';do{ cout << 'o'; count--;}while (count <= 5);
