do {
cout << "Hello.\n";
num ++;
} while (num < 4);
while (num < 7){
cout << "Hello.\n";

What is int board[3][4];?
int a = 5, b = 10;
int temp;
Given the above code, these are three lines of code that swap the values of a and b.
What is temp = a; a = b; b = temp;?
int main () {
int a = 100, b = 200;
mySwap(a,b);
return 0;
}
void mySwap(int x, int &y) {
int temp = x;
x = y;
y = temp;
}
The value of a and b after the above lines of code.
What is 100?
ifstream inputFile("input.txt");
if (!inputFile) {
cerr << "Error opening the file." << endl;
return 1;
}
int number;
while (?) {
inputFile >> number;
}
The condition represented by the ? in the above code that allows the user to read until the end of the file.
What is !inputFile.eof()?
