what are loops

Answer 1

A loop is a function that continues to run until a certain condition evaluates to false.

while() is a loop. Example:

int x = 0;
while (x != 6)
{
std::cout << x << "\n";
x++;
}

Output will be:

0
1
2
3
4
5

for() is also a loop. Example:

int x = 1;
for (int y = 1; y <= 5; y++)
{
std::cout << x << "\n";
x *= y;
}

Output will be:

1
2
6
24
120
