After learning about the loops, now let's learn what are nested loops.
Instead of writing a statement again and again, we write it once in a loop.
We can also use a loop inside a loop and that is called nested loop.
Nested loop means a loop statement inside another loop statement. Thus, it is also called a "loop inside loop".
The inner loop executes completely whenever the outer loop executes.

Syntax:
for ( initialization; condition; increment ) {
for ( initialization; condition; increment ) {
// statement of inside loop
}
// statement of outer loop
}
Same can be done with a while loop and do while loop.
A square or many other patterns can be print with the help of nested loops.

Assignment:
Based on the logic that we have seen in this video. You have to build a cold to print some patterns.
1 A $$$$
12 AB $ $
123 ABC $ $
1234 $$$$
12345
123456
You can use ASCII values to print the alphabet.
You can also check the video to upload the assignment on the GitHub.
