Nested loops

Nested loops

• Nested loops are common in programming to solve a variety of problems.

• They are an essential part of programming, allowing you to deal with complex repetition structures.

Example to find the factors of numbers from 2 to 100:

Output:
Factors of 2:
Factors of 3:
Factors of 4: 2
Factors of 5:
Factors of 6: 2 3
Factors of 7:
Factors of 8: 2 4
Factors of 9: 3
Factors of 10: 2 5
Factors of 11:
Factors of 12: 2 3 4 6
Factors of 13:
Factors of 14: 2 7
Factors of 15: 3 5
Factors of 16: 2 4 8
Factors of 17:
Factors of 18: 2 3 6 9
Factors of 19:
Factors of 20: 2 4 5 10

• The inner loop successively tests all numbers from 2 to i, displaying those whose division by i is exact.
