What is jagged array
A jagged array is an array of arrays.

Let us understand jagged array with an example.
1. There are 3 employees – Mark, Matt, John
2. Mark has a bachelor, master and doctrate degree (3 qualifications)
3. Matt has only a bachelor degree (1 qualification)
4. John has a bachelor and a master degree (2 qualifications)

Different employees have different number of qualifications. To store their qualifications in a data structure, Jagged array is one of the choices.

In this example, we have created an array of string arrays. In a similar way, we create an array of integer arrays, an array of decimal arrays etc.
