5. Stacks with templates #

Created Wednesday 22 January 2020

Changes required in Stack class:

1. int* data to T* data
2. In push
3. In pop, replace INT_MIN, change it to 0 for the time being.
4. In top, replace INT_MIN by zero, coz it is universal.

No changes in:

1. nextIndex and capacity are always integers.

From now on, we are well equipped with templates as well. We will use it as we want. This is important as Data structures work for any data type, i.e they are data type independent. So templates are very important. This encourages **reuse **over duplication!!
