C$++$ Classes and vectors$/$classes$.$ The program first reads integer purchaseCount from input, representing the number of pairs of inputs to be read. Each pair has a string and a character, representing the purchase's food and option, respectively. One Purchase object is created for each pair and added to vector purchaseList.If a Purchase object's option is equal to $\text{'}$B$\text{'},$ call the Purchase object's Print$()$ function.

Example: If the input is: $3$

egg B bamboo A corn B

then the output is:

Purchase: egg, Option: B

Purchase: corn, Option: B
