The program that was written below to be used for keeping track of textbooks required and recommended for classes and the cost of those textbooks( Heres the link in Chegg for the formats the instruction wanted: "https://www.chegg.com/homework-help/questions-and-answers/write-program-c-used-keeping-track-textbooks-required-recommended-classes-cost-textbooks-p-q21146933" ) , the code keeps throwing out of range error for "case: C" when trying to run input test.txt file. Which when it parsing the C it errors out. Can anyone take a look at the code and see what can be causing such error for "case: C" in the code when giving this whole test inputs below:
