MainOperations

Project is divided into three parts disk, logical and mathematical operations. The programs is built well to handle all the invalid input by the user by giving them an option to re-prompt or exit. Disk operations include word filtering (filters out unnecessary expressions from the text/file provided). Logical operation allows one to compare strings, character or number (thus creating histogram/ finding mean, median, mode, largest or smallest). Mathematical operations include advance calculator that can be used to preform series/multiple calculations on previous result. Advance operations include finding remainder, sine, cosine, tangent or Logarithms of the expression.
