Answer to Question #241650 in C++ for Princewill Unuigbe

Question

The program should have an array of 12 structures to hold weather data for an entire year. When the program runs, it should ask the user to enter data for each month. The program then should display month-wise min., max. and average temperatures and rainfalls in a table-like format. In addition, it should display average min., average max. and average mean temperature of the entire year. Similarly, it should display average min., average max. and average mean rainfall of the entire year. The following checks should be implemented for valid input. • Temperature range: -70 to +60 C • Rainfall range: 1mm to 25mm • Min. value <= Average value <= Max value
