A fi le named temp.dat contains information collected from a set of thermocouples. The data in the fi le are shown in Table 8.8 . The fi rst column consists of time measurements (one for each hour of the day), and the remaining columns correspond to temperature measurements at different points in a
process.
(a) Write a program that prints the index numbers (rows and columns) of temperature data values greater than 85.0. ( Hint : You'll need to use the fi nd command.)
(b) Find the index numbers (rows and columns) of temperature data values less than 65.0.
(c) Find the maximum temperature in the file and the corresponding hour value and thermocouple number.
