3) Write a script that will prompt the user for a temperature in degrees Celsius, and then an 'F' for Fahrenheit or 'K' for Kelvin. The script will print the corresponding temperature in the scale specified by the user. For example, the output might look like this: >>Enter the temp in degree C: 29.3 >>Do you want K or F? F. >>The temp in degrees F is 84.7 The format of the output should be exactly as specified above. The conversions are: F =C+32 K = C + 273.15 4) A file called "hightemp.txt" was created some time ago which stores, on every line, a year followed by the high temperature at a specific location for each month of that year. For example, the file might look like this: 89 42 49 55 72 63 68 77 82 76 67 90 45 50 56 5962 68 75 77 75 66 91 44 43 60 60 60 65 69 74 70 70 As can be seen, only two digits were used for the year (which was common in the last century). Write a script that will (1) read this file into a matrix, (2) create a new matrix that stores the years correctly as 19xx, and (3) then write this to a new file called "Year2000.txt. (Hint: add 1900 to the entire first column of the matrix.) Such a file, for example, would look like this: 1989 42 49 55 72 63 68 77 82 76 67 1990 45 50 56 59 62 68 75 77 75 66 1991 44 43 60 60 60 65 69 74 70 70
