C++ assignment - Calculating the distance between latitudes and longitudes The following is an example of the program's execution, as it should appear in the shell. Boldfaced, italicized text indicates input, while normal text indicates ouptut.
33.9425/N 118.4081/W Los Angeles International Airport

20.8987/N 156.4305/W Kahului Airport
47.4647/N 8.5492/E Zurich Airport
23.4356/S 46.4731/W Sao Paolo-Guarulhos International Airport
Start Location: 33.9425/N 118.408/W (Los Angeles International Airport)
Closest Location: 20.8987/N 156.43/W (Kahului Airport) (2483.3 miles)
Farthest Location: 23.4356/S 46.4731/W (Sao Paolo-Guarulhos International Airport) (6164.9 miles)
Formula:
let lat1 be the latitude of the first location
let lat2 be the latitude of the second location
let lon1 be the longitude of the first location
let lon2 be the longitude of the second location
let dlat be the difference in latitudes between the locations
let dlon be the difference in longitudes between the locations
let a = sin2(dlat/2) + cos(lat1) * cos(lat2) * sin2(dlon/2)
let c = 2 * atan2(sqrt(a), sqrt(1 - a))
let d = R * c R, in this part of the formula, is the radius of the Earth R = 3,959.9 miles

Formatting rows and columns is similar to cell formatting. in an openoffice calc spreadsheet, you can format data entered into rows and columns with the of the rows and columns options. you can insert rows and columns into, or delete rows and columns from, a spreadsheet. use the insert or delete rows and columns option on the insert tab. alternatively, select the row or column where you want new rows or columns to appear, right-click, and select insert only row or only column options. you can hide or show rows and columns in a spreadsheet. use the hide or show option on the format tab. for example, to hide a row, first select the row, then choose the insert tab, then select the row option, and then select hide. alternatively, you can select the row or columns, right-click, and select the hide or show option. you can adjust the height of rows and width of columns. select row and then select the height option on the format tab. similarly, select column, then select the width option on the format tab. alternatively, you can hold the mouse on the row and column divider, and drag the double arrow to the position. you can also use the autofit option on the table tab to resize rows and columns.
