You gave the answer in your question
Drinking and driving is not recommended. You need your, hands, feet, brain, and eyes to maneuver around. Drivers must be alert and able to make judgments quickly. Drinking and driving can affect the driver in the following ways.
Judgment
The brain is the first part of the body that is affected by alcohol. Your ability to think clearly and plan ahead levels down to as low as .02%
Concentration
Alcohol can leave you concentrating on only one action. You need to stay focused on several things at once. Alcohol will interrupt your focus and might result to an accident. Many accidents are as a result of a short attention span or a distracted driver.
Vision
Alcohol, especially when taken in excess, will impair your eye movement. Not only will it slow down your eye muscle function but will also reduce peripheral vision.
Answer: A user authentication
Answer:
Here is the script:
function dd = functionDMS(dd)
prompt= 'Enter angle in DD form ';
dd = input(prompt)
while (~checknum(dd))
if ~checknum(dd)
error('Enter valid input ');
end
dd = input(prompt)
end
degrees = int(dd)
minutes = int(dd - degrees)
seconds = ( dd - degrees - minutes / 60 ) * 3600
print degrees
print minutes
print seconds
print dd
Explanation:
The script prompts the user to enter an angle in decimal degree (DD) form. Next it stores that input in dd. The while loop condition checks that input is in valid form. If the input is not valid then it displays the message: Enter valid input. If the input is valid then the program converts the input dd into degrees, minutes and seconds form. In order to compute degrees the whole number part of input value dd is used. In order to compute the minutes, the value of degrees is subtracted from value of dd. The other way is to multiply remaining decimal by 60 and then use whole number part of the answer as minutes. In order to compute seconds subtract dd , degrees and minutes values and divide the answer by 60 and multiply the entire result with 3600. At the end the values of degrees minutes and seconds are printed. In MATLAB there is also a function used to convert decimal degrees to degrees minutes and seconds representation. This function is degrees2dms.
Another method to convert dd into dms is:
data = "Enter value of dd"
dd = input(data)
degrees = fix(dd);
minutes = dd - degrees;
seconds = (dd-degrees-minutes/60) *3600;
