Write a C program that will: ask the user for the name of the data file open the data file if the file fails to open, print an error message and repeat step 1 Skip the first line of the data file While: read three points Use a function to calculate the length of each side of the triangle Use a second function to calculate the area of the triangle Print the three vertices for each triangle Print the area of each triangle After all points have been read. Report The maximum area The minimum area The average area Note: Round all output to two decimal places.

Matlab question: use switch and anythe lottery game matches three different integer numbers between 1 and 10. winning depends on how many matching numbers are provided by a player. the player provides three different integers between 1 and 10.if there is a match of all 3 numbers, the winning $ 1000.if there is a match with 2 numbers, the winning $ 10.if there is a match of all with 1 numbers, the winning $ 1.with no match, the winning is $0.write a function lottery3 that checks three numbers provided by a player and determine the winning amount. if the user mistakenly enters same number twice/thrice and if that number matches one of the winning numbers, the code should count that number only once and display correct result. the player doesn’t have to guess the order of numbers. the input to the function lottery3 can have up to two input arguments. the first input argument is a row array numbers with 3 numbers. if the second argument input testcode is present, and is a row vector of 3 values, the function lottery3 uses the code in testcode as the three winning numbers (the test must be three different integer numbers between 1 and 10), else three different numbers will be automatically generated by testcode. the ouput should return the variable winnings and the three winning numbers in the row array winnumbers. hint: make use of the internal function any. restriction: the function must use switch-case statements to determine the winning. example #1: winning = lottery3( [1,2,1],[1,2,3])produceswinning =10example #2: [winning, winnumbers] = lottery3( [1,2,3])produceswinning =3winnumbers =8 5 3
