Now, modify the version of the greenvillerevenue program created in chapter 5 so that after the user enters the number of contestants in this year’s competition, the user is prompted for the appropriate number of contestant names and a code for each contestant that indicates the type of talent: s for singing d for dancing m for playing a musical instrument o for other. make sure that all entered codes are valid, and if not, reprompt the user to enter a correct code. for example, if y is input, output y is not a valid code, and reprompt the user until a valid code is entered. after contestant data entry is complete, display a count of each type of talent. for example, if there were ten singers, four dancers, 7 people who play musical instruments, and 1 in the other category, the output should be: contestants with talent musical instrument are: michellenick using system; using static system. console; class greenvillerevenue{ static void main() { const int entrance_fee = 25; const int min_contestants = 0; const int max_contestants = 30; string entrystring; int numthisyear; int numlastyear; int revenue; write("enter number of contestants last year > > "); entrystring = readline(); numlastyear = convert. toint32(entrystring); while(numlastyear < min_contestants || numlastyear > max_contestants) { writeline("number must be between {0} and {1}", min_contestants, max_contestants); write("enter number of contestants last year > > "); entrystring = readline(); numlastyear = convert. toint32(entrystring); } write("enter number of contestants this year > > "); entrystring = readline(); numthisyear = convert. toint32(entrystring); while(numthisyear < min_contestants || numthisyear > max_contestants) { writeline("number must be between {0} and {1}", min_contestants, max_contestants); write("enter number of contestants this year > > "); entrystring = readline(); numthisyear = convert. toint32(entrystring); } revenue = numthisyear * entrance_fee; writeline("last year's competition had {0} contestants, and this year's has {1} contestants", numlastyear, numthisyear); writeline("revenue expected this year is {0}", revenue. tostring("c")); if(numthisyear > 2 * numlastyear) writeline("the competition is more than twice as big this year!
