You want to conduct a survey within your classroom, on the quality of canteen's food. You ask each of your class fellows to rank the quality of food between 1 and 5 (1 representing excellent quality and 5 representing worst quality). During the survey, you make a list containing the roll# of student and the opinion given by that student. The list can be as follow Roll # Opinion 234 1 235 1 236 5 237 1 238 2 239 3 240 5 241 5 242 1 To get the results of the survey, you need to get the frequency of each opinion. The frequency of an opinion is determined by counting the number of students giving that opinion. For example, for the above list the frequency of value 1 is 4 and frequency of value 4 is 0. After getting the frequency of each opinion/rank, you can easily judge about the quality of the food by seeing through the frequency of each rank. You need to develop a program to calculate the results of this survey. The program inputs the opinion of 50 students and counts the frequency of each opinion. It then displays a report showing the frequency of each opinion. Following is an incomplete program. Complete the program by writing the missing code and test it. void main() { int quality; cout<<"Enter a number between 1 to 5 to rank the quality of food"; cout<> quality; /*Complete the program to frequency of each value and display the result of survey*/ if(quality == 1) cout<<"Canteen's food is excellent "; else if (quality == 2) cout<<"Canteen's food is good "; else if (quality == 3) cout<<"Canteen's food is normal "; else if (quality == 4) cout<<"Canteen's food is bad ";
