If you are using the String class to store your names then you can use the < or > operators to compare the order, alphabetically, they appear in.

String names[3];
int numberOfNames = 3;
names[0] = "abc";
names[1] = "dfg";
names[2] = "hij";

printf("before %s%s%s\n", names[0],names[1],names[2]);
for( int i = 0; i < numberOfNames-1; i++ )
{
for( int j = 0; j < numberOfNames; j++ )
{
if( names[j] < names[j+1] )
{
names[j].swap( names[j+1] );
}
}
}

printf("after%s%s%s\n", names[0],names[1],names[2]);


output:
before abcdfghij
after hijdfgabc

Question 1: 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 determine the frequency of each opinion value. 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 opinion value 1 is 4 and frequency of opinion value 4 is 0. After getting the frequency of each opinion, you can easily judge about the quality of the food by seeing through the frequency of each opinion. 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. Sample output: Opinion Frequency Remarks 1 5 Excellent 2 10 Good 3 15 Normal 4 10 Bad 5 10 Really bad
