Question

Today we are practicing our ABC's. Write a program that will accept three separate names as inputs (ex: "billy"). Then display the names in alphabetical order. The names will always use all lowercase letters. For example: given the input

"lauren" 
"rodger"
"bob"

The output should be

"bob"
"lauren"
"rodger"

Note: Think carefully about the logic needed to solve this problem and remember there are only three names that need to be sorted.

P.S. The computer language we are using is C++

Answer 1

#include <iostream>
using namespace std;

int main()
{
string str[3], temp;

cout << "Enter 3 strings : " << endl;

for(int i = 0; i < 3; i++) // taking input from user
cin >> str[i];

for(int i = 0; i < 2; i++) // sorting the strings in alphabetical order
for( int j = i+1; j < 3; j++)
{
if(str[i] > str[j]) // comparing two strings
{
temp = str[i];
str[i] = str[j];
str[j] = temp;
}
}

cout << endl << "Names in alphabetical order : " << endl;

for(int i = 0; i < 3; i++) // displaying sorted strings
cout << str[i] << endl;

return 0;
}

Output :
