Question

Prompt the user to enter two character strings. The program will then create a new string which has the string that appears second, alphabetically, appended to the end of the string that shows up first alphabetically. Use a dash (-') to separate the two strings. You must implement the function string appendStrings(string, string), where the return value is the combined string. Display the newly created string. Your program must be able to handle both uppercase and lowercase characters. You are allowed to convert all the input characters to lowercase Example: If "dog" and "bird" have been entered then "bird-dog" is returned then displayed. Sample code for string case conversion ? i++) < mystring, size(); - tolower(mystring[i]); for i # 0; (int mystring[i]

Answer 1

#include<iostream>
#include<string>
#include<ctype.h>

using namespace std;

string appendString(string a, string b){

   string str1 = a;
   string str2 = b;
   string str = "";

   //str = str + (char)tolower(a[0]);
  
   for (int i = 0; i<a.size(); i++){
       str1 = str1 + (char)tolower(a[i]);
   }
   for (int i = 0; i<b.size(); i++){
       str2 = str2 + (char)tolower(b[i]);
   }
   if (str1 >=str2){
      str = b + "-" + a;
   }
   else {
      str = a + "-" + b;
   }
  
   return str;
}

int main(){

   cout << appendString("dog","bird") << endl;
   return 0;
}
