Question

Program asks user for a series of strings (their name and an 8 letter word), prints their name, the first and last three letters of the word, and then prints their word backwards. need help with the for loop to display string backwards.

    #include <iostream> 

int main () { 


string FirstName; 

string LastName; 

string MiddleName; 

string Names; 

string string1; 

int len; 

int x;  

 cout << "Hello. What is your first name?" << endl; 

 cin >> FirstName; 

 cout << FirstName  << ", what is your last name?" << endl; 

 cin >> LastName; 

 cout << "And your middle name?" << endl; 

 cin >> MiddleName; 

 Names = LastName + ", " + FirstName + ", " + MiddleName; 

 cout << Names << endl; 

 cout << "Please enter a word with 8 or more characters (no spaces): " << endl; 

 cin >> string1; 

 len = string1.length(); 

   if (len < 8){
     cout << "Error. Please enter a word with 8 or more characters and no spaces: " <<    endl; 

     cin >> string1; 
 }

  else if (len >= 8){

     cout << "The word you entered has " << string1.length() << " characters."<<endl; 

 cout << "The first three characters are " << string1.substr(0,3) << endl; 

 cout << "The last three characters are " <<string1.substr(string1.length()-3,3) << endl; 

x = string1.length()-1; 

for (x = string1.length()-1; x >=0; x--){
 cout << "Your word backwards: " << string1[x]; 
}
}



return 0; 
} 

Answer 1

You were almost there:

cout << "Your word backwards: ";
for (x = string1.length()-1; x >=0; x--){
   cout << string1[x]; 
}

This way the loop will print each character in string1 but in reverse order, and the text "Your word backwards: " only once.
