Question

When I try to run the program it gives me an erron saying Expected expresion on this line,

else if(phrase.find(sub_String)!=std::string::npos).

#include

#include

#include

using namespace std;

  

int main( )

{

  

  

  

// Defining variables.

//Initilizing variables.

int magicNum;

int magicNum1;

int position;

int phraseLenght;

string vowels = "aeiou";

string phrase;

string sub;

  

   // The phrase and the sub phrase

cout << "Enter a phrase:" << endl;

std::getline (std::cin,phrase);

  

cout << "Enter a 3-character sub:" << endl;

cin >> sub;

  

if (sub.length()!=3){

  

{

cout << "Incorrect length of substring" << endl;

  

  

}

else if(phrase.find(sub_String)!=std::string::npos){

  

cout << "Substring occurs " << phase.find(sub) << endl;

  

position = phrase.find(sub)

  

// removes the substring.

  

cout << "Phrase without substring is:" << phrase.replacement(position,3,"") << endl;

  

//finding length of magic string

  

phraselength = phrase.lenght();

  

magicNum = phrase.Length % 5;

  

magicNum1 = phrase.find_first_of(vowels);

  

if (magicNum == 0)

}

if (magicNum1 = 5)

{

  

cout<<"magic string!"<< endl;

}

  

}

else

{

cout<<"Not a magic string";

  

}

return 0;

}
