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
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)

Explanation / Answer
#include<iostream>
#include<string>
using namespace std;
int main( )
{
// Defining variables.
//Initilizing variables.
int magicNum;
int magicNum1;
int position;
int phraselength;
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)!=std::string::npos){
cout << "Substring occurs " << phrase.find(sub) << endl;
position = phrase.find(sub);
// removes the substring.
cout << "Phrase without substring is:" << phrase.replace(position,3,"") << endl;
//finding length of magic string
phraselength = phrase.length();
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;
}
