Control reaches end of non-void function [-werror=return-type]error? How do I fix this? I've included my code below.

Fantastic news! We've Found the answer you've been seeking!

Question:

Control reaches end of non-void function [-werror=return-type]error? How do I fix this? I've included my code below. C++ code bythe way.

#include

#include "GroceryItem.hpp"

namespace

{

constexpr auto EPSILON = 1.0E-4;

}

GroceryItem::GroceryItem( const std::string &productName,

const std::string & brandName,

const std::string & upcCode,

double price )

: _upcCode (upcCode ),

_brandName (brandName ),

_productName (productName),

_price (price )

{}

std::string GroceryItem::upcCode() const

{ return _upcCode; }

std::string GroceryItem::brandName() const

{ return _brandName; }

std::string GroceryItem::productName() const

{ return _productName; }

double GroceryItem::price() const

{ return _price; }

void GroceryItem::upcCode( const std::string & upcCode )

{ _upcCode = upcCode; }

void GroceryItem::brandName( const std::string & brandName)

{ _brandName = brandName; }

void GroceryItem::productName( const std::string &productName )

{ _productName = productName; }

void GroceryItem::price( double price )

{ _price = price; }

std::istream & operator>>( std::istream & stream,GroceryItem & groceryItem )

{

GroceryItem workingItem;

char delimiter = ',';

stream >> std::quoted(workingItem._upcCode) >>delimiter

>> std::quoted(workingItem._brandName ) >>delimiter

>> std::quoted(workingItem._productName) >>delimiter

>> workingItem._price;

if(stream) groceryItem = std::move( workingItem );

return stream;

}

std::ostream & operator<<( std::ostream & stream,const GroceryItem & groceryItem )

{

const std::string delimiter = ", ";

stream << std::quoted( groceryItem.upcCode() ) <

<< std::quoted( groceryItem.brandName() ) <

<< std::quoted( groceryItem.productName() ) <

<< groceryItem.price();

return stream;

}

bool operator==( const GroceryItem & lhs, const GroceryItem& rhs )

{

if constexpr( (false) )

{

return !( lhs < rhs ) && !( rhs < lhs );

}

else

{

return lhs._upcCode == rhs._upcCode

&& lhs._brandName == rhs._brandName

&& lhs._productName == rhs._productName

&& std::abs(lhs._price - rhs._price) < EPSILON;

}

bool operator< ( const GroceryItem & lhs, constGroceryItem & rhs )

{

if( auto result = lhs._upcCode .compare( rhs._upcCode ); result!= 0)

if( auto result = lhs._brandName .compare( rhs._brandName );result != 0)

if( auto result = lhs._productName.compare( rhs._productName);result != 0)

if( std::abs( lhs._price - rhs._price ) >= EPSILON )

return false;

}

bool operator!=( const GroceryItem & lhs, const GroceryItem& rhs ) { return !( lhs == rhs ); }

bool operator<=( const GroceryItem & lhs, constGroceryItem & rhs ) { return !( rhs < lhs ); }

bool operator> ( const GroceryItem & lhs, constGroceryItem & rhs ) { return ( rhs < lhs ); }

bool operator>=( const GroceryItem & lhs, constGroceryItem & rhs ) { return !( lhs < rhs ); }

Sorry for not being entirely clear. I have recieved the error"control reaches end of non-void function [-Werror=return-type]"having to do within the fuction 'bool operator<(constGroceryItem&' . This is being compiled inside of a terminal.How can I fix this error? I've also included another picture alongwith my entire code above.

Once again, I apologize for not being clear. Below I have copyand pasted the code for the file GroceryItem.hpp

#pragma once // include guard

#include #include
