I'm trying to solve a balanced parentheses problem, here in my code I'm trying to get 1 from a function is_empty() if top of my stack is empty but then here i am stuck with this ugly error.
int is_Empty()
{
int x=0;
if (top==NULL)
{
x=1;
}
return x;
}
here is how i recive it
if (s1.is_Empty==1)
{
cout<<"matched"<<endl;
}
my error log
bal.cpp:112:20: error: invalid use of member 'int stack::is_Empty()' (did you forget the '&' ?)
if (s1.is_Empty==1)
~~~^~~~~~~~

if (s1.is_Empty==1)
That is not how to call a function.
Here:
if (s1.is_Empty()==1)

and this is the error
basic list.cpp:26:12: error: expected initializer before '->' token

can someone help me out!
You have declared your variable at
cell *n=new cell;
at the next line you are trying to re-declare it
cell *n->data=first;
Replace it with:
n->data=first;

Why is g++ giving an error like this?
blahblah.h:80:10: error: decomposition declaration not permitted in this context
float[NUM_OUTPUTS] output_buffer;
(Already solved, but creating this because there's no good google hits for this error text, and the error message is inscrutable.)
In C++ declarations, the array size goes after the variable name, not after the type:
float output_buffer[NUM_OUTPUTS];

So I'm creating this function as part of a larger program for my C++ course, and I am getting this error: no match for 'operator<<' followed by a bunch of gibberish whenever the compiler goes through this function
void print24hour(Time& start)
{
cout<<"The lecture starts at: ";
cout<<setfill('0')<<setw(2)<< start.getHours <<":"<<setfill('0')<<setw(2)<<start.getMinutes<<":"<<setfill('0')<<setw(2)<<start.getSeconds;
}
void print24hour(Time& end)
{
cout<<" and ends at: ";
cout<<setfill('0')<<setw(2)<<end.getHours<<":"<<setfill('0')<<setw(2)<<end.getMinutes<<":"<<setfill('0')<<setw(2)<<end.getSeconds<<endl;
}
Any solutions to my problem would be greatly appreciated
To get a function's return value you need to call it. Do this by appending parantheses to the member functions like end.getMinutes().

// m_values is of type std::vector<std::pair<std::string,INIValue> >
std::find_if(this->m_values.begin(),this->m_values.end, [name](std::pair<std::string,INIValue> v)->bool { return v.first == name;});
Below is the error:
error: no matching function for call to ‘find_if(std::vector<std::pair<std::basic_string<char>, INIValue> >::iterator, <unresolved overloaded function type>, INISection::value(const string&)::__lambda0)’
what am I missing?
You forgot braces for the second parameter.
this->m_values.end()
Also you might want to adjust your lambda a little bit. You search for a value, no need to copy each one of the vector.
[&name](const std::pair<std::string, INIValue> &v)->bool { return v.first == name;}

I have a function
int Customer::myFunction(char * cPhoneNumber)
{
//Something here
}
And i am trying to call this function with a parameter like:
char cPhoneNumber[MAX_STRING_LENGTH]; //MAX_STRING_LENGTH = 256
memset(cPhoneNumber, 0, sizeof(cPhoneNumber));
//Some value assigned
myFunction(cPhoneNumber);
But i get this error here:
cannot convert parameter 1 from 'char [256]' to 'char'
Why am i unable to pass this, please help.
The error is telling you that the declaration of Customer::myFunction is actually:
Customer::myFunction(char cPhoneNumber); // note char, not char*
You showed us the definition, but not the declaration. Either that, or you didn't post your definition correctly.
