Else without previous if

[HelenI]

I'm trying to find the average and it says that p must not be g>=5 or g<=5
and i get the error ...... else without a previous if...please help

#include<iostream>
#include<iomanip>
using namespace std;
int main()
{
float p,g,m;
cin>>p>>g;
if
((p==g+3)||(p==g-3))
m=(((p)+g)/2);
cout<<fixed<<setprecision(2)<<m<<endl;

else {

if
((p>=g+5)||(p<=g+5))
p=(p==g+3)||(p==g-3);
m=(((p)+g)/2);
cout<<fixed<<setprecision(2)<<m<<endl;

}

Use a bracket after your condition to execute some statement inside if

if(condition){
  //block of statement
}else{
  //block of statement
}

What were you doing here is

if(condition)
  cout<<"test";//if will end here
  cout<<"test2";//its not a part of if
else{ //so else here is declare after if is ended
  //block of statement
}

I formatted your code and coimmented it:

#include<iostream>
#include<iomanip>
using namespace std;
int main()
{
    float p,g,m;
    cin>>p>>g;
    if ((p==g+3)||(p==g-3))
        m=(((p)+g)/2); //This statement belongs to if block
    cout<<fixed<<setprecision(2)<<m<<endl; //This is not
    //If block is already ended and next exle does not have a corresponding if
    else {
        if ((p>=g+5)||(p<=g+5))
            p=(p==g+3)||(p==g-3);
        m=(((p)+g)/2);
        cout<<fixed<<setprecision(2)<<m<<endl;
    }

Use braces to join multiline block together.

Exactly as @lendraDwi said and also p=(p==g+3)||(p==g-3)
Doesn't do what you might be intending because it assigns p a bool value 0 if both statements
Are false or 1 if either or both statements are true.
