Error Message

Hi guys,
I am trying to help my friend, he is using V C++.
The problem that we are having is this error message:

Code:

#include <iostream.h>

float v1,v2,v3,v4,v5;

void getValues()
{

	cout<<" Please enter the first Value: " ;
	cin>> v1;

	cout<<" Please enter the secod Value: " ;
	cin>> v2;

	cout<<" Please enter the Third Value: " ;
	cin>> v3;

	cout<<" Please enter the Fourth Value: " ;
	cin>> v4;

	cout<<" Please enter the Fifth Value: " ;
	cin>> v5;

}


float CalcAvarage (float v01, float v02,  float v03, float v04, float v05)
{

	float ave;

	float scores[5];
	scores[0]= v01;
	scores[1]= v02;
	scores[2]= v03;
	scores[3]= v04;
	scores[4]= v05;
	
	float temp;
	for (int i=0; i<5; i++)
		for ( int j= i+1; j<5; j++)
			if( scores[i] <= scores[j]){
				temp = scores[i]; 
				scores[i]= scores[j]; 
				scores[j] = temp;
			}// end if
	for ( i=0; i<5; i++){
		cout<<" Arrange the scores like " << i<< "  is : "<< scores[i];
	}
	cout<<endl<<endl;;

	for(  i=0; i<4; i++){
	 ave += scores[i];  
	}
	ave = ave /4;
	
return ave;
}


float findLowest ()
{

	float lowest;
	
	lowest= v1;
	if (lowest <= v2)
		lowest =  v2;
	if (lowest <= v3)
		lowest =  v3;
	if (lowest <= v4)
		lowest =  v4;
	if (lowest <= v5)
		lowest =  v5;


return lowest;
}



int main()
{

	float ave0;
	float lowest;
	
	getValues();
	lowest = findLowest();

	
	ave0 = CalcAvarage(v1, v2, v3, v4, v5);

return 0;
}

Here is the error message :

Fatal error C1010: unexpected end of file while looking for precompiled header directive
Error executing cl.exe.

update, there is no error message, but the program crash.

p2.dll - 1 error(s), 0 warning(s)

Its telling you that it cant find iostream.h, so lets try it without the h and with namespace.

try this code:

Code:

#include <iostream>

using namespace std;

float v1,v2,v3,v4,v5;

void getValues()
{

	cout<<" Please enter the first Value: " ;
	cin>> v1;

	cout<<" Please enter the secod Value: " ;
	cin>> v2;

	cout<<" Please enter the Third Value: " ;
	cin>> v3;

	cout<<" Please enter the Fourth Value: " ;
	cin>> v4;

	cout<<" Please enter the Fifth Value: " ;
	cin>> v5;

}


float CalcAvarage (float v01, float v02,  float v03, float v04, float v05)
{

	float ave;

	float scores[5];
	scores[0]= v01;
	scores[1]= v02;
	scores[2]= v03;
	scores[3]= v04;
	scores[4]= v05;
	
	float temp;
	for (int i=0; i<5; i++)
		for ( int j= i+1; j<5; j++)
			if( scores[i] <= scores[j]){
				temp = scores[i]; 
				scores[i]= scores[j]; 
				scores[j] = temp;
			}// end if
	for ( i=0; i<5; i++){
		cout<<" Arrange the scores like " << i<< "  is : "<< scores[i];
	}
	cout<<endl<<endl;;

	for(  i=0; i<4; i++){
	 ave += scores[i];  
	}
	ave = ave /4;
	
return ave;
}


float findLowest ()
{

	float lowest;
	
	lowest= v1;
	if (lowest <= v2)
		lowest =  v2;
	if (lowest <= v3)
		lowest =  v3;
	if (lowest <= v4)
		lowest =  v4;
	if (lowest <= v5)
		lowest =  v5;


return lowest;
}



int main()
{

	float ave0;
	float lowest;
	
	getValues();
	lowest = findLowest();

	
	ave0 = CalcAvarage(v1, v2, v3, v4, v5);

return 0;
}

Precompiled headers are a nice feature where it compiles all your common header files only ONCE so that compile times are smaller. Just add this into your stdafx.h file:

Code:

#include <iostream>
using namespace std;

... and in every single file you have in your project, make sure it includes "stdafx.h" Put all your common includes in there and you don't have to include them again in your seperate files.

You can turn this feature off by browsing though options or making a new project without precompiled headers (empty project).

I came back to post the program after I fix it, and I find the same solution.

Thank you for your help.

Code:

#include <iostream.h>
#include <math.h>

float v1,v2,v3,v4,v5;

void getValues()
{

	cout<<" Please enter the first Value: " ;
	cin>> v1;

	cout<<" Please enter the secod Value: " ;
	cin>> v2;

	cout<<" Please enter the Third Value: " ;
	cin>> v3;

	cout<<" Please enter the Fourth Value: " ;
	cin>> v4;

	cout<<" Please enter the Fifth Value: " ;
	cin>> v5;

}


float CalcAvarage (float v01, float v02,  float v03, float v04, float v05)
{

	float ave;
	float total= 0;
	float scores[5];
	float temp;

	scores[0]= v01;
	scores[1]= v02;
	scores[2]= v03;
	scores[3]= v04;
	scores[4]= v05;
	
	for (int i=0; i<5; i++)
		for ( int j= i+1; j<5; j++)
			if( scores[i] <= scores[j]){
				temp = scores[i]; 
				scores[i]= scores[j]; 
				scores[j] = temp;
			}// end if

	
	for(int k =0; k<4; k++)
	 total = total + scores[k];  
	
    cout<< "total points = "<<total ;
	ave = total / 4;


return ave ;
}


float findLowest ()
{

	float lowest;
	
	lowest= v1;
	if (lowest >= v2)
		lowest =  v2;
	if (lowest >= v3)
		lowest =  v3;
	if (lowest >= v4)
		lowest  = v4;
	if (lowest >= v5)
		lowest =  v5;
return lowest;
}

int main()
{

	float ave0;
	float lowest;
	
	getValues();

	lowest = findLowest();
	cout<<endl<<endl;
	cout<<" The lowest score is :"<< lowest<<" Points" <<endl;
	
	ave0 = CalcAvarage(v1, v2, v3, v4, v5);
	cout<<" The avarage of the four highest Four scores is:" << ave0<<" Points"<< endl;
	
	int x;
	cin>>x;
return 0;
}

But what is about the using namespace std;
why I should use it with this program?

Thank you about the information about name spacing.

I am ganna close this thread now.

Go on then, close it..hehe
