system ("pause");

return 0;

}

double get_Score(double b ,double c ,double d ,double e , double f)
{
double score;

score = ( (b / 100) * 30 ) + ( ( c / 100) * 10 ) + ( ( d / 100) * 15 ) + ( ( e / 100) * 25) + ( ( f / 100) * 20);

return score ;
}

void grade()
{

double score;


if ( score >= 0 && score <= 49.9)

else if ( score >= 80 && score <= 100 )
cout << "Grade is" << " " << "A" << endl;

return;

you need to pass into the grade method the score returned by get_Score and get rid of the "double score;" defined within grade method.

i still dont understand..can you show me?

change

void grade()
{

double score;

to this:

void grade(double score)
{

and

score = get_Score(b, c ,d , e ,f ); //function called here 
grade();

to this:

score = get_Score(b, c ,d , e ,f ); //function called here 
grade(score);

you need to pass the score to the grade function, the grade function cant know the score if you dont tell it what the score is

thats what binarybob said
