2.       2.There is one midterm exam and one final exam, each graded on the basis of 100 point (0-100), a float data types

3.       3.The final exam countes for 50% of the final grade, the midterm exam counts for 25% and the two quizzes together count for total of 25%

(Normalize the quiz scores they should be converted to a [percentage before they are average in)

Use the usual grading scale that we have used throughout the semester for assigning letter grades. The program will read in the student scores ( total 4scores) from a text file (ln.txt) and output the students records describe below. The results will be written to a file called (out.txt)

ln.txt

Franks    10   9       96.0    88.5

Jones     8    9       88.5    83.0

Merrill   8    7       66.0    69.5

Smith     9    10      95.2    93.6

Wilson    7    8       76.0    74.5

using namespace std;
int main()
{int quiz1,quiz2;
float midterm,final,grade;
char letter;
string name;
ifstream in;
ofstream out;
in.open("in.txt");       
if(in.fail())           
   { cout<<"input file did not open please check it ";
   system("pause");
   return 1;
   }
out.open("out.txt");
out<<"name Quiz 1 Quiz 2 midterm final Grade Letter ";       
in>>name;
while(in)
{in>>quiz1>>quiz2>>midterm>>final;
   grade=(quiz1/10.*100.+quiz2/10.*100.)/2.*.25+midterm*.25+final*.5;
   if(grade>=90)
        letter='A';
   else if(grade>=80)
        letter='B';
   else if(grade>=70)
        letter='C';
   else if(grade>=60)
        letter='D';
   else
        letter='F';
   out<<name<<" "<<quiz1<<" "<<quiz2<<" "<<midterm<<" "<<final<<" "
       <<grade<<" "<<letter<<endl;
