In this program, we calculate the grade and percentage of a student according to 6 subjects marks by the given below methods by if-else loop concepts basic to advance loop in c++
best if else if loop example with explanation
The method of assigning grades is –
percentage>=85 grade=A
percentage<85 and percentage>=70 grade=B
percentage<70 and percentage>=55 grade=C
percentage<55 and percentage>=40 grade=D
percentage<40 grade=E
using namespace std;
int main()
{
float m1,m2,m3,m4,m5,m6,total,per;
//Makeing all marks Float type variables
char grade;
//Makeing a char type for grade
cout <<“Please enter S1 marks of Subject 1 :”<
cout<<“Please enter S1 marks of Subject 2 :\t ” <
cout<<“Please enter S1 marks of Subject 3 :\t “<< endl;
cin>>m3;
cout<<“Please enter S1 marks of Subject 4 :\t “<< endl;
cin>>m4;
cout<<“Please enter S1 marks of Subject 5 :\t “<< endl;
cin>>m5;
cout<<“Please enter S1 marks of Subject 6 :\t “<< endl;
cin>>m6;
//Calculate the percentage of all Marks
total=m1+m2+m3+m4+m5+m6;
per=total/6;
//Condtion Check for to find the grade of
if(per>33){
if(per>=85){
grade=’A’;
}
else if(per>=70){
grade=’B’;
}
else if(per>=55){
grade=’C’;
}
else if(per>=40){
grade=’D’;
}
else {
grade=’E’;
}
cout<<“Student S1 passed with ” << grade << ” Grade with ” <
else{
cout<<“Students S1 is Fail in the Examnation”<
return 0;
}
Suppose Student S1 find the folloing marks:
Subject 1=71, Subject 2 =72, Subject 3 = 73,
Subject 4 = 74, Subject 5 = 75, Subject 6 = 76,
output:
71
Please enter S1 marks of Subject 2 :
72
Please enter S1 marks of Subject 3 :
73
Please enter S1 marks of Subject 4 :
74
Please enter S1 marks of Subject 5 :
75
Please enter S1 marks of Subject 6 :
76
Student S1 passed with B Grade with 73.5Process returned 0 (0x0) execution time : 14.507 s
