SIMPLE CLASS DESIGN IN C++, NAMESPACES, OBJECTS CREATIONS EXNO: 1 AIM: To write a C++ program to maintain student detail and compute the grade using class concept. ALGORITHM: Step1: Start the program Step2: Define a class student with the data members name, roll, marks, total, average, Grade . Step3: Declare the member functions getdata, totalmark, avg, grade and printdata. Step4: The function getdata is used to accept name, roll and subject marks. Step5: The function totalmark is used to calculate the total by adding the marks. Step6: The function avg is used to calculate the average by dividing the total mark by no Of subjects. Step7: The function grade is used to compute the grade based on the average marks. Step8: The function printdata is used to display the name, roll, total, average, grade. Step9: In the main function declare an object for the class student and call the member Function one by one. Step10: Stop the program PROGRAM: #include #include using namespace std; class student { string name; int i; int roll; int m[6]; int total; int avg; char grade; public: void getdata(); void totalmar(); void avg1(); void grade1(); void display(); 3 STUDENTS RESULT PROCESSING

}; void student::getdata() { coutname; coutroll; cout80) grade='B'; else if(avg>70) grade='C'; else if(avg>60) grade='D'; else if(avg>50) grade='E'; else grade='F'; } void student :: display() { cout
