In this post, we will write a** C++ program to calculate the result of students using marks**. user will enter the marks of his subject and the program will print the total marks obtained by the student, average of total marks, and grade.

## C++ program to calculate results of students

#include<iostream> #include<conio.h> int main(void) { int comp, phy,math,eng,stat,total; float avg; std::cout<<"Enter the marks of computer = "; std::cin>>comp; std::cout<<"Enter the marks of physics = "; std::cin>>phy; std::cout<<"Enter the marks of mathematics = "; std::cin>>math; std::cout<<"Enter the marks of english = "; std::cin>>eng; std::cout<<"Enter the marks of statistics = "; std::cin>>stat; total = (comp+phy+math+eng+stat); avg = ((total/500.0)*100.0); std::cout<<"The total marks obtained by student = "<<total <<std::endl; std::cout<<"The average of total marks is = "<<avg<<std::endl; if(avg >= 85) std::cout<<"The grade is A+"; if(avg >= 75 && avg <= 84) std::cout<<"The grade is A"; if(avg >= 60 && avg <= 74) std::cout<<"The grade is B"; if(avg >= 50 && avg <= 59) std::cout<<"The grade is C"; if(avg < 50) std::cout<<"Fail"; return 0; }

### Output

Enter the marks of computer = 67 Enter the marks of physics = 64 Enter the marks of mathematics = 75 Enter the marks of english = 80 Enter the marks of statistics = 82 The total marks obtained by student = 368 The average of total marks is = 73.599998 The grade is B
