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
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
#include<conio.h>
void main()
{
float m1,m2,m3,m4,m5,m6,total,per;
//Makeing all marks Float type variables
char grade;
//Makeing a char type for grade
printf(“Please enter S1 marks of Subject 1 :\t “);
scanf(“\t%f\t”,&m1);
printf(“Please enter S1 marks of Subject 2 :\t “);
scanf(“\t%f\t”,&m2);
printf(“Please enter S1 marks of Subject 3 :\t “);
scanf(“\t%f\t”,&m3);
printf(“Please enter S1 marks of Subject 4 :\t “);
scanf(“\t%f\t”,&m4);
printf(“Please enter S1 marks of Subject 5 :\t”);
scanf(“\t%f\t”,&m5);
printf(“Please enter S1 marks of Subject 6 :\t “);
scanf(“\t%f\t”,&m6);
printf(“\n”);
//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’;
}
printf(“Student S1 passed with %c Grade with %.ff\n”,grade,per);
}
else{
printf(“Students S1 is Fail in the Examnation”);
}
getch();
}
Suppose Student S1 find the following marks
Subject 1=81, Subject 2 =83, Subject 3 = 78, Subject 4 = 90, Subject 5 = 68, Subject 6 = 87,
Please enter S1 marks of Subject 1: 81
Please enter S1 marks of Subject 2: 83
Please enter S1 marks of Subject 3: 78
Please enter S1 marks of Subject 4: 90
Please enter S1 marks of Subject 5: 68
Please enter S1 marks of Subject 6: 87Student S1 passed with B Grade with 78.500000Process returned 1 (0x1) execution time : 25.400 s
