C Program to Evaluate the Result of a Student

mark1, mark2 and mark3 are the inputs from the user which corresponds to the marks scored in each subject. Then the total and average marks are calculated and final result is displayed. If the average is greater than 60 then first class result is displayed.

Program:

 #include<stdio.h>
 int main()
 {
   int mark1, mark2, mark3, total;
   float avg;

   printf("Enter marks of three subjects: ");
   scanf("%d %d %d",&mark1, &mark2, &mark3);

   if(mark1>=35 && mark2>=35 && mark3>=35)
   {
     total = mark1 + mark2 + mark3;
     avg = total/3;

     printf("Total marks scored = %d\n",total);
     printf("Average mark = %.1f\n", avg);

     if(avg>=60)
     {
       printf("first class.");
     }
     else
     {
       printf("second class.");
     }
   }
   else
   {
     printf("fail");
   }

   return 0;
 }

Output:

Enter marks of three subjects: 60 70 80
Total marks scored = 210
Average mark = 70.0
first class.
