Program Based on If & Else

Program to input marks of five subjects and calculate percentage and grade according to following data

Input - Output

Input
Enter marks of five subject : 70 85 69 81 74

Output
Grade : B

Input
Enter marks of five subject : 60 54 40 61 24

Output
Grade : Fail

Algorithm

Step 1: START

Step 2: Input marks of five subject which store in variable like eng,hindi,math,sci and comp

Step 3: Calculate sum of all five subject as total with this formula :

    total = eng+hindi+math+sci+comp

Step 4: Calculate percentage with this formula P = (total / 500) * 100

Step 5: Calculate grade using these condition :

    if(per>90 && per<=100) then grade A+

    else if(per>80 && per<=90) then grade A

    else if(per>70 && per<=80) then grade B

    else if(per>60 && per<=70) then grade C

   else if(per>50 && per<=60) then grade 'Pass'

    else then grade "fail"

Step 6: END
