MATLAB: How to write code processing grades

grade processinghomework

How do I write code that gets scores for 3 exams: Exam1, Exam2, Exam3 as input (via arguments). Prints them (nicely, using fprintf). Finds their average: Avg. Assigns a Grade according to the scale: A if Avg ≥ 90, B for 80 ≤ Avg < 90, and so on, down to F for Avg < 60. Finally, prints the Avg and Grade.

Best Answer

_I need to assign Grade to the letter grades so I can print out both the average and the letter grade._
A1=70. %an example adapt to your needs
A2='C'
formatSpec = 'Average is %d and grade is %s';
fprintf(formatSpec,A1,A2)

MATLAB: In for loop, All the students are getting same grades

You made the same mistake that people in the past have made asking this very same question.

Sum is an array so in a loop you need to use

Sum(i)

in all your elseif statements. You have a for loop looping round variable i, but you don't use i so you basically do the same thing every time round the loop.

There are neater ways to do it, but I'll ignore those for now and just do the minimal correction to the code you have.
