Project 2: Grade Calculator

Read scores, compute an average, and show a letter.

Outline

1. Ask how many scores.
2. Loop and sum them.
3. Compute average.
4. Map to a letter:

if (avg >= 90)      printf("A");
else if (avg >= 80) printf("B");
else if (avg >= 70) printf("C");
else                printf("F");

Pseudocode

score total = 0
for i in 1..count:
     total += input
avg = total / count
pick letter from avg

Extend

• Handle 0 scores.
• Also print the average.
• Support decimals with %f.

TL;DR

• Accumulate in a loop.
• Divide to average.
• Chain else-if buckets for the letter.
