+Quick Exercise — Variables
+
+Try writing a small script (your language of choice) that:
+
+Asks the user for their name.
+
+Accept the name only if:
+1. Length ≤ 20
+2.First character is a letter
+3.Contains no digits
+4.Contains no spaces
+
+This tests:
+✔ Reading input
+✔ Using variables
+✔ Printing output
+
+Reply here with your solution — I’ll give feedback.
+
+I will use c for this exercises
