EXERCISE IN CLASS CHAPTER 3
PART 1 IDENTIFIER
SCENARIO 1 • record1 • 1record • file_3 • return • $tax • Name • name and address • name-and-address • name_and_address • 123-45-6789 Determine which of the following are valid identifiers. If invalid, explain why.
SCENARIO 2 #include <stdio.h> void main() { int1st, second, third; float fun, Fun; char x, initial name, my-name; Second = 8; Fun=10.2 fun = x; } Trace all the syntax error(s) in below program:
PART 1 BASIC DATA TYPE
SCENARIO 1 Write appropriate declarations and assign the given initial values for each group of variables: • Floating-point variables: a = -8.2, b = 0.005 • Integer variables: x = 129, y = 87, z = -22 • Character variables : c1 = ‘w’, c2 = ‘&’
SCENARIO 2 Identify the syntactic errors in the following program. Then rewrite the correct program. #include <stdio.h> void main() • { integer a; • floating-point b; • character c; • printf(“End.”); }
SCENARIO 3 • Write the #define preprocessor directive for a program that has the constant macro HOURLY_WAGES (5.50). • Rewrite the following program that uses variables with memory constants. • #include<stdio.h> • void main() • { float weight = 30.5; • intproduct_code = 1000;}
