Tasks

  1. Object-like Macro : A header file that defines a macro named SIZE as an abbreviation for the token 1024.
    • Compile the code this way: gcc -Wall -pedantic -Werror -Wextra -std=gnu89 0-main.c -o a
  2. Pi : A header file that defines a macro named PI as an abbreviation for the token 3.14159265359.
    • Compile the code this way: gcc -Wall -pedantic -Werror -Wextra -std=gnu89 1-main.c -o b
  3. File name : A program that prints the name of the file it was compiled from, followed by a new line.
    • You are allowed to use the standard library.
    • Compile the code this way: gcc -Wall -pedantic -Werror -Wextra -std=gnu89 2-main.c -o cc
    • Then you can try and create a copy of 2-main to 02-main.c then recompile this way: gcc -Wall -pedantic -Werror -Wextra -std=gnu89 02-main.c -o cc
  4. Function-like macro : A function-like macro ABS(x) that computes the absolute value of a number x.
    • Compile the code this way: gcc -Wall -pedantic -Werror -Wextra -std=gnu89 3-main.c -o d
  5. SUM : A function-like macro SUM(x, y) that computes the sum of the numbers x and y.
    • Compile the code this way: gcc -Wall -pedantic -Werror -Wextra -std=gnu89 4-main.c -o e
