3. Vorlesung

• video @youtube.de; slides @uni-freiburg.de; Exercise Sheet @uni-freiburg.de; code from the lecture @uni-freiburg.de

• fundamental constructs: see slides

• make graphical terminal output witch ascii escape sequences

• to write a gat row 20, collumn 60:

printf("x1b[20;60Hg");

• IO with ncurses libary

• wait microseconds with usleep (from unistd.h)

• to clean with ncurses:

endwin()

• declare global variables in header files, and include in source file. Declare with the extern keyword. Initialize in source file
• in the makefile:
  • use generic rules; Example for the test:

%Test: %.o %Test.o
   g++ -o $@ -x $ -lgtest -lpthread

• use make all
• use variables for compiler and compiler options
• let all .o files depend on all headers and the corresponding header file
• to avoid declaring the main function in the test, use -lgtest_main
• to make a rectangle add an inverted space (see ascii escape codes)
