Study Notes

Introduction to C Programming

C was developed in the 1970s by Dennis Ritchie at Bell Telephone Laboratories, Inc.
The American National Institute of Standards (ANSI) developed a standardized definition of the C language.

Makefile and Compilation

Use I (lowercase L) to link libraries into the executable
Use I (capital i) to ignore errors when executing command scripts
make command executes the default target in the makefile called ‘Makefile’
make clean command removes the executable using the makefile
tar cvf.tar creates a tarfile, tar xf.tar extracts a tarfile

Input/Output

#include is used for input/output operations
fgets gets a string from the specified stream
gcc is the compiler used to compile files
Important flags: -g for debug, -Wall for printing all warnings, -o for specifying the executable file name, -lm for math library

Compiling Examples

gcc -o hello hello.c -lm compiles and links hello.c to executable hello
gcc hello.c -o hello -lm is an alternative way to compile and link
gcc hello.c compiles and links to a default executable a.out

Makefile Creation

A Makefile automates and manages the process of compiling programs
Use vi Makefile or vim Makefile to create a Makefile
Use # character for comments, and variable names like CC, CFLAGS, LIBS
Use $ character before variable names in targets, prerequisites, and recipes
