C(++) starting point

Lets start with a simple “Hello World”

#include <stdio.h>

int main() {
    printf("Hello, World!\n");
    return 0;
}

Now we have two popular compiler suites

1. GCC and
2. LLVM

For GCC the next steps are

gcc -c hello.c

gcc -o hello hello.o

For LLVM alternatively as follows

clang -c hello.c

clang -o hello hello.o

And a respective Make file looks like the following

CC = clang
CFLAGS = -Wall

all: hello

hello: hello.o
    $(CC) $(CFLAGS) -o hello hello.o

hello.o: hello.c
    $(CC) $(CFLAGS) -c hello.c

clean:
    rm -f hello hello.o

For C++ the program looks like the following

#include <iostream>

int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

Compiling and linking via GCC

g++ -o hello hello.cpp

Via LLVM as follows

clang++ -o hello hello.cpp

Debuggern happens via

GCC

gbd

And LLVM

lldb
