Now, before we can execute the hello.c program, recall that we must compile it with a compiler, translating it from source code into machine code (i.e., zeroes and ones). Execute the command below to do just that:
make hello
And then execute this one again:
ls
This time, you should see not only hello.c but hello listed as well? You’ve now translated the source code in hello.c into machine code in hello.
Now execute the program itself by executing the below.
./hello
Hello, world, indeed!
Suffice it to say, no matter how you compile or execute this program, it only ever prints hello, world. Let’s personalize it a bit, just as we did in class.
Modify this program in such a way that it first prompts the user for their name and then prints hello, so-and-so, where so-and-so is their actual name.
As before, be sure to compile your program with:
make hello
And be sure to execute your program, testing it a few times with different inputs, with:
./hello
Execute the below to evaluate the correctness of your code using check50. But be sure to compile and test it yourself as well!
check50 cs50/problems/2021/x/hello
Execute the below to evaluate the style of your code using style50.
style50 hello.c
Execute the below to submit your work.
