In this step-by-step tutorial, you'll learn how to use a popular library called JSON-C to parse a simple JSON document. We'll be writing all our code in ANSI C, so you can be sure that it will work with most compilers.

Simple and working with array content. Perfect.

Interestng. Grew up in FORTRAN in the 60s & the computer that I learned that on was about $3 Million. So it was going to be my Picket or nothing I thought. Long came the Commodor 64 in the early 80s, and my jaw dropped. Learened BASIC in an hour and all else is a hop, skip and a jump. C and C++ is just super. And as time passes it is getting more and more fun, and easier. This clip is an example of 'easier.' Thanks. Fine explaination.

Such a relaxed format of showing things! You HAVE to teach! Thanks for posting!

Thank you for your explanation. I didn't felt like reading docs.

You saved our project we have to hand in today. I love you dude.

@zdenekkouba2881 4 года назад

Nice. The only issue is that the newly create json objects need to be released at the end to avoid memory leaks. I know that in the case of your simple program every resource is released on exit. However, I would prefer your example to include the proper cleanup at the end. Just to stress the good practice..

@rtsa4633 2 года назад

Thanks for the heads up, which function do we use to free the json objects may I ask?

@manukumarputtaswamy8940 2 года назад

aby idea how to write jobj( json_object_to_json_string(jobj) ) in to file?

@bachelorlko Год назад

Correct. Neither pointers are freed.

@paolobelforte720 Год назад

No malloc was used, what memory you want to release?

@bachelorlko Год назад

@@paolobelforte720 When you create objects,they are allocated memory of their size.

How do you do the same on windows? If there is a way to install the json-c header file for windows. I have tried a few times but my compiler can't seem to find the header file

@JenipherCyberSecurity 4 года назад

Can you show sample of code for looping through a json file with multiple values? You showed with a file with single value. For example, in your file if you had like 10 names?

@werner94fribourg 4 года назад

Thanks for your video, but I have a question : Can you explain me how we create and add a new object to a json structure (modify the file directly). Thanks in advance for your answer. It will be very cool if you make a complete tutorial about all the functionalities that this library contains

@MaheshKumar-lq1xm 4 года назад

Is json parsing soo difficult that you have use an external library ?

@JonHarris77 3 года назад

Perhaps not in the trivial case he used, but it can be a lot more complicated. But, sure you can re-invent the wheel if you want to.

Did you really compile this? Friend is a keyword and it won't compile. And after i change var name, still execution brings segfault.

@dmytrolytvynenko6537 5 лет назад

friend is a keyword in C++, not in C.
