curl in C without libcurl

Question

I try tu run curl in C with this command (without libcurl) curl -X GET "https://dex.binance.org/api/v1/klines?symbol=&interval=&limit=&startTime=&endTime=

I created this script (in linux mint)

#include <stdlib.h>
int status = system("curl -X GET \"https://dex.binance.org/api/v1/klines?symbol=&interval=&limit=&startTime=&endTime=\"");

when I compile, I get this error:

test.c:3:14: error: initializer element is not constant
    3 | int status = system("curl -X GET \"https://dex.binance.org/api/v1/klines?symbol=&interval=&limit=&startTime=&endTime=\"");
      |              ^~~~~~

Anyone can explain me why return this error?

Answer 1

You need a main function in C. This is covered in the first chapter of your C text book.

You probably want something this:

#include <stdlib.h>

int main()
{
   int status = system("curl -X GET \"https://dex.binance.org/api/v1/klines?symbol=&interval=&limit=&startTime=&endTime=\"");
   ...
}
