send HTTP Get request using Curl in c

Question

Please help me to implement an HTTP Get request using curl in C.

I need to hit URL with parameters like https://www.googleapis.com/tasks/v1/users?name=pradeep&lastname=singla I used CURLOPT_HTTPHEADER to set parameters with Header but without success. I implemented it like

struct curl_slist* contentheader = NULL;    

contentheader = curl_slist_append(contentheader, "name=pradeep");
contentheader = curl_slist_append(contentheader, "lastname=singla");

curl_easy_setopt(curl, CURLOPT_URL, "https://www.googleapis.com/tasks/v1/users");
curl_easy_setopt(curl, CURLOPT_HTTPHEADER, contentheader);
curl_easy_perform(curl);

In this case an error occured like "no correct APi request". So I thought that I can use

char *charff = "name=pradeep&lastname=singla";    
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, charfff);
curl_easy_setopt(curl, CURLOPT_HTTPGET, 1L); curl_easy_perform(curl);

but the same error is occurring.

Can anyone please help me ? I can put my request for both POST and GET method because server method may change anytime.

Why not simply add the parameters to the URL, like it's usually done? Like exactly what you have in the URL you show (https://www.googleapis.com/tasks/v1/users?name=pradeep&lastname=singla). — Some programmer dude

The URL is just a URL even with "parameters" and you set it in full with CURLOPT_URL.

They're not headers and they're not postfields.

CURL *curl = curl_easy_init();
curl_easy_setopt(curl, CURLOPT_URL, 
    "https://www.googleapis.com/tasks/v1/users?name=pradeep&lastname=singla");
curl_easy_perform(curl);
