I have some data like
{
"GLOBAL DATA":
{
"FIRST": [
{"BEGIN": "0", "END" : "100"}
],
"SECOND":"SomeData",
"THIRD":"SomeMoreData"
}
}
I want to add more data to FIRST
array.
I tried creating the insertion data as follows
json v2 = {"BEGIN": "200","END" : "300"};
But this gives error
example1.cpp:34:23: error: expected '}' before ':' token json v2 = {"BEGIN": "200","END" : "300"};
What's the issue with my v2
data?
You could wrap the JSON data in a raw string literal and use the _json
user-defined literal to parse it:
json v2 = R"({"BEGIN": "200", "END": "300"})"_json;
Or you could make it directly (without parsing), but using valid C++ syntax:
json v2 = {{"BEGIN", "200"}, {"END", "300"}};
