I need to write SampleExample.json file. you should write a simple program from scratch that will read in SampleExample.json and print out its contents. You should be able to accomplish this in 12-15 lines of code. There are two ways to print a json object. First, you can use std::cout to print output on a single line, like this:

std::cout << jsonObject; 

Putting this all together, if we use:

std::ifstream file; file.open("SampleExample.json"); nlohmann::json jsonObject; if (file.is_open()) { 

 file >> jsonObject; } 

std::cout << jsonObject; 

The output would be the following (Ive formatted this on two lines, but this will print a single line):

{"Sample1":[-319106570,811700988,1350081101,1602979228],"Sample2": [-319106570, 811700988,797039,-1680733532],"metadata": {"arraySize": 4,"numSamples": 2}}
