How do I print a long in C?
%Lf format specifier for long double %lf and %Lf plays different role in printf. So, we should use %Lf format specifier for printing a long double value.
What is a long number in C?
Long is a data type used in programming languages, such as Java, C++, and C#. A constant or variable defined as long can store a single 64-bit signed integer. Therefore, if a variable or constant may potentially store a number larger than 2,147,483,647 (231 ÷ 2), it should be defined as a long instead of an int.
How do you print a long value in C++?

How do I print long long int using printf?
How to read and print large integer numbers in C?
In this c program, we will learn how to handle large integer numbers – here we are going to learn how to read and print large integer number in c programming language?

Which is the best way to print a long int?
You must use %ld to print a long int, and %lld to print a long long int. Note that only long long int is guaranteed to be large enough to store the result of that calculation (or, indeed, the input values you’re using).
Can you print a 10 byte long double in C?
printf and scanf function in C/C++ uses Microsoft C library and this library has no support for 10 byte long double. So when you are using printf and scanf function in your C/C++ code to print a long double as output and to take some input as a long double, it will always give you wrong result.
