How do I print a long printf?

How do I print a long printf?

Put an l (lowercased letter L) directly before the specifier. printf(“%ld”, ULONG_MAX) outputs the value as -1. Should be printf(“%lu”, ULONG_MAX) for unsigned long as described by @Blorgbeard below.

What is the format specifier for uint64_t?

for uint64_t type: #include h> uint64_t t; printf(“%” PRIu64 “\n”, t); you can also use PRIx64 to print in hexadecimal.

Is uint32_t the same as unsigned long?

You are likely wondering what are uint8_t, uint16_t, uint32_t and uint64_t. That’s a good question. Because it could be really helpul! It turns out that they are equal respectively to: unsigned char, unsigned short, unsigned int and unsigned long long.

What is format specifier for long in c?

%lu. Unsigned int or unsigned long. %lli or %lld. Long long.

How do I printf a long double?

%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 the difference between long long and long long int?

A long int is a signed integral type that is at least 32 bits, while a long long or long long int is a signed integral type is at least 64 bits. This doesn’t necessarily mean that a long long is wider than a long . Many platforms / ABIs use the LP64 model – where long (and pointers) are 64 bits wide.

Is Inttypes H standard?

The inttypes. h file is a C header file that is part of the C standard library and API. It was added with the 1999 version of the ISO C standard (known as C99). It includes the stdint.

How do I print long long integers?

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).

How do I Scanf long?

If you want to read into a long with scanf() , you need to use the %ld conversion specifier: long i; scanf(“%ld”, &i);

What C data type is uint32_t equivalent to?

Data Types and Sizes

Type Name Description
uint16_t 2 byte unsigned integer
uint32_t 4 byte unsigned integer
uint64_t 8 byte unsigned integer
uintptr_t Unsigned integer of size equal to a pointer

Do you put L before format specifier in printf?

Put an l (lowercased letter L) directly before the specifier. On most platforms, long and int are the same size (32 bits). Still, it does have its own format specifier: For 64 bits, you’d want a long long: Oh, and of course, it’s different in Windows:

How to format an unsigned long long int using printf?

A normal number is %d. “, sizeof (num), num, normalInt); return 0; } My number is 8 bytes wide and its value is 285212672l. A normal number is 0. I assume this unexpected result is from printing the unsigned long long int. How do you printf () an unsigned long long int? Use the ll (el-el) long-long modifier with the u (unsigned) conversion.

What is the format specifier to print a value of type std?

What is the format specifier to print a value of type std::uint64_t (from ) using functions from the std::printf () family in C++? C99 has PRIu64 (from ) but it’s not entirely clear to me that PRIu64 is valid C++11, although I could find hints that it may be.

How are characters displayed in printf and wprintf?

Display the argument as an address in hexadecimal digits. When used with printf functions, specifies a single-byte or multi-byte character string; when used with wprintf functions, specifies a wide-character string. Characters are displayed up to the first null character or until the precision value is reached.
