What is the difference between \%D and \%C in C?
\%s refers to a string \%d refers to an integer \%c refers to a character. Therefore: \%s\%d\%s\%c\n prints the string “The first character in sting “, \%d prints i, \%s prints ” is “, and \%c prints str[0].
What is difference between \%D and \%U in C?
\%d is a signed integer, while \%u is an unsigned integer. Pointers (when treated as numbers) are usually non-negative.
What are the different format specifiers that you can use with the scanf function?
\%g , \%G : Scan a floating-point number in either normal or exponential notation. \%g uses lower-case letters and \%G uses upper-case. \%x , \%X : Scan an integer as an unsigned hexadecimal number. \%o : Scan an integer as an octal number.
What is the format specifier used to print address of a variable in C?
To print the memory address, we use ‘\%p’ format specifier in C. To print the address of a variable, we use “\%p” specifier in C programming language. There are two ways to get the address of the variable: By using “address of” (&) operator.
What is the use of U in C programming?
The commonly used format specifiers in printf() function are:
Format specifier | Description |
---|---|
\%u | It is used to print the unsigned integer value where the unsigned integer means that the variable can hold only positive value. |
What do you understand by format specifiers explain using a suitable program?
The format specifier is used during input and output. It is a way to tell the compiler what type of data is in a variable during taking input using scanf() or printing using printf(). Some examples are \%c, \%d, \%f, etc.
What are the different format specifiers used in C explain each one of them?
Using this concept the compiler can understand that what type of data is in a variable during taking input using the scanf() function and printing using printf() function….Format specifiers in C.
Format Specifier | Type |
---|---|
\%f | Float values |
\%g or \%G | Similar as \%e or \%E |
\%hi | Signed integer (short) |
\%hu | Unsigned Integer (short) |
What is the difference between \%I and \%D format specifiers in scanf?
But both format specifiers behave differently with the scanf function. The \%d format specifier takes the integer number as decimal but the \%i format specifier takes the integer number as decimal, hexadecimal or octal type. it means the \%i automatically identified the base of the input integer number.
What happens if I use \%P instead of P when formatting?
If you use \%p, it’ll just treat the value as a pointer’s memory address and prints it into hexadecimal. If you print the variable a instead of p, then you would get hexadecimal value of 5 when format specifier is \%p.
What is a format specifier in C programming?
Format specifiers in C. The format specifier is used during input and output. It is a way to tell the compiler what type of data is in a variable during taking input using scanf() or printing using printf().
What is the difference between \%D and \%P in C++?
As you already explained \%d is used for signed integers, while \%u is for unsigned integers. \%p is used to print pointer addresses. I think an example would be better to explain the difference. I am taking an example of a pointer, since it’ll explain the difference easily -.
