How do you print an address 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.
How do I print a pointer address?
Printing pointers. You can print a pointer value using printf with the \%p format specifier. To do so, you should convert the pointer to type void * first using a cast (see below for void * pointers), although on machines that don’t have different representations for different pointer types, this may not be necessary.
What format specifier is used for address of a variable?
To output address of a variable, \%p format specifier is used.
How will you get address of a variable in C?
In C, we can get the memory address of any variable or member field (of struct). To do so, we use the address of (&) operator, the \%p specifier to print it and a casting of (void*) on the address.
How do I print a pointer address without printf?
If you want to print the value of a pointer without using the format \%p specifier, you can cast the pointer to an integer that has the same size and then print the integer value. int x; Serial.
How do I print my printf address?
The format to print output in C is given as – printf(“”, ). The address of a variable is an integer numeric quantity and the format specifier used to print such a quantity is “\%p” (for printing address in hexadecimal form) and “\%lld” (for printing address in decimal form).
Why P is used in C?
It’s purpose is to print a pointer value in an implementation defined format. The corresponding argument must be a void * value. And \%p is used to printing the address of a pointer the addresses are depending by our system bit.
How to print the address of a variable in C programming language?
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.
How to get the address of another variable in C++?
When we want to get the address of any variable, we can use “address of operator” (&) operator, it returns the address of the variable. A pointer is the type of a variable that contains the address of another variable, by using the pointer; we can also get the address of another variable. Note: At every run output may change.
Why can’t I print the address of a function pointer?
It’s right there in the warning: ISO C forbids conversion of a function pointer to an object pointer type, which includes void*. See also this question. You simply can’t print the address of a function in a portable way, so you can’t get rid of the warning.
What is the difference between \%X and \%P when writing address?
You can use \%x or \%X or \%p; all of them are correct. If you use \%x, the address is given as lowercase, for example: a3bfbc4 If you use \%X, the address is given as uppercase, for example: A3BFBC4 Both of these are correct.
