Can we store the address of a float variable in integer pointer variable?

A Simple Example of Pointers in C Important point to note is: The data type of pointer and the variable must match, an int pointer can hold the address of int variable, similarly a pointer declared with float data type can hold the address of a float variable.

What is the difference between integer pointer and float pointer?

Float pointer All concepts are similar to the integer pointer. If you are directly reading this article, kindly go through the integer pointer topic before getting started with this. Data type is the only difference. A float pointer only stores an address of a float variable.

Why do you store address in a pointer Why not value in a pointer?

So a pointer really only stores the memory address. Information about the size of the pointee is in the type (just as a non-pointer variable’s type tells the compiler how large that variable is). Make sure you don’t confuse what the hardware does with what the compiler does.

Can you store a float in an int?

So you cannot store a float value in an int object through simple assignment. You can store the bit pattern for a floating-point value in an int object if the int is at least as wide as the float , either by using memcpy or some kind of casting gymnastics (as other answers have shown).

Can pointer stored in an integer variable?

A pointer is a variable that stores the address of another variable. Unlike other variables that hold values of a certain type, pointer holds the address of a variable. For example, an integer variable holds (or you can say stores) an integer value, however an integer pointer holds the address of a integer variable.

What can be stored in an integer variable?

An integer is a type of value that can be stored in a variable. Integers are whole numbers that can be positive, negative, or zero. Definition: Integers are values written and stored as numbers and are often called “ints”. Integers are used to store values and run loops.

Can float and int be compared?

As to the first question about whether the comparison is valid, the answer is yes. It is perfectly valid. If you want to know if a floating point value is exactly equal to 3, then the comparison to an integer is fine. The integer is implicitly converted to a floating point value for the comparison.

Is float better than int?

Integers and floats are two different kinds of numerical data. An integer (more commonly called an int) is a number without a decimal point. A float is a floating-point number, which means it is a number that has a decimal place. Floats are used when more precision is needed.

Does pointer store the address of variable?

A pointer is a variable that stores a memory address. Pointers are used to store the addresses of other variables or memory items. Pointers are very useful for another type of parameter passing, usually referred to as Pass By Address. Pointers are essential for dynamic memory allocation.

Why are void pointers bad?

Void pointers have too little information meaning that you literally can’t do anything with them. You can only cast them to another pointer based on extra data. If you find some code that casts a void pointer unconditionally to another pointer, there should have never been a void pointer in the first place.

Why use an int over a float?

Another reason to favour integers over floats is performance and efficiency. Integer arithmetic is faster. And for a given range integers consume less memory because integers don’t need to represent non-integer values. Another reason is to show intent.

What does int do to a float?

Yes, an integral value can be added to a float value. The basic math operations ( + , – , * , / ), when given an operand of type float and int , the int is converted to float first. So 15.0f + 2 will convert 2 to float (i.e. to 2.0f ) and the result is 17.0f .

Is it possible to store a pointer value in an integer?

Pointers are not integers. If you want to store a pointer value, you should almost always store it in a pointer object (variable). That’s what pointer types are for.

What is the difference between an INT* AND FLOAT* pointer?

As for the question in your title, pointers of type int* and float* are of different types. An int* should point to an int object; a float* should point to a float object. Your compiler may let you mix them, but the result of doing so is either implementation-defined or undefined.

Is it OK to assign int values to float values?

That’s ok. p = &q pis of type int*; &qis of type float*. Assigning one to the other (without a cast) is a constraint violation. The simplest way to look at it is that it’s simply illegal.

Can the data type of a pointer be the same as variable?

The data type of pointer must be same as the variable, which the pointer is pointing. Why is it important that a pointer variable should contain the address of a variable of the same data type?
