Pointer Arithmetic pointers also follow the Arithmetic Operations as the normal Int or Float Variables follow but there is a slight difference. Consider the following example: int i, *ptr; ptr i; ptr ptr 1; what do you think, what will happen? Int occupies 4 Bytes of space on memory. So, when we declare Int i, 4 Bytes of space will be allocated. Now, we assign ptr the address of that location. Byte 0 50122 Byte 1 50123 Byte 2 50124 Byte 3 50125 The values 50122, 50123 etc are the arbitrary assigned values to the memory location.
Ptr contains the value 50122. The operation ptr 1 will move the pointer to next memory location. Now, pointer will not point to 50123 rather it will point to 50122. As this is Integer pointer and size of an Integer is 4 Bytes. We will use this a lot when we will go to the chapter Arrays. Call by reference: When we pass address to a function the parameters receiving the address should be pointers. The process of calling a function by using pointers to pass the address of the variable is known as call by reference. The function which is called by reference can change the values of the variable used in the call.

Hence, int x 9; x) will give the value of x itself. As x will return the address and address) will return content at that address. I hope writings this has cleared your doubts about and * signs. If not, read this again. H void main int i, roles *intptr; printf(Enter some value of i: scanf(d, i intptr i; printf(nThe value of i is d, which is stored in u memory address.,i, i printf(nThe value of i is d, which is stored in u memory address. Intptr, intptr getch return; When you will execute this program, youll see that the outputs generated by second and third printf statements are the same. Now you know the reason.
Now in the next statement, ptr is assigned a memory address. This means now, the pointer Variable ptr will point to the memory location which contains the variable. In the next statement, y*ptr, we assign y a value which is equal to the value stored in the memory location pointed by ptr. If this is confusing for you, ill make it simple. When we declare a pointer, we always assign what type of values it will point. This means, whether it will point to an integer, or a float or a char or a structure. Then we initialize our pointer by giving this address of a memory location, this is done by operator. x means, address in memory where x is stored. Putting * before a pointer will return you the value stored in that memory location.essay
that Variable. This reference to a variable can be obtained by preceding the identifier of a variable with an ampersand sign ( known as reference operator and which can be literally translated as "address of". The and * Signs Consider the following statements: int x, y; int *ptr; x 2; ptr x; y *ptr ; Now, i shall tell you what the meanings of these statements are. Firstly, we declared two integer Variables x and y and a pointer to integer ptr. The * sign means we are declaring a pointer that points to an integer. In other words, we can say that the pointer ptr will always point to a memory location which will contain integer. After this, we assign x a value (2 in this case).
It sets up a symbol table. In that table it adds the symbol i and the relative address in memory where those 4 bytes were set aside. The value 5 will be placed in that memory location reserved for the storage of writings the value. In a sense there are two values associated with the object. One is the value of the integer stored there and the other the value of the memory location,. E., the location. A, pointer is a, variable that contains the memory location of another. You start by specifying the type of data stored in the location identified by the.

If you really want to be good. C programming, pointer is the must. In this chapter well learn in detail about the. Pointers and its usage in, c Programming. When we declare a, variable we inform the compiler of two things, the name of the. Variable and the type of the, variable. For example, we declare. Variable of type integer with the name i by writing: Int i 5; What happens when the compiler sees this? The, compiler sets aside 4 bytes of memory to hold the value of the integer.
