In this program, the elements are stored in the integer array data[]. Then, the elements of the array are accessed using the pointer notation. By the way, data[0] is equivalent to *data and &data[0] is equivalent to data data[1] is equivalent to *(data + 1) and &data[1] is ...
to pointer p. To get the address of a variable we use &p=&c;printf("\n This is the value of char c: %c ", c);//As we said, we use & to get the address. We are printing the memory address in which c is located:printf("\n This is the address...
Since, we cannot change the value of a constant but using pointer we can change it, in this program we are doing the same. Here, we have an integer constant and changing its value using pointer. Example /*C program to change the value of constant integer using pointers.*/#incl...

int x; int *ptr; *ptr=100; //assigning value ptr = &x; //initializing the pointer This code snippet is wrong; may cause run time error, because *ptr=100; is before the initialization of the pointer.Here is the right codeint x; int *ptr; ptr = &x; //initializing the pointer *...
Lets understand this through an example : char ch = 'c'; char *ptr = &ch *ptr = 'a'; In the above example, we used a character pointer ‘ptr’ that points to character ‘ch’. In the last line, we change the value at address pointer by ‘ptr’. But if this would have been...
The logical extension of the concept ofpassing a pointer to a functionleads to passing aUnionpointer, i.e., the pointer of amulti-dimensional array, passing the pointer of aself-referential structure, etc., all these have important uses in different application areas such as complex data struct...

1.The "Hello world!" program is often the first C program that a student of c writes.It prints hello world! followed by a newline on the standard output.This trivial(微不足道的) program is a good one to use when figuring out how to run the c compiler on your particular system. ...
