Enumeration(or enum) is a user defined data type in C. It is mainly used to assign names to integral constants, the names make a program easy to read and maintain. What data type is a pointer? data type of *p is pointer. And it points tointeger typevariable. It stores address in he...
In C programming language, the concept of pointers is the most powerful concept that makes C stand apart from other programming languages. In the part-I of this series we discussed the fundamental concepts around C pointers. In this article, we will try
Lets now compile the program : $ gcc -Wall constptr.c -o constptr constptr.c: In function ‘main’: constptr.c:7: error: assignment of read-only variable ‘ptr’ So we see that while compiling the compiler complains about ‘ptr’ being a read only variable. This means that we canno...
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 ...
Explanation: In the above program, pointer variable ptr stores the address of variable i. Then value and address of i along with the value of ptr are displayed. Note: The memory address displayed by the compiler can either be hexadecimal or a decimal number, depending on the compiler and th...
