integer variable. In this guide, we will discuss pointers in C programming with the help of examples.

Program Output · Example · /* Demonstrating the sizeof operator */ #include <stdio.h> int main() { char c; /* define c */ short s; /* define s */ int i; /* define i */ long l; /* define l */ float f; /* define f */ double d; /* define d */ long double ld; /* define ld */ int array[ 20 ]; /* initialize array */ int *ptr = array; /* create pointer to array */ Example ·

Now, this particular structure is rather small compared to many used in C programs. To ... Consider the case described, i.e. we want a function that will accept as a parameter a · pointer to a structure and from within that function we want to access members of the · structure. For example we want to print out the name of the employee in our example

So it becomes necessary to learn pointers to become a perfect C programmer. Let's start learning them in simple and easy steps. As you know, every variable is a memory location and every memory location has its address · defined which can be accessed using ampersand & operator, which denotes an address in · memory. Consider the following example...
