C Pointer Example Program

C program to find the number of vowels consonants digits and white spaces in a string.

C pointer example program. C pointer example programs. Program to create initialize assign and access a pointer variable. The variable that stores the address of another variable like foo in the previous example is what in c is called a pointer. List of c programs using pointers covered here the c.

By doing so a programmer could change which object a method was working on. C program to swap numbers in cyclic order using call by reference. The only difference between pointers of different data types is the data type of the variable or constant that the pointer points to. C program to find the frequency of characters in a string.

Simple program for print address of variable using pointer in c. Like regular variables pointers have a data type. Simple pointer example program in c. In the early version of c would let this pointer to be changed.

Program to swap two numbers using pointers. Using pointers in c. Since pc and c are not initialized at initially pointer pc points to either no address or a random address. Program to change the value of constant integer using pointers.

The syntax simply requires the unary operator for each level of indirection while declaring the pointer. This feature was eventually removed and now this in c is an r value. Program to count vowels and consonants in a string using pointer. Program to print a string using pointer.

C program to access elements of an array using pointer. This collection of solved concept based examples on c programming will be very useful for beginners in c programming language.

For a c program the memory of a computer is like a succession of memory cells each one byte in size and each with a unique address.
