Print string using pointers


Write a C program to Print string using pointers. Here’s simple program to Print string using pointers in C Programming Language.


What are Pointers?


A pointer is a variable whose value is the address of another variable, i.e., direct address of the memory location. Like any variable or constant, you must declare a pointer before using it to store any variable address.

The general form of a pointer variable declaration is

  • type *var-name;

Here, type is the pointer’s base type; it must be a valid C data type and var-name is the name of the pointer variable.

The asterisk * used to declare a pointer is the same asterisk used for multiplication. However, in this statement the asterisk is being used to designate a variable as a pointer.

The unary or monadic operator & gives the “address of a variable’”.

The indirection or dereference operator * gives the “contents of an object pointed to by a pointer”.


Below is the source code for C program to Print string using pointers which is successfully compiled and run on Windows System to produce desired output as shown below :


SOURCE CODE : :


/*  C program to Print string using pointers  */

#include <stdio.h>
int main()
{
    char str[100];
    char *ptr;

    printf("Enter any string :: ");
    scanf("%s",str);

    //assign address of str to ptr
    ptr=str;

    printf("\nThe entered string is :: ");

    while(*ptr!='\0')
        printf("%c",*ptr++);

    return 0;
}

 


Output : :


/*  C program to Print string using pointers  */

Enter any string :: CodezClub

The entered string is :: CodezClub

Process returned 0

Above is the source code for C program to Print string using pointers which is successfully compiled and run on Windows System.The Output of the program is shown above .
