Before starting with this tutorial we assume that you are best aware of the following C programming topics:

• Operators in C Programming.
• Basic Input and Output function in C Programming.
• Basic C programming.
• For loop in C Programming.
• Using pointer in C programming.

•  Program:

#include<stdio.h>

int main()
{
    int data[5];
    printf("Enter the elements: \n");
    for(int i=0; i<5; ++i)
    scanf("%d", data+i);

    printf("You entered: \n");
    for(int i=0; i<5; ++i)
    printf("%d\n", *(data+i));
    return 0;
}

•  Output:

• Visit:

• Program:

#include<stdio.h>
#include<conio.h>
#include<string.h>
void main()
{

    char str[30]="Goeduhub Technologies";
    char c='A';
    int i;

    char *ptr_str[30];
    char *ptr_c=&c;

    for(i=0;i<strlen(str);i++)
    ptr_str[i]=&str[i];


    //Printing value and address of variables on output window
    printf("\nString Entered is : %s\n Address of string :",str);
    for(i=0;i<strlen(str);i++)
    printf("\n%c's address : %p",str[i],ptr_str[i]);
    printf("\nValue of c = %c\nAddress of c = %p",c,ptr_c);
    getch();
}

• Output:

•  Program:

#include<stdio.h>
#include<conio.h>
    
void main()
{

//Declaration of variables and pointer variables
int x,y,*ptr_x,*ptr_y,temp;  

//Insert value of x and y
printf("Enter the value of x and y\n");
scanf("%d%d", &x, &y);

//Printing value before swapping
printf("Before Swapping\nx = %d\ny = %d\n", x, y);

//Assigning address of variables to pointers
ptr_x = &x;
ptr_y = &y;

//Swapping pointer address with the help of temp variable
temp = *ptr_y;
*ptr_y = *ptr_x;
*ptr_x = temp;

//printing values of x and y
printf("After Swapping\nx = %d\ny = %d\n", x, y);
getch();
}

•  Output:

pointer_vaibale = &variable;
