Question :- 

Write a Program to store n elements in an array and print the elements using pointers

Code :-


// 6. Write a program to store n elements in an array and print the
//elements using pointer.

#include<stdio.h>

void main()
{
    // declare array and pointer variable
    int a[5],i;
    int *p;

    // collect values from user and store them in an array

    for (i = 0 ; i < 5 ; i++)
    {
        printf("\n Enter Number :- ");
        scanf("%d",&a[i]);
    }

    // assign the address of array's first number

    p = &a[0];

    // print values of array

    printf("\n\nPrinting Values of array a\n");

    for (i = 0 ; i < 5 ; i++)
    {
        printf("\n a[%d] = %d",i,*p);
        p++;
    }
}


Description :-

  • In This Program our query is to store n Elements is an array using pointers and also print them.
  • In Previous Practical Videos we learn that how to store memory address of any variables and print them
  • Now we have to store memory address in an array and print them.
  • For that, First we required one integer array to store some values.
  • Also we have to declare one extra variable to run a loop, so that we don't have to write printf and scanf statements .
  • Then we will declare one pointer variable to store memory address.
  • Using for loop or any other loop we will assign some values to the intger array.
  • After assigning values to the array we will assign the memory address of first element of array,
    • for ex. pointer variable p = array a[0] (value at 0th or first index)
  • We don't have to assign addresses of all elements of array, only first element is required for that.
  • Now using for loop again, we will print the values of array but now we will print them using pointer variable.
  • In for loop, we will increment the address of pointer variable so that it will move to the next element of array.

   YouTube Video :-  Question :-  Write a Program to Find a Maximum Number using Pointer's Code :- #include <stdio.h> void main() {     // declaring Variables     int a,b;     int *p,*p1;     // Initilize Values     printf( "Enter First Number : " );     scanf( "%d" ,&a);     printf( "\nEnter Second Number : " );     scanf( "%d" ,&b);     // assign address of two varriables to the pointer variable     p = &a;     p1 = &b;     if (*p > *p1)     {         printf( "%d is Maximum " ,*p);     }     else     {         printf( "%d is Maximum " ,*p1);     } } Description :- In this Program , we have to find a maximum number from two numbers using pointers. First we will declare two integer variables for storing the values. Then we will declare two pointers variable, so that we can store the memory addresses of two variables (Because in our query we have find maximum number using pointer's) For comp
