# C Exercises: Store and retrieve elements from an array

## C Pointer : Exercise-7 with Solution

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

Pictorial Presentation:

Sample Solution:

C Code:

``````#include <stdio.h>
int main()
{
int arr1[25], i,n;
printf("\n\n Pointer : Store and retrieve elements from an array :\n");
printf("------------------------------------------------------------\n");
printf(" Input the number of elements to store in the array :");
scanf("%d",&n);

printf(" Input %d number of elements in the array :\n",n);
for(i=0;i<n;i++)
{
printf(" element - %d : ",i);
scanf("%d",arr1+i);
}
printf(" The elements you entered are : \n");
for(i=0;i<n;i++)
{
printf(" element - %d : %d \n",i,*(arr1+i));
}
return 0;
}
```
```

Sample Output:

``` Pointer : Store and retrieve elements from an array :
------------------------------------------------------------
Input the number of elements to store in the array :5
Input 5 number of elements in the array :
element - 0 : 5
element - 1 : 7
element - 2 : 2
element - 3 : 9
element - 4 : 8
The elements you entered are :
element - 0 : 5
element - 1 : 7
element - 2 : 2
element - 3 : 9
element - 4 : 8
```

## C Programming: Tips of the Day

How to format strings using printf() to get equal length in the output?

You can specify a width on string fields, e.g.

`printf("%-20s", "initialization..."); `

And then whatever's printed with that field will be blank-padded to the width you indicate.

The - left-justifies your text in that field.
