Example of Array program in C
Array is a Type of Variable that can store Multiple Data at Time. Let we learn it today via Example of An array program Example of Array program in C
Program For Array in C
#include <stdio.h>
#include <stdlib.h>
void RotateLeftByOne(int arr[], int size)
{
int first = arr[0], index;
for(index = 0; index < size - 1 ; index++)
arr[index] = arr[index+1];
arr[index] = first;
}
void RotateLeft(int arr[], int d, int size)
{
for(int index = 0; index < d; index++)
RotateLeftByOne(arr, size);
}
void printArray(int arr[], int size)
{
for(int index = 0; index < size; index++)
printf("%d\t", arr[index]);
}
int main()
{
int *arr, size, d;
printf("Enter size of the array\n");
scanf("%d", &size);
printf("Enter elements in array\n");
for(int index = 0; index < size; index++)
scanf("%d", &arr[index]);
printf("Enter value of d\n");
scanf("%d", &d);
RotateLeft(arr, d, size);
printArray(arr, size);
return 0;
}
Two Dimensional Array in C
Output
Enter the size of the array 3
Enter elements in array
1
2
3
Enter the value of d 2
3 1 2
Array Program in C
| stdlib.h | void abort(void); | Stop a program abnormally. |
| stdlib.h | int abs(int n); | Calculates absolute value of an integer argument n. |
Else u can create a static array
int arr[10] ;
if the array size is not known and user-defined length is mentioned? then u can create a dynamic array or use some other data structure.
u can also do it like this, set the initial size say 100 items of the array then ask the user how many items u want between 1-100.

Otherwise, u can do a dynamic array (ReadHere).
