Reverse Array in C
To reverse an array in C programming, you have to ask to the user
to enter the array size then array elements. Now start swapping the array elements. Make a temp
variable of same data type. Place first element in the
temp, then last element in the first, then temp in the last and so on.
C Programming Code to Reverse an Array
Following C program ask to the user to enter the size of the array then ask to enter the array elements to make the array
reverse, then display the reverse of the array on the screen:
/* C Program - Reverse an Array */
#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
int arr[50], size, i, j, temp;
printf("Enter array size : ");
scanf("%d",&size);
printf("Enter array elements : ");
for(i=0; i<size; i++)
{
scanf("%d",&arr[i]);
}
j=i-1; // now j will point to the last element
i=0; // and i will be point to the first element
while(i<j)
{
temp=arr[i];
arr[i]=arr[j];
arr[j]=temp;
i++;
j--;
}
printf("Now the Reverse of the Array is : \n");
for(i=0; i<size; i++)
{
printf("%d ",arr[i]);
}
getch();
}
When the above c program is compile and executed, it will produce the following output:
