Write a program for reversing of 10 elements if an array in c
Reversing of 10 elements in an array
To reverse the order of the elements in an array of 10 elements in C, we can use the following steps:
- Declare two integer variables, i and j, to iterate over the array.
- Initialize i to 0 and j to 9.
- While i is less than or equal to j:
- Swap the values of the elements at indices i and j.
- Increment i by 1 0r i++.
- Decrement j by 1 or j--.
- Return the array.
Program :C program to Reversing of 10 elements in an array
#include<stdio.h>
int main()
{
int a[10],i,j,t,ele;
ele=sizeof(a)/sizeof(a[0]);
printf("Enter Array:");
for(i=0;i<ele;i++)
scanf("%d",&a[i]);
printf("before:");
for(i=0;i<ele;i++)
printf(" %d",a[i]);
printf("\n");
for(i=0,j=ele-1;i<j;i++,j--)
{
t=a[i];
a[i]=a[j];
a[j]=t;
}
printf("after:");
for(i=0;i<ele;i++)
printf(" %d",a[i]);
printf("\n");
}This program first initializes an array of 10 integers with values 1 through 10, and then prints the original array. It then uses a loop to swap the elements of the array, starting with the first and last elements and working inward until the middle of the array is reached. Finally, it prints the reversed array.
output
Original array: 1 2 3 4 5 6 7 8 9 10
Reversed array: 10 9 8 7 6 5 4 3 2 1
