Array store all data in array on the basis of index. For reverse an array element you nedd to interchange elements of array on the basis of index value. .
C++ Program to Reverse an Array
#include<iostream.h> #include<conio.h> void main() { int a[20],b[20],i,j,n; clrscr(); cout<<"How many elements you want to enter: "; cin>>n; cout<<"Enter any "<<n<<" elements in Array: "; for(i=0; i<n ;i++) { cin>>a[i]; } cout<<"Reverse of Array: "; for(i=n-1,j=0; i>=0;i--,j++) { b[i]=a[j]; } for(i=0; i<n ;i++) { cout<<b[i]; } getch(); }
Output
How many elements you want to enter : 5 Enter any 5 elements in Array: 1 4 2 7 5 Reverse of Array: 5 7 2 4 1
