How do I reverse an array in C?

                                            How can we do reverse an array in C 

Logic to print array in reverse order:

1. Take the num and element of the array variable from the user.
2. Take I variable for looping.
3. Run the for loop from I=num-1 to I >=0 and decrement the value of I.
4. print the array element that is arr[i].

Let’s see an example of it:

       

#include<stdio.h> 
int main() 
{ 
int num , arr[num] , i; 
printf("Enter the size of an array:"); 
scanf("%d",&num); 
for(i=0;i<num;i++) 
{ 
scanf("%d",&arr[i]); 
}  
printf("Reverse of an array of the element:"); 
for(i = num-1; i >= 0; i--) 
{ 
printf("%d\n",arr[i]); 
} 
return 0; 
}
