C Exercises: Reverse a given array of integers and length 5

C-programming basic algorithm: Exercise-38 with Solution

Write a C program to reverse a given array of integers and length 5.

C Code:

#include <stdio.h>
#include <stdlib.h>
int main(void){ 
    int arr_size;
    int a1[] = {10, 20, 30, 40, 50};
    arr_size = sizeof(a1)/sizeof(a1[0]);
    printf("Elements in original array are: ");  
    print_array(a1, arr_size);
    int result[] = { a1[4], a1[3], a1[2], a1[1], a1[0] };
    arr_size = sizeof(result)/sizeof(result[0]);
    printf("\nElements in reverse array are: ");  
    print_array(result, arr_size);
    }     
 print_array(int parray[], int size)
  {
   int i;      
   for( i=0; i<size-1; i++)  
    {  
        printf("%d, ", parray[i]);  
    } 
   printf("%d ", parray[i]);  
   printf("\n");   
  }

Sample Output:

Elements in original array are: 10, 20, 30, 40, 50 

Elements in reverse array are: 50, 40, 30, 20, 10

C Programming: Tips of the Day

Why doesn't a+++++b work?

printf("%d",a+++++b); is interpreted as (a++)++ + b according to the Maximal Munch Rule!.

++ (postfix) doesn't evaluate to an lvalue but it requires its operand to be an lvalue.

! 6.4/4 says the next preprocessing token is the longest sequence of characters that could constitute a preprocessing token"
