C Exercises: Change the array elements

C Basic Declarations and Expressions: Exercise-127 with Solution

Write a C program that reads an array of integers (length 8), replace the 1st element by the 8^th, 2^nd by the 7^th and so on. Print the final array.

Sample Solution:

C Code:

#include <stdio.h>
int main ()
{
  unsigned short i, j;
  short array_nums[8], n, temp1, temp2;
  printf("Input 8 array elements:\n");
  for (i = 0; i < 8; i++)
  {
    scanf("%hd", &n);
    array_nums[i] = n;
  }

  for (i = 0, j = 7; i <= 4 && j >= 4; i++, j--)
  {
    temp1 = array_nums[i];
    temp2 = array_nums[j];
    array_nums[i] = temp2;
    array_nums[j] = temp1;
  }
 printf("\nModified array:\n");
  for (i = 0; i < 8; i++)
    printf("array_nums[%d] = %d\n", i, array_nums[i]);
}

Sample Output:

Input 8 array elements:
25
35
17
-5
29
45
60
65

Modified array:
array_nums[0] = 65
array_nums[1] = 60
array_nums[2] = 45
array_nums[3] = 29
array_nums[4] = -5
array_nums[5] = 17
array_nums[6] = 35
array_nums[7] = 25
