C program to print the element at the given position in an array

Write a C program to print the element at the given position in an array.


  #include <stdio.h>
  #define MAXLIMIT 256

  int main() {
        int i, n, pos, data[MAXLIMIT];

        /* get the number of elements from the user */
        printf("Number of elements:");
        scanf("%d", &n);

        /* boundary check */
        if (n > MAXLIMIT || n < 0) {
                printf("Boundary Limit Exceeded!!\n");
                return 0;
        }

        /* get the elements in the input array */
        printf("Enter elements of your array:\n");
        for (i = 0; i < n; i++) {
                printf("Data[%d]: ", i);
                scanf("%d", &data[i]);
        }

        /* get the desired position */
        printf("Enter your desired position:");
        scanf("%d", &pos);

        /* boundary check */
        if (pos > n || pos < 1) {
                printf("Wrong Position!!\n");
                return 0;
        }

        /* printing the result */
        printf("Element at the given position is %d\n", data[pos - 1]);
        return 0;
  }



  Output:
  jp@jp-VirtualBox:~/$ ./a.out
  Number of elements:5
  Enter elements of your array:
  Data[0]: 100
  Data[1]: 200
  Data[2]: 300
  Data[3]: 400
  Data[4]: 500
  Enter your desired position:4
  Element at the given position is 400
