WAP for insert an element at desired position in an array?

 #include <stdio.h>  
 int main()  
 {  
   int array[200], pos, a, n, val;  
   printf("Enter number of elements in array\n");  
   scanf("%d", &n);  
   printf("Enter %d elements\n", n);  
   for (a = 0; a< n; a++)  
    scanf("%d", &array[a]);  
   printf("Enter the location where you wish to insert an element\n");  
   scanf("%d", &pos);  
   printf("Enter the value to insert\n");  
   scanf("%d", &val);  
   for (a = n - 1; a >= pos - 1; a--)  
    array[a+1] = array[a];  
   array[pos-1] = val;  
   printf("Resultant array is\n");  
   for (a= 0; a<= n; a++)  
    printf("%d\n", array[a]);  
   return 0;
