To implement the tasks you've mentioned, here is a sample code using C:
```c
#include <stdio.h>
#include <string.h>
#include <ctype.h>
void processArray(char *arr, int n) {
printf("nOriginal Array:n");
for (int i = 0; i < n; ++i) {
printf("%c ", arr[i]);
}
// Other functions to implement task requirements can be added here.
}
int main() {
char arr[100];
int n;
scanf("%d", &n);
fgets(arr, sizeof(arr), stdin);
processArray(arr, n);
return 0;
}
