Determine Output :void show() {    printf("PISTA ";     show();}void main() {    printf("CACHEW ");    return 10;}

The code you've provided seems to be written in C language. However, it contains a few errors and misconceptions. Here's a step-by-step analysis:

1. The show() function is a recursive function without a base case. This means it will call itself indefinitely, leading to a stack overflow error.

2. The main() function is declared as void, but you're trying to return an integer value 10. In C, the main() function should be declared as int if you want to return a value.

3. The printf("CACHEW "); statement will print "CACHEW " to the console.

4. The show() function is never called, so "PISTA " will never be printed.

5. If you correct the main() function to return an integer and call the show() function, the program will print "CACHEW " once and then go into an infinite loop printing "PISTA ", eventually leading to a stack overflow error.

Here's a corrected version of your code:

#include <stdio.h>

void show() {    
    printf("PISTA ");     
    // show(); // Commented to prevent infinite recursion
}

int main() {    
    printf("CACHEW ");    
    show();
    return 0;
}

This will print "CACHEW PISTA " to the console and then terminate successfully.
