1. (6 points) For each of the follow C++ code segments, mark it with CORRECT if it is correct and WRONG if it is NOT correct. You should consider both syntax and logical correctness. ________a)int array[4] ={ 0, 1, 2, 3, 4 }; _________b)int x[5];
x[0] = 0; _________c)void fn (const int x[ ] ) {
if ( x[0] < 0) x[0] = 0;
} _________d)char message[ ] = "Hello"; _________e)char message[6];
message = "Hello"; _________f)int array[2,3];

2. (10 points) The following program shows the result of a battle between the Taliban and Pashtun tribesmen in Afghanistan. The function call count(taliban) uses enumeration to store the values in the taliban array. What will the report function print on the screen?

#include <iostream.h>
#include <string.h>

enum {totalfighters, fighters, prisoners, dead, totaldead};
const int FIGHTERS = 500;

void count(int army[]);
// This function produces the values {221, 31, 19, 11, 160} when it is
// called with the taliban array.
// The values are {452, 146, 35, 39, 121} for the pashtun array.

void report(int army[], char name[], char city[]){
cout << "Current " << name << " dead: " << army[dead] << endl;
cout << "Current " << name << " prisoners: "
<< army[prisoners] << endl;
cout << "Remaining " << name << " fighters in " << city << ": "
<< army[fighters] << endl;
cout << "The " << name << " has lost " << army[totaldead]
<< " fighters." << endl;
cout << "Total remaining " << name << " fighters: "
<< army[totalfighters] << endl << endl;
}
int main () {
int taliban[5] = {FIGHTERS, 0, 0, 0, 0};
int pashtun[5] = {FIGHTERS, 0, 0, 0, 0};

count(taliban);
report(taliban, "Taliban", "Kandahar");
count(pashtun);
pashtun[totalfighters] += taliban[prisoners];
report(pashtun, "Pashtun", "Kandahar");
return 0;
}

Answer: Complete the following output produced by the report function:

Current Taliban dead: __________
Current Taliban prisoners: __________
Remaining Taliban fighters in Kandahar: __________
The Taliban has lost __________ fighters.
Total remaining Taliban
