    return 0;
}

A
0
B

135
B
+INF
C
-121
D
-8


Question 8

    return 0;
}

A
Yes
B
No
C
Compiler Error
D

A
p = n * (n-1) * (n-2) / 6;
B
p = n * (n-1) / 2 * (n-2) / 3;
C
p = n * (n-1) / 3 * (n-2) / 2;
D
p = n * (n-1) * (n-2) / 6.0;



Question 10

#include<stdio.h>
int main()
{
    float x = 0.1;
    if ( x == 0.1 )
        printf("IF");
