    return (count);
}

Numerical answer

Single correct

• Ap = n * (n-1) * (n-2) / 6;
• Bp = n * (n-1) / 2 * (n-2) / 3;
• Cp = n * (n-1) / 3 * (n-2) / 2;
• Dp = n * (n-1) * (n-2) / 6.0;

int f(int j)
{
    static int i = 50;
    int k;
    if (i == j)
    {
        printf("something");
        k = f(i);
        return 0;
    }
    else return 0;
}

Single correct

• AThe function returns 0 for all values of j.
• BThe function prints the string something for all values of j.
• CThe function returns 0 when j = 50.
• DThe function will exhaust the runtime stack or run into an infinite loop when j = 50.
