The hypotenuse function is correct, but the main function has a problem. Explain why it may not work, and show a way to fix it. Your fix must be to the main function only; you must not change the hypotenuse function in any way.

#include

#include

using namespace std;

void hypotenuse(double leg1, double leg2, double* resultPtr)

{

*resultPtr = sqrt(leg1*leg1 + leg2*leg2);

}

int main()

{

double* p; hypotenuse(1.5, 2.0, p); cout << "The hypotenuse is " << *p << endl;

}

d. The match function is supposed to return true if and only if its two C string arguments have exactly same text. Explain what the problems with the implementation of the function are, and show a way to fix them. // return true if two C strings are equal

bool match(const char str1[], const char str2[]) { while (str1 != 0 && str2 != 0) // zero bytes at ends

{

if (str1 != str2) // compare corresponding characters return false; str1++; // advance to the next character str2++;

}

return str1 == str2; // both ended at same time?

}

int main()

{

char a[10] = "pointy"; char b[10] = "pointless";

if (match(a,b)) cout << "They're the same! ";

}
