奇怪的行为：GCC与math.h的兼容性问题

c
#include 
#include 
int main() {
    double num = 16;
    double result = sqrt(num);
    printf("The square root of %f is %f\n", num, result);
    return 0;
}

c
#include 
#include 
int main() {
    double base = 2;
    double exponent = -3;
    double result = pow(base, exponent);
    printf("%f raised to the power of %f is %f\n", base, exponent, result);
    return 0;
}
