int main() {
double sides[][2] = {
{3.0, 4.0},
{5.0, 12.0},
{8.0, 15.0}
};
double result;
for(int i = 0; i < 3; i++) {

printf("For sides %.2f and %.2f, the hypotenuse is: %.2f\n", sides[i][0], sides[i][1], result);
}
return 0;
}
输出结果为：
For sides 3.00 and 4.00, the hypotenuse is: 5.00
For sides 5.00 and 12.00, the hypotenuse is: 13.00
For sides 8.00 and 15.00, the hypotenuse is: 17.00
