C++模板在取三个数最小值时使用出错

Question

在用模板取三个数中最小的数时在另一个.h文件跳出来了一个代码报错，求解是什么问题。感谢！

Answer 1

#include <iostream>

using namespace std;

template <typename T>
T min(T a, T b, T c) {
    return (a < b) ? ((a < c) ? a : c) : ((b < c) ? b : c);
}

int main() {
    int a = 3, b = 2, c = 1;
    cout << "Min of " << a << ", " << b << ", " << c << " is " << min(a, b, c) << endl;

    double x = 1.23, y = 2.34, z = 0.99;
    cout << "Min of " << x << ", " << y << ", " << z << " is " << min(x, y, z) << endl;

    return 0;
}
