Question

我已经编写了这段代码，但是我得到了＃34;声明被错误地终止了＃34;行错误

int min(int a, int b){..}

以下是我编写的代码

#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
#include <math.h>
#include <string.h>


#define SIZE 10
#define WORD_SIZE 50

void display(node[], int);
void generate_sim_mat(node [], double [][SIZE], int);
int build_cluster(double [][SIZE], int );

int min(int a, int b)

}

我无法调试此问题。有人能告诉我错误在哪里吗？

如果您要在Windows下进行编译，则应注意windef.h（由windows.h包含）将min和max定义为宏。您可以在包含这些文件之前定义NOMINMAX来阻止这种情况，例如：

#define NOMINMAX

或者您可以简单地使用min以外的其他函数名称。

如果您在Windows上不，可能仍然在某处定义min，在这种情况下您应该获取预处理器输出以查看位置，例如gcc -E ...。

声明在c中未正确终止
