我无法编译程序。我的函数参数有什么问题吗？是因为我的数组声明（char类[SIZE] [15]）？由于列部分保持字母表的大小，因此我将其设为2D数组。你们可以指出我的代码有什么问题，以及如何将数组作为函数参数传递？对不起，我对这个话题非常陌生。

您没有以正确的方式将2D数组传递给函数。阅读this topic了解更多详情。顺便说一下，这里是你的代码有一些修改：
#include<iostream>
#include<string.h>
using namespace std;
const int COLSIZE=3;
const int NAMESIZE=30;

void displayPersonalData(int,long[],char[],float[],float[],float[],char[][15]);
void inputCal(int,char[],long[],float[][COLSIZE],char[][10]);
int main()
{
int SIZE;
long ID[SIZE];
char name[NAMESIZE];
float weight[SIZE];

}
}
}
void displayPersonalData(int rowSize,long id[],char nama[],float berat[],float tinggi[],float bmi[],char category[][15])
{
cout<<"No.\tID\tName\t\t\tWeight(kg)\tHeight(m)\tBMI\tCategory\n";
for(int m=0;m<rowSize;m++)
{
cout<<m+1<<"\t"<<id[m]<<"\t"<<nama[m]<<"\t"<<berat[m]<<"\t"<<tinggi[m]<<"\t"<<bmi[m]<<"\t"<<category[m]<<endl;
