编写一个程序,实现一个整数,长整数,浮点数,双精度数 除2的计算,要求所有类型的数除2只使用一个函数

用函数模板实现；
#include<stdio.h>
template<typename M>
M Top(M A)
{
return A/2;
}
void main()
{int a=100,long b=200,float c=300.1,double d=400.1;
a= Top(a);
b= Top(b);
c= Top(c);
d= Top(d);
……
……
}

能否 写的具体点 基础点  谢谢

用C的方式写
void fun(void *arg, int flag)
{
    int *p0;
    long int *p1;
    float *p2;
    double *p3;
    switch(flag)
    {
    case 0:
        p0 = (int *)arg;
        *p0 /= 2;
        break;
    case 1:
        p1 = (long int *)arg;
        *p1 /= 2;
        break;
    case 2:
        p2 = (float *)arg;
        *p2 /= 2;
        break;
    case 3:
        p3 = (double *)arg;
        *p3 /= 2;
        break;
    default:
        printf("type flag error!\n");
    }
    return ;
}

看不懂本人是初学者 谢谢

#include <stdio.h>
void computer(void *arg, int flag)
{
    int*p1;
    long int *p2;
    float *p3;
    double *p4;
    switch(flag)
    {
    case 1:
        p1 = (int *)arg;
        printf ("*p1/2=\n",*p1/2);
        break;
    case 2:
        p2 = (long int *)arg;
        printf ("*p2/2=ld\n",*p2/2);
        break;
    case 3:
        p3 = (float *)arg;
        printf ("*p3/2=%f\n",*p3/2);
       break;
    case 4:
        p4 = (double *)arg;
        printf ("*p4/2=%f\n",*p4/2);
        break;
    default:
    printf("input flag error!\n");
    }
    return ;
}
main()
{
    int a =12;
    float b=2.05;
    long int c=(1<<15-1);
    clrscr();
    computer((void *)&a,1);
    computer((void *)&b,3);
    computer((void *)&c,2);
}

我正在学C语言！还望以后多交流！

hehe...还是高手行啊！佩服

高手就是不一样
