#include <stdio.h>

int main (void)
{
    char address, name;
   
    printf ("Please enter a address.\n");
    scanf ("%c", address);
    printf ("Please enter your name.\n");
    scanf ("%c", name);
    printf ("Your address is %c,your name is %c", address, name);
   
    return 0;
 }

结果：

#include <stdio.h>

int main (void)
{
    char address[40], name[40];
   
    printf ("Please enter a address.\n");
    scanf ("%s", address);
    printf ("Please enter your name.\n");
    scanf ("%s", name);
    printf ("Your address is %s,your name is %s", address, name);
   
    return 0;
 }

scanf后面的参数要是一个地址  老生常谈了  

谢谢 好久没看现在才看到
