推荐答案

当您使用 scanf 时，%c 旨在获取单个字符.如果要获取字符串，需要使用%s.

when you use scanf, %c is intended to get a single character. If you want to get a string, you need to use %s.

此外，在 C 语言中，字符串只是字符数组.所以需要声明一个char数组.

Also, in C langage, string are just char arrays. So you need to declare a char array.

#include <stdio.h>

int main ()
{
   char yourname[100];
   int yourage;

   printf("Whats your name?\t");
   scanf("%s",yourname); //i let you read the doc to avoid overflow :)
   printf("How old are you?\t");
   scanf("%d",&yourage);
   printf("You are %d years old and your name is %s \n\n\n",yourage,yourname);
   system("pause");
   return(0);
}
