sscanf函数和sprintf函数的用法

#include<stdio.h>#include<string.h>int main(){int n,i;char a[1000];while(scanf("%d",&n)==1){int t;sprintf(a,"%d",n);          //把整型数转化为字符型int len=strlen(a);sscanf(a,"%d",&t);          //把字符型的转化为整型for(i=0;i<len;i++)printf("%c ",a[i]);printf("\n");          //输出字符型的数字printf("%d\n",t);      //输出整型的数字}return 0;}
