sprintf和sscanf的使用

#define _CRT_SECURE_NO_WARNINGS
#include<stdio.h>

struct stu {
  int age;
  char name[1024];
};
int main() {
  struct stu st = { 25,"LiMing" };
  struct stu st1 = { 0 };
  char arr[1024] = { 0 };
  //整合到一起
  sprintf(arr, "%d %s", st.age, st.name);
  //统一输出
  printf(arr);
  printf("\n");
  //把整合到一起的arr拆散开，放到同样的结构体st1中
  sscanf(arr,"%d %s",&(st1.age),st1.name);
  printf("%d %s", st1.age, st1.name);

  return 0;
