利用ascii码加密字符串

#include <stdio.h>

int main()

{
  char c1,c2,c3,c4,c5;
  c1=‘C‘;
  c2=‘h‘;
  c3=‘i‘;
  c4=‘n‘;
  c5=‘a‘;
  c1+=4;  //将c1的字符转换为ascii码加上4再赋给c1本身
  c2+=4;  //将c2的字符转换为ascii码加上4再赋给c2本身
  c3+=4;  //将c3的字符转换为ascii码加上4再赋给c3本身
  c4+=4;  //将c4的字符转换为ascii码加上4再赋给c4本身
  c5+=4;  //将c5的字符转换为ascii码加上4再赋给c5本身
  putchar(c1);
  putchar(c2);
  putchar(c3);
  putchar(c4);
  putchar(c5);
  printf("\n%c%c%c%c%c\n",c1,c2,c3,c4,c5);
  return 0;
