C_改变字符编码实现简单加密
源码:
# include <stdio.h>
int main()
{
/* 定义字符型变量，并给它们付初值 */
char c1, c2, c3, c4, c5, c6, c7;
c1 = 'C';
c2 = 'h';
c3 = 'i';
c4 = 'n';
c5 = 'e';
c6 = 's';
c7 = 'e';
/* 输出原码 */
printf("原码是：%c%c%c%c%c%c%c\n", c1, c2, c3, c4, c5, c6, c7);
/* 对字符进行译码运算 */
c1 = c1 + 6;
c2 = c2 + 6;
c3 = c3 + 6;
c4 = c4 + 6;
c5 = c5 + 6;
c6 = c6 + 6;
c7 = c7 + 6;
/* 输出译码结果 */
printf("密码是：%c%c%c%c%c%c%c\n", c1, c2, c3, c4, c5, c6, c7);
return 0;
}
