Over No. 1 二、算法设计 1、十六进制转换成十进制数:写一个函数，输入一个十六进制数，输出相应的十进制数。 (1)把输入的十六进制数看成一个数组(char s[N])，十六进制各个位的字符代为相应数组的元素(s[i])。 (2)写出主函数通过调用将十六进制数转为十进制数的函数(fun)，实现将十六进制数转为十进制数。 (3)程序图如下图1 开始 输入十六进制数字符串s[N] S[i]是否大于10 t=s[i]-‘a’+10 t=s[i]-‘0’ sum=sum*16+t i=0,i++ i<=N? 输出十进制结果sum 结束 程序1 三、编程实现 程序的具体C语言代码如下: feel free to listen to their voices and help the masses solve problems, we were officially opened on May 10 "12345" Mayor calls, formulated rules and regulations, equipped with a full-time staff, a 24-hour on-duty system, people to call to receive, reply, action, reminders, feedback and so on.
