标签:

描述:    给定两个合法的时间(格式固定:hh:mm:ss,时间合法,不用考虑其它情况),输入两个时间相加后的结果;注意,相加后的结果也必需是一个合法的时间;
附合法时间定义:小时在[00-23]之间,分钟和秒分别是在[00-59]之间;
运行时间限制:    无限制
内存限制:    无限制
输入:    时分秒格式的时间字符串,如00:00:00
输出:    时分秒格式的时间字符串,如00:00:00

样例输入:    00:00:00 00:00:01
样例输出:    00:00:01
答案提示:    建议将时间转换为秒数计算

 

//定义一个时间结构

typedef struct
{
  int hh, mm, ss;
}Time;

 

int testTime(Time *t)
{
  if (t->hh>23 || t->hh<0 || t->mm>59 || t->mm<0 || t->ss>59 || t->ss<0)
  {
    if (t->hh==24)
    {
      if (t->mm==0 || t->ss==0)
      {
        return 0;
      }
    }
    return -1;
   }else
  return 0;
}

void addTime(Time t1, Time t2, Time *output)
{
  int time1 = t1.hh*60*60 +t1.mm*60 +t1.ss;
  int time2 = t2.hh*60*60 +t2.mm*60 +t2.ss;
  int time = time1+time2;
  double result;

  Time* resultTime = (Time *)malloc(sizeof(Time));
  resultTime->hh = time / (60*60);

  time %= (60*60);
  resultTime->mm = time / 60;
  time %= 60;
  resultTime->ss = time;

  result = testTime(resultTime);
  if(result == -1)
  {
    resultTime->hh -= 24;
  }
  output->hh = resultTime->hh;
  output->mm = resultTime->mm;
  output->ss = resultTime->ss;
}


 

int charToInt(char *ch){
int len = strlen(ch);
int k =10;
int sum = 0;
for(int i = 0; i < len ; ++i){
sum = sum * k + (ch[i] - ‘0‘);
}
return sum;
}

int k = 0;
int sum =0;
char b[3][3];
for(int i = 0; i < len ; ++i){
if(ch[i] <= ‘9‘ && ch[i] >= ‘0‘ ){
b[count][k] = ch[i];
k++;
}else{
b[count][k] = ‘\0‘;
++count;
k = 0;
}
}
b[count][k] = ‘\0‘;
sum = charToInt(b[0]) * 60 * 60 + charToInt(b[1]) * 60 + charToInt(b[2]);
delete b;
return sum;
}


int main(){
char* ch1 = "23:12:56";
char* ch2 = "23:12:56";
//countM(ch);
int number1 = countM(ch1);
int number2 = countM(ch2);
int sum = number1 + number2;
int h = 0 , m = 0, s = 0;
s = sum % 60;
m = (sum / 60) % 60;
h = (sum / 60 /60)%24 % 60;
char ch[255];
if(h < 10){
cout<<"0"<<h;
}else{
cout<<h;
}
cout<<":";
if(m < 10){
cout<<"0"<<m;
}else{
cout<<m;
}
cout<<":";
if(s < 10){
cout<<"0"<<s;
}else{

}
