7-2 然后是几点 (15分)

要设置很多变量就是取名字有点麻烦，题不是难题，各种if else就可以做，逻辑清晰的话很快就能AC

#include <stdio.h>

int main(){
  int originTime,addTime,curTime;
  scanf("%d %d",&originTime,&addTime);
  int addh = addTime/60;
  int addf = addTime%60;
  int i=0;
  int orih = originTime/100,orif = originTime%100;
  int a,b;//a是最后的小时，b是分钟
  if(orif+addf>=0){
 	 b = (orif+addf)%60;
 	 a = (orif+addf)/60+orih+addh;
  }else{
   b = 60+(orif+addf)%60;
   a = (orif+addf)/60+orih+addh-1;
  }
  printf("%d%02d",a,b);
}
