除第一行，其他每行的開頭是年份，統計每行的總和，並算出哪年最大。輸出結果應該像下面這樣：Year Sum2008 9952009 9612010 951 （要輸出全部年份）Year of Maximum Regional Offices = 2008Number of Regional Offices = 995

補充：問題的格式不正確 ，應該是像補充裡面的那樣的！
除第一行，其他每行的開頭是年份，統計每行的總和，並算出哪年最大。輸出結果應該像下面這樣：
Year Sum
2008 995
2009 961
2010 951 （要輸出全部年份 1991-2010）
Year of Maximum Regional Offices = 2008
Number of Regional Offices = 995
最佳回答：
#include <stdio.h>
int main()
{
FILE* file;
int year,nums[8],myear,msum=0;
file=fopen("data.txt","r");
if(file)
{
fscanf(file,"Year,USA,Japan,UK,China,Germany,France,Singapore,Netherlands\n");
puts("Year Sum");
while(fscanf(file,"%d,%d,%d,%d,%d,%d,%d,%d,%d\n",
&year,&nums[0],&nums[1],&nums[2],&nums[3],&nums[4],&nums[5],&nums[6],&nums[7])==9)
{
int i,sum=0;
for(i=0;i<8;i++)
sum+=nums[i];
printf("%d %d\n",year,sum);
if(sum>msum)
{
myear=year;
msum=sum;
}
}
if(msum>0)
printf("Year of Maximum Regional Offices = %d\nNumber of Regional Offices = %d\n",myear,msum);
fclose(file);
}
return 0;
}
