C语言编程:输入某年某月某日判断这一天是一年的第几天的程序是是什么? #include返回指定年月日是对应年度的第几天int getDays(int month,int day);int isRunnian(int year);int main(int argc,char*argv[]){int year=0;int month=0;int day=0;printf(\"请输入年月日格式示例20140101\\n\");scanf(\"%4d%2d%2d\",&year,&month,&day);简化后的条件,是闰年且月份大于二,则返回天数加一,否则直接返回函数值int days=getDays(month,day);if(days=0){printf(\"您输入的日期格式无效。\\n\");return 0;}if(isRunnian(year)&month>;2){printf(\"输入日期是对应年份的第%d天\",days+1);}else{printf(\"输入日期是对应年份的第%d天\",days);}return 0;}循环实现int getDays(int month,int day){int NUMBER[12]={31,28,31,30,31,30,31,31,30,31,30,31};int result=day;if(month>;12){/避免出现数组越界情况return 0;}for(int i=0;i;i+){/数组下标是从零开始result+NUMBER[i];}return result;}int isRunnian(int year){闰年的条件一:年度是400的整数倍,则是闰年二:年度能被4整除且不能被100整除return year%4=0&year%100。0|year%400=0;}

输入某年某月某日,判断输入天是这一年的第几天,c语言,先编一个函数,从主函数中调用 #includeint date(int year,int month,int day){ int a[]={31,28,31,30,31,30,31,31,30,31,30,31};int sum=0;int i;if(((year%4=0)&(year%100。0))|(year%400=0))sum+;for(i=0;i;i+)sum=sum+a[i];return sum+day;}int main(){ int year=0,month=0,day=0,n=0;printf(\"input year:\\n\");scanf(\"%d\",&year);printf(\"input month:\\n\");scanf(\"%d\",&month);printf(\"input day:\\n\");scanf(\"%d\",&day);n=date(year,month,day);printf(\"%d年%d月%d号是今年第%d天\\n\",year,month,day,n);return 0;}在vc环境下 已测试运行成功

c语言题目:输入某年某月某日,判断这一天是这一年的第几天? include/*此头函数请不要删除*/include int main(){ int days[]={0,31,28,31,30,31,30,31,31,30,31,30,31};int i,j,k,y,m,d,b,n,sum;while(scanf(\"%d/d/d\",&y,&m,&d)。。
