前几天，同宿舍的一位同事要为一年365天每天创建一个文件夹，并且文件夹以当天的日期命名，比如1月1日对应的文件夹为0101，1月2日对应的则为0102......。
上学的时候，因为程序设计的需要，用C语音创建过文件夹，所以决定送他一程，程序如下：#include <stdio.h>
#include <conio.h>
#include <process.h>
#include <dir.h>
#include <string.h>
void main(){
int i=0,j=0,counter=0;
char fname[5];
char month[12][3]={
"01",
"02",
"03",
"04",
"05",
"06",
"07",
"08",
"09",
"10",
"11",
"12"
};
char date[31][3]={
"01",
"02",
"03",
"04",
"05",
"06",
"07",
"08",
"09",
"10",
"11",
"12",
"13",
"14",
"15",
"16",
"17",
"18",
"19",
"20",
"21",
"22",
"23",
"24",
"25",
"26",
"27",
"28",
"29",
"30",
"31"
};
char a[20]="mkdir ";
system("mkdir helloword");
system("cd helloword");
for (i=1;i<=12;i++){
strcpy(fname,month[i-1]);
/* switch(i){
case 2:
counter=28;
break;
case 4:
case 6:
case 9:
case 11:
counter=30;
break;
default:
counter=31;
break;
}*/
if(i==2){
counter=28;
}
else if (i==4||i==6||i==9||i==11){
counter=30;
}
else{
counter=31;
}
for(j=0;j<counter;j++){
printf("i=%d,j=%d\n",i,j);
fname[0]='\0';
a[6]='\0';
strcpy(fname,month[i-1]);
strcat(fname,date[j]);
strcat(a,fname);
system(a);
}
}
getch();
}
