十進位制的轉換

#include

int main (
void);
int convertednumber[64]
;long
int numbertoconvert;
int nextdigit, base, index =0;
// get the number and the base
printf (
"number to be converted? ");
scanf (
"%ld"
,&numbertoconvert)
;printf (
"base? ");
scanf (
"%i"
,&base)
;// convert to the indicated base
dowhile
( numbertoconvert !=0)
;// display the results in reverse order
printf (
"converted number = ");
for(
--index; index >=0;
--index )
printf (
"\n");
return0;
}

number to be converted? 10

base? 2

converted number = 1010

program 7.7 output (rerun)

number to be converted? 128362

base? 16

converted number = 1f56a

1.取餘數，放進陣列，但為逆序

2. 建立乙個字元陣列16位，放進16base所有數字對應的字母

3.逆序輸出時，令nextdigit等於陣列中的乙個餘數，對應字元陣列的字元輸出即可。

4.對base應該有個判斷：若base為零則run time error；base=1則進入無限迴圈；base超過16則要擴充套件陣列16.
