手動(dòng)轉(zhuǎn)換的方法書上很詳細(xì)，給你份代碼

#include<stdio.h>
int?main()
{
????char?ku[16]={'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'};
????int?zh[32],i=0,w,j;
????long?int?b,y;
????printf("請(qǐng)輸入一個(gè)十進(jìn)制數(shù)，我能幫您把它轉(zhuǎn)換成2~16任意進(jìn)制數(shù)：\n");
????scanf("%d",&y);
????b=y;
????printf("請(qǐng)輸入要轉(zhuǎn)換為的進(jìn)制:");
????scanf("%d",&w);
????printf("\n");
????do
????{
????????zh[i]=y%w;
????????i++;
????????y=y/w;
????}
????while(y!=0);
????printf("把十進(jìn)制的%ld轉(zhuǎn)換為%d進(jìn)制:",b,w);
????for(i--;i>=0;i--)
????{
????????j=zh[i];
????????printf("%c",ku[j]);
????}
????printf("\n");
????return?0;
}
