大家好，今日琪琪来为大家解答以上的问题。16进制在线计算器，16进制对照表很多人还不知道，现在让我们一起来看看吧！

1、16进制转换成2进制很简单的,自己慢慢写吧...16进制的1位对应2进制的4位...用8421码,,,也就是8421码 8421码1=0001 9=10012=0010 A=10103=0011 B=10114=0100 C=11005=0101 D=11016=0110 E=11107=0111 F=11118=1000写的这么清楚会对应的吧,,,在长都不怕,,也不会出错比如:16进制的 A5121=1010 1001 0001 0010 0001;0110001111010111101100010111110001101111010101011001010101101010011000000101101100110110011000010000010101000011000100111101111010111100001101110011110011010110001110000110011000011110011010100000010110001001011011011111111001110010011111111011000010100101谢了个小程序，把你给的十六进制数转成二进制存到了c盘根目录下的FILE.txt文件中了。

2、#include#include void main(){char str[100]="63d7b17c6f55956a605b3661054313debc373cd638661e6a05896dfe727fb0a5";int i;FILE fp;fp=fopen("c:file.txt","w");for(i=0;iswitch(str[i]){case '0':fprintf(fp,"0000");break;case '1':fprintf(fp,"0001");break;case '2':fprintf(fp,"0010");break;case '3':fprintf(fp,"0011");break;case '4':fprintf(fp,"0100");break;case '5':fprintf(fp,"0101");break;case '6':fprintf(fp,"0110");break;case '7':fprintf(fp,"0111");break;case '8':fprintf(fp,"1000");break;case '9':fprintf(fp,"1001");break;case 'a':fprintf(fp,"1010");break;case 'b':fprintf(fp,"1011");break;case 'c':fprintf(fp,"1100");break;case 'd':fprintf(fp,"1101");break;case 'e':fprintf(fp,"1110");break;case 'f':fprintf(fp,"1111");break;}fclose(fp);}。
