不解释
代码:
#include <iostream> #include <cstdio> #include <cstring> using namespace std; char str[5005]; char des[24]; char tran(char c) { char ch=c; if ('a'<=c&&c<='z') { ch=c-'a'+'A'; } else if ('A'<=c&&c<='Z') { ch=c-'A'+'a'; } return ch; } int main() { while (gets(str+1)) { int a=0; int len=strlen(str+1); int lim=len/16; int mark=len%16; for (int k=1;k<=lim;k++)//先处理前面为整16字符的 { printf("%04x: ",a+(k-1)*16); int j=1; for (int i=(k-1)*16+1;i<=(k-1)*16+16;i++) { printf("%x",str[i]); if (!(i&1))printf(" "); des[j++]=tran(str[i]); if (i%16==0) { printf("%s\n",des+1); } } } if (mark==0)continue; printf("%04x: ",a+lim*16);//向下为处理后面剩余的字符(不足16个) int l=1; int i; for (i=lim*16+1;str[i]!='\0';++i) { printf("%x",str[i]); des[l++]=tran(str[i]); if (!(i&1))printf(" "); } des[l]='\0'; for (int j=i;j<=lim*16+16;++j) { printf(" "); if (!(j&1))printf(" "); } printf("%s\n",des+1); } return 0; }
