1、公司技术部接到一个任务,需要使用a-z、0-9组成3位的字符密码,现请你设计一个算法,将可能的密码组合全部打印出来。(10分)
#include<stdio.h>
#include<stdlib.h>
void main()
{
//cout<<midnum(a,b,0,1,0,1)<<endl;
FILE *fp=fopen("test.txt","w");
for(int i=0;i<36;i++)
for(int j=0;j<36;j++)
{
for(int k=0;k<36;k++)
{
if(i>=0&&i<=9)
fprintf(fp,"%d",i);
else
fprintf(fp,"%c",i+87);
if(j>=0&&j<=9)
fprintf(fp,"%d",j);
else
fprintf(fp,"%c",j+87);
if(k>=0&&k<=9)
fprintf(fp,"%d ",k);
else
fprintf(fp,"%c ",k+87);
}
fprintf(fp,"\n");
}
fclose(fp);
}
2、请实现字符串反转函数。
void myreverse(char *str)
{
char *p,*q;
p=str;
while(*p)
q=p++;
p=str;
while(p<q)
{
char t=*p;
*p++=*q;
*q--=t;
}
}
void main()
{
char str[]="yanzhengfei";
cout<<str<<endl;
myreverse(str);
cout<<str<<endl;
}
