说明

最近工作需要固定写死好几个随机码，自己想的又不够随机，所以搞了个随机码生成器[10位字母+数字]

rand10bit.cpp

#include "rand10bit.h"#include "ui_rand10bit.h"#include"time.h"Rand10Bit::Rand10Bit(QWidget *parent) :QWidget(parent),ui(new Ui::Rand10Bit){ui->setupUi(this);this->setWindowTitle(QString::fromUtf8("10位字母+数值"));// 对Label可复制ui->rand10bitLabel->setTextInteractionFlags(Qt::TextSelectableByMouse);}Rand10Bit::~Rand10Bit(){delete ui;}void Rand10Bit::on_createBtn_clicked(){char chr[]={'0','1','2','3','4','5','6','7','8','9','0','A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'};srand((unsigned int)time(NULL));QString tempstring;char buf[10]={0};int idx=0;for(int i=0;i<10;i++){idx=rand()%62;//chr[0-61]//sprintf_s(buf,"%c",chr[idx]);sprintf(buf,"%c",chr[idx]);tempstring.append(buf);if(7==i)//确保有数值{QRegExp regexp("[a-zA-Z]+[0-9]+");// 字母+数值if(regexp.exactMatch(tempstring)==false){idx=rand()%10;//0-9sprintf(buf,"%c",chr[idx]);tempstring.append(buf);idx=rand()%52+10;//10-61sprintf(buf,"%c",chr[idx]);tempstring.append(buf);break;}}}ui->rand10bitLabel->setText(tempstring);}
