所以這個代碼應該驗證用戶輸入的密碼。密碼必須至少有6個字符,它應該有至少一個大寫字母和至少一個小寫字符,並且至少應該有一個數字。我試圖這樣做,當我運行它,它要求我輸入密碼,但是如果我輸入無效密碼,它不會顯示任何內容。密碼驗證代碼,處理C++ cstrings
#include "stdafx.h"
#include <iostream>
#include <cstring>
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
const int size = 1000;
char password[size];
int count;
int times1 = 0;
int times2 = 0;
int times3 = 0;
cout << "Please enter your password: ";
cin.getline(password,size);
if (strlen(password) < 6){
"Not valid, your password should be atleast 6 letters";
}
for(count = 0; count < strlen(password); count++){
if (isupper(password[count])) {
times1++;
}
if (islower(password[count])){
times2++;
}
if (isdigit(password[count])){
times3++;
}
}
if (times1 == 0) {
"Invalid, the password should contain atleast one uppercase letter";
}
if (times2 == 0) {
"Invalid, the password should contain atleast one lowercase letter";
}
if (times3 == 0) {
"Invalid, the password should contain atleast one digit";
}
cin.get();
return 0;
}
哇...典型的3點錯誤:P haha – user566094
@ user566094,是的,它發生了。 :) –
