[問題] 陣列輸入東西後 剩下空的想要變成空白
開發平台(Platform): (Ex: VC++, GCC, Linux, ...)
C++
額外使用到的函數庫(Library Used): (Ex: OpenGL, ...)
無
問題(Question)：
如何將數值輸入後將後面的東西變成空白
EX:a[10]
輸入:kkaaee
要將a[6]~a[8]變成空白
錯誤結果(Wrong Output)：
儲存的東西會變成亂碼
程式碼(Code)：(請善用置底文網頁, 記得排版)
#include<iostream>
#include<string.h>
using namespace std;
int main(){
char password[10]; //宣告陣列password
cout<<"set your password\n"; //顯示設定密碼
cin.getline(password,10); //設定密碼
cout<<"password is "<<password<<endl; //顯示儲存的密碼
for(i=strlen(password) ; i<=9 ; i++){
password[i]=' ';
}
cout<<password<<"\n";
return 0;
}
