[問題] printf
( *[1m *[m 為色碼，可以按 Ctrl+V 預覽會顯示的顏色 )
( 未必需要依照此格式，文章條理清楚即可 )
遇到的問題： (題意請描述清楚)
關於printf 要算1的三次方加到X的三次方 範圍由一到50000
希望得到的正確結果：
程式跑出來的錯誤結果：
輸入50000顯示的答案部隊
開發平台： (例: VC++ or gcc/g++ or Dev-C++, Windows or Linux)
dev c
有問題的code： (請善用置底文標色功能)
#include<stdio.h>
main(){
long long unsigned input=0;
long long unsigned sum=0,n;
while(scanf("%llu",&input)==1){
if(input<1 || input>50000){
break;
}
sum = (input*input*(input+1)*(input+1))/4;
printf("%llu\n",sum);
}
return 0;
}
補充說明：
%llu是網路上查到的 應該是long long unsigned 但輸入50000時還是會出錯
我50000 跑出來是3306776128
49999 跑出來是4034958912
