您的答案為: 3.000000x10(1 ...略 正確答案為: 3x10(10) 

xxxxx幫忙測一下程式碼......我實在找不到錯誤......xxxxx

 

// d451.cpp

// 科學記號

#include <iostream>

#include <iomanip>

#include <math.h>

using namespace std;

int main()

{

long double n[100];

int line(0);

int count(0);

int ten(0);

double bits(0);

while(cin >> line)

{

for(count = 0; count < line; count++)

{

cin >> n[count] >> bits;

while(n[count] < 1)

{

n[count] = n[count]*10;

ten = ten - 1;

}

while(n[count] >= 10)

{

n[count] = n[count]/10;

ten = ten + 1;

}

cout << fixed << setprecision(bits-1) << n[count]; 

cout << "x10(" << ten << ")";

cout << endl;

ten = 0;

bits = 0;

}

line = 0;

}

return 0;

}
