BASIC 或 C 或 Pseudo code 寫出如下程式

Question

用程式語言如 BASIC 或 C 或 Pseudo code 寫出如下程式, 印出結果

sum=1+2+3+…..+100 (即印出 sum 值)

product=1*2*3*….*10 (即印出 product 值)

及99*法表印出如下

2*1=2

2*2=4

.

.

2*9=18

3*1=3

3*2=6

..

3*9=27

4*1=4

.

9*9=81

最佳解答

//sum(By C++)

#include <iostream>

using namespace std;

int main(void)

{

int sum=0;

for (int i=1;i<101;i++)

sum+=i;

cout<<sum;

getchar();

}

//-----------------------------------------------

//product (By C++)

#include <iostream>

using namespace std;

int main(void)

{

int product=1;

for (int i=1;i<11;i++)

product*=i;

cout<<product;

getchar();

}

//-----------------------------------------------

//99 (By C++)

#include <iostream>

using namespace std;

int main(void)

{

int product=1;

for (int i=2;i<10;i++)

for (int j=1;j<10;j++)

cout<<i<<"*"<<j<<"="<<i*j<<endl;

getchar();

}

//--------------------------

//Sum (By VB)

Dim i As Integer, sum As Integer

sum = 0

For i = 1 To 100

sum = sum + i

Next

Print sum

//--------------------------

//product (By VB)

Dim i As Integer, product As Long

product = 1

For i = 1 To 10

product = product * i

Next

Print product

//--------------------------

//99 (By VB)

Dim i As Integer, j As Long

For i = 2 To 9

For j = 1 To 9

Print i & "*" & j & "=" & i + j
