UM程式研究日誌

這次寫得很糊塗有點亂 最後一題很奇怪 ...回來之後小改一下0.0發現...(?)

那麼來了喔!

#include 
using namespace std;
int main(){
	
	cout<<"Enter the number of values to be summed follow by the values"<<endl;
	int count; //輸入的數值個數 
	double i;//輸入的數值 
	double sum=0;//總合 
	
	cin>>count;	
	
	for(count;count>=1;count--)
	{
		cin>>i;
		sum+=i;
	}
	cout<<"Sum of the values is "<<sum<<endl;
}

	for(i=0;;i++)
	
	{
	
	cin>>num;
		if(num==9999)

#include 
using namespace std;

int main(){
	
	
	double m=1;//分母 
	int f=1;//正負號 
	double num=4/1;
	double sum=0; 
	double i; 
	
	for(i=1;i<=1000;i++)
	{
		
		num = (4/m);
		sum += (f)*(num);
		m+=2;
		f*=-1;
		cout<<"第"<<i<<"個"<<sum<<endl;		
	}
	
		
} 

 再做第5題時怎麼試算出來都是帶有負號的-3.14159檢查時免強用加負號讓答案變正過關

回家看時才發現他第一項是"正的" 我一開始原本f是用負號 現在改回來了 ...覺得
