Question

/* Write a program that asks the user 
* to enter the starting point and end 
* point of the counting range and the 
* increment value and displays the total 
* of the numbers within that range 
*/ 

int start; 
int end; 
int increment; 
int sum = 0; 
int count= 0; 

Console.WriteLine(" Enter the start number ");

Console.WriteLine(" Enter the end number "); 
end = Int32.Parse(Console.ReadLine()); 

Console.WriteLine(" Enter the increment number "); 
increment = Int32.Parse(Console.ReadLine()); 

for (start = ; end <= start ; count = count + increment ) 
{ 

    Console.WriteLine(" Number is: " + count);

あなたがstart < end whileループをしたい、その条件が満たされるたびに、カウンタがincrementによってインクリメントされます。

これはあなたのループの構造を次のようになります。

for (int i = start; i < end; i += increment) 
{ 
    // Add to total and display current value 
}
