Question

Write an algorithm and draw flowchart to add even numbers between 0 and any positive integer number given by the user

Answer 1

// Add even numbers from F to L 
  
//   F =  First number in our range  
//   L =  Last number in our range  
// Sum =  Sum of Even Integers 0-L 
 
F = 0 
  
Input L  // Last number in our range (must be positive integer) 
 
Sum = 0  // Initialize sum of even numbers F-L 
 
N = F    // Initialize 1st number to evaluate 
  
do {  
  
  if ((N % 2) = 0) {  
  
    // N is an even number. Add N to Sum  
    Add N to Sum 
  }  
  
  Add 1 to N  // Go to next number  
  
  // If N > L no more numbers to print  
} while (N <= L) 
 
Print Sum
