C Exercises: Compute the sum of consecutive odd numbers from a given pair of integers

C Basic Declarations and Expressions: Exercise-34 with Solution

Write a C program to compute the sum of consecutive odd numbers from a given pair of integers.

Sample Solution:

C Code:

#include <stdio.h>
int main()
  {
	int x, y, i, total = 0;
              printf("\nInput a pair of numbers (for example 10,2):");
	printf("\nInput first number of the pair: ");
	scanf("%d", &x);
             printf("\nInput second number of the pair: ");
	scanf("%d", &y);
	if (x<y)
	{
		return 0;
	}
	printf("\nList of odd numbers: ");
	for(i = y; i<=x; i++)
	{		
	  if ((i%2) != 0)
	  {
		printf("%d\n", i);
		total += i;
		
	   }	
    }
	
	printf("Sum=%d\n", total);

	return 0;
}

Sample Output:

Input a pair of numbers (for example 10,2):                                                          
Input first number of the pair: 10                                                                   
                                                                                                     
Input second number of the pair: 2                                                                   
                                                                                                     
List of odd numbers: 3                                                                               
5                                                                                                    
7                                                                                                    
9                                                                                                    
Sum=24
