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; // Declare variables for user input and calculations
    printf("\nInput a pair of numbers (for example 10,2):");
    printf("\nInput first number of the pair: ");
    scanf("%d", &x); // Read the first number
    printf("\nInput second number of the pair: ");
    scanf("%d", &y); // Read the second number

    if (x < y) {
        return 0; // If x is less than y, exit the program
    }

    printf("\nList of odd numbers: ");
    for (i = y; i <= x; i++) {        
        if ((i % 2) != 0) {
            printf("%d\n", i); // Print odd numbers within the range
            total += i; // Add odd numbers to the total
        }
    }
    
    printf("Sum=%d\n", total); // Print the total sum

    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
