How to Write a C Program that Sums Odd Values

In this program, we will show you how to write a simple C program that reads 5 numbers and sums all odd values between them. This program can help you practice some basic concepts of C programming, such as variables, arrays, loops, and conditional statements.

C Program

The program consists of three main steps:

  • Declare and initialize the variables and the array that will store the 5 numbers and the sum of odd values.
  • Use a for loop to read the 5 numbers from the user input and store them in the array. Inside the loop, use an if statement to check if each number is odd and add it to the sum if it is.
  • Print the sum of odd values to the output.

Here is the code for each step:

#include <stdio.h>

int main()

{

    int numbers[5]; // an array to store the 5 numbers

    int sum = 0; // a variable to store the sum of odd values

    printf("Enter 5 numbers:\n");

    for (int i = 0; i < 5; i++) 

    {

        scanf("%d", &numbers[i]); 

        if (numbers[i] % 2 != 0) 

        {

            sum += numbers[i]; 

        }

    }

    printf("The sum of odd values is %d\n", sum); 

    return 0;

}

Output

This will prompt you to enter 5 numbers. For example, if you enter '1', '2', '3', '4', and '5', you will get this output:

Enter 5 numbers:

1

2

3

4

5

The sum of odd values is 9

You can try different inputs and see how the program works.

Explanation

  1. The program starts with including the 'stdio.h' header file, which provides input and output functions such as 'printf' and 'scanf'.
  2. Then, it defines the 'main' function, which is the entry point of the program.
  3. Inside the 'main' function, it declares and initializes two variables: 'numbers' and 'sum'. The variable 'numbers' is an array of 5 integers, which will store the 5 numbers entered by the user. The variable 'sum' is an integer, which will store the sum of odd values among the 5 numbers. It is initialized to 0.
  4. Next, it prints a message to the user to enter 5 numbers, using the 'printf' function.
  5. Then, it uses a for loop to read the 5 numbers from the user input and store them in the array. The loop variable 'i' goes from 0 to 4, which are the indices of the array. Inside the loop, it uses the 'scanf' function to read a number from the user input and store it in the array at the corresponding index. For example, if the user enters 1 as the first number, it will be stored in 'numbers[0]'.
  6. After storing a number in the array, it checks if the number is odd or not. To do this, it uses the modulo operator '%', which returns the remainder of dividing two numbers. For example, '1 % 2' returns 1, which means 1 is odd. If the number is odd, it adds it to the sum using the '+=' operator, which is equivalent to 'sum = sum + number'.
  7. After reading and processing all 5 numbers, it prints the sum of odd values using the 'printf' function.
  8. Finally, it returns 0 from the main function, which indicates that the program has executed successfully.

Conclusion

In this program, we have shown you how to write a C program that reads 5 numbers and sums all odd values between them. This program can help you learn some basic concepts of C programming, such as variables, arrays, loops, and conditional statements. We hope you enjoyed this tutorial and found it useful.

How to Convert Days into Years, Weeks and Days in C

If you are learning C programming, you might have encountered some problems that require you to convert a given number of days into years, weeks and days. For example, how many years, weeks and days are there in 1000 days? How about 3650 days? In this program, I will show you how to write a simple C program that can perform this conversion for any number of days. You will also learn some basic concepts of C programming, such as variables, data types, operators, input/output and comments. C program To convert days into years, weeks and days, we need to follow these steps: Declare four integer variables: 'days', 'years', 'weeks' and 'rem'. Ask the user to enter the number of days and store it in the variable 'days'. Divide the number of days by 365 to get the number of years and store it in the variable 'years'. Find the remainder of the division by 365 to get the remaining days and store it in the variable 'rem'. Divide the remain

Test your knowledge and skills on various topics of C programming by answering multiple choice questions. there are total 15 questions with answers. Each question has four options and only one of them is correct. You can also view the correct answer and explanation for each question at the end of the each question. Good luck and have fun! Q1. What is the advantage of using functions in C language? A) To avoid repetition of code  B) To make the program modular and easy to understand  C) To facilitate code reuse and maintenance  D) All of the above Answer: D) All of the above  Explanation:  Functions are subprograms that can be called from anywhere in the program and carry out a specific task. Functions make programs modular and simple to understand, reduce the need for repetitive code, and make code reuse and maintenance easier. Q2. What is the difference between static and dynamic memory allocation in C language? A) Static memory

How to Add Two Integers in C

If you are learning C programming, you might have encountered some problems that require you to perform some basic arithmetic operations, such as addition, subtraction, multiplication and division. For example, how do you add two integers in C? How do you store and display the result? In this program, I will show you how to write a simple C program that can accept two integers from the user and calculate the sum of the two integers. You will also learn some basic concepts of C programming, such as variables, data types, operators, input/output and comments. C program To add two integers in C, we need to follow these steps: Declare three integer variables: 'a', 'b' and 'sum' . Ask the user to enter the first integer and store it in the variable 'a' . Ask the user to enter the second integer and store it in the variable 'b'. Add the two integers using the '+' operator and store the result in the variable 'sum'. Print the result usi
