How to Write a C Program That Checks Whether Two Integers Are Multiples

In this program, we will show you how to write a simple C program that reads two integers from the user input and checks whether they are multiples or not. What Are Multiples? Multiples are numbers that can be divided by another number without leaving a remainder. For example, 12 is a multiple of 3 because 12 / 3 = 4 with no remainder. Similarly, 15 is a multiple of 5 because 15 / 5 = 3 with no remainder. To check whether two integers are multiples, we can use the modulo operator (%) . The modulo operator returns the remainder of the division of two numbers. For example, 12 % 3 = 0 and 15 % 5 = 0. If the remainder is zero, it means that the two numbers are multiples. Otherwise, they are not. C Program To write the C program that checks whether two integers are multiples, we need to follow these steps: Include the stdio.h header file that provides input/output functions. Declare two integer variables to store the user input. Print a message to prompt the user to enter two integers. Use

Quiz on Features of C

 C Programming Quiz Welcome to the C programming quiz. 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 Write a C Program to Check if Three Values Can Form a Triangle

In this program, you will learn how to write a C program that reads three floating-point values and checks if it is possible to make a triangle with them . You will also learn how to determine the perimeter of the triangle if the given values are valid. What is a Triangle? A triangle is a polygon with three sides and three angles. The sum of the angles of a triangle is always 180 degrees. The length of each side of a triangle can vary, but there is a condition that must be satisfied for any three values to form a valid triangle. This condition is called the triangle inequality theorem . What is the Triangle Inequality Theorem? The triangle inequality theorem states that for any three values a, b, and c, they can form a valid triangle only if the following inequalities hold: a + b > c b + c > a c + a > b These inequalities mean that the sum of any two sides of a triangle must be greater than the third side. This ensures that the sides can meet at the vertices and form a closed

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 !

How to Write a C Program to Check the Range of an Integer

In this program, we will show you how to write a C program that can read an integer from the user and check the specified range to which it belongs. We will also explain the logic behind the program and how to test it with some sample inputs. C Program The program we are going to write is as follows: #include <stdio.h> int main() {     int num;     printf("Enter an integer: ");     scanf("%d", &num);     if (num < 0 || num > 80)     {         printf("Error: number is out of range.\n");     }     else if (num >= 0 && num <= 20)     {         printf("Number is in the range [0, 20].\n");     }     else if (num >= 21 && num <= 40)     {         printf("Number is in the range [21, 40].\n");     }     else if (num >= 41 && num <= 60)     {         printf("Number is in the range [41, 60].\n");     }     else if (num >= 61 && num <= 80)     {         printf("

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

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
