C Program to Multiply two Floating Point Numbers

In this program, user is asked to enter two numbers (floating point numbers). Then, the product of those two numbers is stored in a variable and displayed on the screen.

To understand this example, you should have the knowledge of following C programming topics:

Program to Multiply Two Numbers

#include <stdio.h>
int main()
{
    double firstNumber, secondNumber, product;
    printf("Enter two numbers: ");

    // Stores two floating point numbers in variable firstNumber and secondNumber respectively
    scanf("%lf %lf", &firstNumber, &secondNumber);  
 
    // Performs multiplication and stores the result in variable productOfTwoNumbers
    product = firstNumber * secondNumber;  

    // Result up to 2 decimal point is displayed using %.2lf
    printf("Product = %.2lf", product);
    
    return 0;
}

Output

Enter two numbers: 2.4
1.12
Product = 2.69

In this program, user is asked to enter two numbers. These two numbers entered by the user is stored in variable firstNumber and secondNumber respectively. This is done using scanf() function.
Then, the product of firstNumber and secondNumber is evaluated and the result is stored in variable productOfTwoNumbers.

Finally, the productOfTwoNumbers is displayed on the screen using printf() function.
Notice that, the result is round to second decimal place using %.2lf conversion character.

C "Hello, World!" Program

C "Hello, World!" Program A simple C program to display "Hello, World!" on the screen. Since, it's a very simple program, it is often used to illustrate the syntax of a programming language. To understand this example, you should have the knowledge of following C programming topics: C Input Output (I/O) Program to Display "Hello, World!" #include <stdio.h> int main () { // printf() displays the string inside quotation printf ( "Hello, World!" ); return 0 ; } Output Hello, World! How "Hello, World!" program works? The #include <stdio.h> is a preprocessor command. This command tells compiler to include the contents of stdio.h (standard input and output) file in the program. The stdio.h file contains functions such as scanf() and print() to take input and display output respectively. If you use printf() function ...

C Program to Find Factorial of a Number Using Recursion

C Program to Find Factorial of a Number Using Recursion Example to find factorial of a non-negative integer (entered by the user) using recursion. To understand this example, you should have the knowledge of following C programming topics: C Programming Functions C User-defined functions C Recursion The factorial of a positive number n is given by: factorial of n (n!) = 1*2*3*4....n The factorial of a negative number doesn't exist. And the factorial of 0 is 1. You will learn to find the factorial of a number using recursion in this example. Visit this page to learn, how you can find the factorial of a number using loop . Example: Factorial of a Number Using Recursion #include <stdio.h> long int multiplyNumbers ( int n ); int main () { int n ; printf ( "Enter a positive integer: " ); scanf ( "%d" , & n ); printf ( "Factorial of %d = %ld...

C Program to Check Leap Year

C Program to Check Leap Year This program checks whether an year (integer) entered by the user is a leap year or not. To understand this example, you should have the knowledge of following C programming topics: C Programming Operators C if...else Statement A leap year is exactly divisible by 4 except for century years (years ending with 00). The century year is a leap year only if it is perfectly divisible by 400. Example: Program to Check Leap Year #include <stdio.h> int main () { int year ; printf ( "Enter a year: " ); scanf ( "%d" ,& year ); if ( year % 4 == 0 ) { if ( year % 100 == 0 ) { // year is divisible by 400, hence the year is a leap year if ( year % 400 == 0 ) printf ( "%d is a leap year." , year ); else printf ( "%d i...
