C Program to Multiply two Floating Point Numbers

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.
 
Multiplication of two number
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 Program to Find all Roots of a Quadratic Equation

C Program to Find all Roots of a Quadratic Equation This program accepts coefficients of a quadratic equation from the user and displays the roots (both real and complex roots depending upon the discriminant ).   To understand this example, you should have the knowledge of following C programming topics: C Programming Operators C if...else Statement The standard form of a quadratic equation is: ax 2 + bx + c = 0, where a, b and c are real numbers and a ≠ 0 The term b 2 -4ac is known as the discriminant of a quadratic equation. The discriminant tells the nature of the roots. If discriminant is greater than 0, the roots are real and different. If discriminant is equal to 0, the roots are real and equal. If discriminant is less than 0, the roots are complex and different. Example: Program to Find Roots of a Quadratic Equation #include <stdio.h> #include <math.h> int main () ...

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...

C Program to Find ASCII Value of a Character

C Program to Find ASCII Value of a Character In C programming, a character variable holds ASCII value (an integer number between 0 an 127) rather than character itself. You will learn how to find ASCII value of a character in this program.   To understand this example, you should have the knowledge of following C programming topics: C Programming Data Types C Programming Constants and Variables C Input Output (I/O) A character variable holds ASCII value (an integer number between 0 and 127) rather than that character itself in C programming. That value is known as ASCII value. For example , ASCII value of 'A' is 65. What this means is that, if you assign 'A' to a character variable, 65 is stored in that variable rather than 'A' itself. Program to Print ASCII Value #include <stdio.h> int main () { char c ; printf ( "Enter a character: " ); // Re...
