C Program to Demonstrate the Working of Keyword long

C Program to Demonstrate the Working of Keyword long

The long is a size modifier, indicated by keyword long, that may increase the size of a variable during declaration. This program will demonstrate the working of long keyword.
 
long keyword in C programming
To understand this example, you should have the knowledge of following C programming topics:

Example: Program to Demonstrate the Working of long

#include <stdio.h>
int main()
{
    int a;
    long b;
    long long c;

    double e;
    long double f;


    printf("Size of int = %ld bytes \n", sizeof(a));
    printf("Size of long = %ld bytes\n", sizeof(b));
    printf("Size of long long = %ld bytes\n", sizeof(c));

    printf("Size of double = %ld bytes\n", sizeof(e));
    printf("Size of long double = %ld bytes\n", sizeof(f));

    return 0;
}
Output
Size of int = 4 bytes 
Size of long = 8 bytes
Size of long long = 8 bytes
Size of double = 8 bytes
Size of long double = 16 bytes
In this program, the sizeof operator is used to find the size of int, long, long long, double and long double.
The long keyword cannot be used with float and char type variables.

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 Add Two Integers

C Program to Add Two Integers In this program, user is asked to enter two integers. Then, the sum of those two integers is stored in a variable and displayed on the screen.   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) C Programming Operators Program to Add Two Integers #include <stdio.h> int main () { int firstNumber , secondNumber , sumOfTwoNumbers ; printf ( "Enter two integers: " ); // Two integers entered by user is stored using scanf() function scanf ( "%d %d" , & firstNumber , & secondNumber ); // sum of two numbers in stored in variable sumOfTwoNumbers sumOfTwoNumbers = firstNumber + secondNumber ; // Displays sum printf ( "%d + %d = %d" , firstNumber , secondNum...

C Program to Find Factorial of a Number

C Program to Find Factorial of a Number The factorial of a positive integer n is equal to 1*2*3*...n. You will learn to calculate the factorial of a number using for loop in this example. To understand this example, you should have the knowledge of following C programming topics: C Programming Data Types C Programming Operators C if...else Statement C Programming for Loop 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, 0! = 1 Example: Factorial of a Number #include <stdio.h> int main () { int n , i ; unsigned long long factorial = 1 ; printf ( "Enter an integer: " ); scanf ( "%d" ,& n ); // show error if the user enters a negative integer if ( n < 0 ) printf ( "Error! Factorial of a negative number doesn't exist." ); else ...
