C Program to Calculate the Factorial of a number using Function

 C Program to Calculate the Factorial of a number using Function.

    In this example, we will calculate the factorial of a number using function. Here we have used functions with Arguments and return value to perform this operation. We have declared a user-defined function fact which is called in the main function when printing the result.


What is a Factorial of  a Number?
    
The factorial of a number is the product of all positive integers less than, equal to n. Factorial is denoted by the symbol '!'. Formula of factorial is n!=n x (n-1)!

For example:

6!= 6 x 5 x 4 x 3 x 2 x1

   = 720


PROGRAM TO CALCULATE THE FACTORIAL OF A NUMBER USING FUNCTION

#include<stdio.h>
#include<conio.h>
int fact(int);
void main()
{
    int n;
    printf("Enter the number : ");
    scanf("%d",&n);
    printf("Factorial of %d is : %d",n,fact(n));
    getch();
}
int fact(int b)
{
    int i,f=1;
    for(i=1;i<=b;i++)
    {
        f=f*i;
    }
    return(f);
}


OUTPUT OF FACTORIAL OF A NUMBER USING FUNCTION.

  Enter the number : 6

  Factorial of 6 is : 720

C Program to print the PASCAL Triangle up to the Nth row where n is a value inputted by the user

 C Program to print the PASCAL Triangle up to the Nth row where n is a value inputted by the user.  .    In this example, we will print a Pascal's triangle upto to the value of the Nth row entered by the user. In the output section we have taken the value of n as 6 and the pascal's triangle is shown in the output. No, it is not that you have to take the value of n as 6, you can enter any value according to your choice. And the required pascal's tringle will be available on the screen.   What is Pascal's Triangle? Pascal's Triangle is a triangular arrangement of the binaomaial coefficients of the expansion (x+y) n  for positive integral values of n. PROGRAM  TO PRINT THE PASCAL TRIANGLE UP TO THE N-TH ROW WHERE N IS A VALUE INPUTTED BY THE USER: #include <stdio.h> #include <conio.h> void  main() {      int  n,coef=1,space,i,j;     printf( "Enter the value of n:" ); ...

C Program to Check a Whether a Number is Divisible by 5 or Not

 C Program to Check a Whether a Number is Divisible by 5 or Not            In this program we will check a number entered by the user will be divisible by 5 or Not. We have solved this problem using if-else statement. Program: #include <stdio.h> #include <conio.h> int  main() {      int  x;     printf( "Enter a number" );     scanf( "%d" ,&x);      if (x% 5 == 0 )         printf( "The number %d is divisible by 5" ,x);      else         printf( "The number %d is not divisible by 5" ,x);      return   0 ; } Output: NOTE:   You Can Comment Your Code if you have solved differently and we will pin it in the comment section.  Let's Learn toget...

C program to convert a decimal number into binary number using function.

 C program to convert a decimal number into binary number using function.     In this example, we  convert the decimal number entered by the user into binary form. Here, in the out put we have taken a decimal number 20 whose binary  is printed as 10100. You can take other numbers such as 15, 13 78, etc... PROGRAM TO CONVERT A DECIMAL NUMBER INTO BINARY NUMBER USING FUNCTION. #include   <stdio.h> #include <conio.h> int  binary( int   b ); void  main() {      int  b;     printf( "\nEnter the Number You want to convert : " );     scanf( "%d" , &b);     binary(b);     getch(); } int  binary( int   b ) {      int  a[10], i, j;      for  (i = 0;  b  > 0; i++)     ...

C Program to Generate Multiplication Table according to User Choice.

 C Program to Generate Multiplication Table according to User Choice.     In this program, we will learn how to print a multiplication table according to any positive number entered by the user. This program uses for loop to solve this problem.  C PROGRAM TO GENERATE MULTIPLICATION TABLE: # include < stdio.h > # include < conio.h > int   main () {      int   i , num , res = 0 ;      printf ( "\n Enter the multplication table you want :  " );      scanf ( " %d " ,& num );      printf ( "\n\n\n\t MULTIPLICATION TABLE OF  %d \t" , num );      printf ( "\n -------------------------------------------------- \n" );      for ( i = 1 ; i <= 10 ; i ++)      {          res = num * i ;       ...

C Program to Generate and Print Fibonacci series upto a given inputted number

 C Program to Generate and Print Fibonacci series upto a given inputted number     In this example, we will generate and print fibonacci series upto a the upper limit entered by the user. To solve this problem we should have a proper concept on Fibonacci series and while loop.  What is a Fibonacci Series? Fibonacci series is the sum of the two preceding numbers, starting from 0 and 1.     For Example: 0,1,1,2,3,5,8,13,....,etc  PROGRAM #include <stdio.h> #include <conio.h> void   main () {      int   n , x1 , x2 , x3 = 0 ;      printf ( "Enter the limit upto which fibonacci series to be generated : " );      scanf ( " %d " ,& n );      x1 = 0 ;      x2 = 1 ;      printf ( " %d \t %d " , x1 , x2 );      x3 = x1 + x2 ;   ...
