Find the Factorial of the numbers

  Here is an example of finding the factorial of any number in the c programming language. code: //how to find the factorials of the numbers #include<stdio.h> int main() { int n = 0;           //variable declare to store the value of user  int fact = 1;           //variable declare to calculate factorials printf("Calculating the factorial of the number entered by the user.\n"); printf("Enter the number:"); scanf("%d", &n); while (n) { fact = fact*n; n--; } printf("\nfact of given number is  %d.\n", fact); getchar; return 0; } In the above code, two int variables fact  and  n.n  is used to store the number of the user wants to find the factorial, which is used to store the value of the factorial. After taking input from the user by the input method, If you do not about the input method visit how to input. While loop used, in the body of the loop multiple the counter n with fact and store in the same variabl

Code: /*This program can correctly print the both triangles till 10 rows.  And in this program all the variable names are appropriate and can be easily understand*/ #include <stdio.h> int factorial(int); //This is factorial function. int main(){ int singlerow = 0; //This variable is for single row. And it will print each row continuously. int noofrows = 0; //This variable is for user input. Means what no of rows want to print? int beforetrianglespaces = 0;                                              //This variable used to print spaces before each line of triangle.  int n = 0;                                                        //As in formula, it is same variable. And it is for rows number.  int k = 0;                                    //As in formula, it is same variable. And it is for each row and it start from 0 and end to number of row which is presently continue. int
