- using namespace std;
- int main()
- int i,n;
- cout<<"Enter any number:";
- cin>>n;
- for(i=1;i<=10;++i)
- cout<<" "<<n<<" * "<<i<<" = "<<n*i;
- return 0;

Similarly, it is asked, how do you write a factorial in C++?

- #include <iostream>
- using namespace std;
- int main()
- {
- int i,fact=1,number;
- cout<<"Enter any Number: ";
- cin>>number;
- for(i=1;i<=number;i++){

Also Know, what is do while in CPP?

- The body of the loop is executed at first.
- If the condition evaluates to true , the body of the loop inside the do statement is executed again.
- The condition is evaluated once again.
- If the condition evaluates to true , the body of the loop inside the do statement is executed again.

How do you make a multiplication table in C++?

- #include<iostream>
- using namespace std;
- int main()
- {
- int num;
- cout<<"Enter Number To Find
**Multiplication table**"; - cin>>num;
- for(int a=1;a<=10;a++)

How do you write multiplication in C++?

- #include <iostream> using namespace std;
- int main()
- { int x, y, multiplication;
- cout << "Enter two integers for multiplication: ";
- cin >> x >> y;
- // stored result in third variable. multiplication = x * y;
- // Prints multiplication value.

The **getch**() **function** is used to catch a character from the keyboard. The **getch**() **function** reads a single character from the keyboard but does not show on the screen. For this functionality, you can use the **getch**() **function** to hold the output window until hitting any key from the keyboard.

- Syntax. The syntax of a while loop in C++ is − while(condition) { statement(s); }
- Flow Diagram. Here, key point of the while loop is that the loop might not ever run.
- Example. Live Demo.

- Select data for the chart.
- Select Insert > Recommended Charts.
- Select a chart on the Recommended Charts tab, to preview the chart. Note: You can select the data you want in the chart and press ALT + F1 to create a chart immediately, but it might not be the best chart for the data.
- Select a chart.
- Select OK.

So **10 factorial** (written as **10**! ) is: 1⋅2⋅3. ⋅9⋅**10**. You can work this out on your calculator.

- long factorial(int);
- int main() { int n;
- printf("Enter a number to calculate its factorial "); scanf("%d", &n);
- printf("%d! = %ld ", n, factorial(n));
- return 0; }
- long factorial(int n) { int c; long r = 1;
- for (c = 1; c <= n; c++) r = r * c;
- return r; }

By definition, a **factorial** is n! can be written as n * (n-1)! . In other words, the result of **factorial**(n) can be calculated as n multiplied by the result of **factorial**(n-1) .

To **find 5 factorial**, or **5**!, simply use the formula; that is, multiply all the integers together from **5** down to 1. When we use the formula to **find 5**!, we get 120. So, **5**! = 120.

The answer of **0 factorial** is 1. There are no calculations, nothing! All you have to do is write down 1 wherever and whenever you see **0**!

What is **Special Number**. A **number** is known as **Special number** when sum of the factorial of digits is equal to the original **number** (given **number**). Examples: Below are examples of numbers which are **Special**.

Program To **Calculate Factorial** of a Number **using For Loop**. In mathematics,the **factorial** of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n. For example, 5 ! = 5 × 4 × 3 × 2 × 1 = 120.
