# Write a program to find factorial of number using function

For factorial of any other number the process involves one comparison, one multiplication, one subtraction, and one function call. One of its advantages is that when we need to make changes to code then instead of changing the complete code, we can just modify the function concerned.

### Algorithm to find factorial of a number using recursion

Now for fact 5 num is 5 which is not equal to 0, therefore flow goes to the else statement where in return statement a recursive call is made and fact 4 is made. For single-precision inputs, the result is exact when n is less than or equal to Larger values of n produce a result that has the correct order of magnitude and is accurate for the first 8 digits. In the for loop, the value of factorial is multiplied with each integer and stored successively till the input number is reached. This is because single-precision numbers are only accurate up to 8 digits. The values in the last column indicate the saturation point; that is, the first positive integer whose actual factorial is larger than the maximum representable value in the middle column. Data type. Factorial Using Functions This approach is known as a modular approach and should be followed for programming as it is quite efficient. The for loop is executed for positive integers except for 0 for which test condition is false and thus fact remains zero. Factorial Using Recursion Recursion is the process in which a function calls itself and the corresponding function is called recursive function. This process is repeated until the required value is obtained. The process is repeated till the base condition, i. One of its advantages is that when we need to make changes to code then instead of changing the complete code, we can just modify the function concerned. If the integer entered is negative then appropriate message is displayed. The solution to the base condition is provided while the solution to the larger value can be solved by converting to smaller values till the base solution is reached and used.

Factorial Using Functions This approach is known as a modular approach and should be followed for programming as it is quite efficient. For the integer data types, the saturation value is equal to the maximum value in the middle column.

It consists of two parts- a base condition and a recursive call.

The value of factorial is displayed. For single-precision inputs, the result is exact when n is less than or equal to Factorial Using Recursion Recursion is the process in which a function calls itself and the corresponding function is called recursive function.

Saturation The table below describes the saturation behavior of each data type when used with the factorial function.

## Factorial program in c using for loop

For single and double, all values larger than the maximum value are returned as Inf. The solution to the base condition is provided while the solution to the larger value can be solved by converting to smaller values till the base solution is reached and used. For factorial of any other number the process involves one comparison, one multiplication, one subtraction, and one function call. It consists of two parts- a base condition and a recursive call. Example: 5 Example: [0 1 2 3 4] Example: int16 [10 15 20] Data Types: single double int8 int16 int32 int64 uint8 uint16 uint32 uint64 Tips Limitations For double-precision inputs, the result is exact when n is less than or equal to If the integer entered is negative then appropriate message is displayed. Larger values of n produce a result that has the correct order of magnitude and is accurate for the first 15 digits.

Larger values of n produce a result that has the correct order of magnitude and is accurate for the first 15 digits. This is because single-precision numbers are only accurate up to 8 digits.
