Flowgorithm Built-in Functions
Flowgorithm Built-in Functions
In this tutorial, we will learn Flowgorithm Built-in Functions. Built-in functions are predefined and ready to use, also known as Intrinsic Functions. We don’t need to write code for these functions; they are invoked directly in the flowcharts.
Built-in Functions
Some examples of the intrinsic functions are:
Mathematical Functions
Flowgorithm mathematical functions are as follows:
| Flowgorithm Intrinsic Function | Description |
| Log(x) | The log(x) function computes the natural logarithmic of the input parameter x. |
| Log10(x) | The log10(x) function computes the logarithmic of the base 10. |
| Sqrt(x) | Sqrt(x) function computes the square root of the input parameter x. |
| Abs(x) | The abs(x) function returns the absolute value of the input parameter x. |
| Random(n) | The Random(n) function returns a random number between o and n-1. |
Trigonometric Functions
Flowgorithm intrinsic functions are as follows:
| Flowgorithm Intrinsic Function | Description |
| Cos(x) | The cos(x) function computes the cosine of the angle x. (x should be in radians.) |
| Sin(x) | The sin(x) function computes the sine of angle x. (x should be in radians.) |
| Tan(x) | The tan(x) function computes the tangent of angle x. x should be in radians. |
String Functions
Flowgorithm string functions are as follows:
| Flowgorithm Intrinsic Function | Description |
| Len(str) | The Len(str) function returns the length of the string |
| Char(str, index) | The Char(str, index) function returns the character of the string at the index. Characters in the string are indexed starting from 0. |
Other Functions
Some other functions are as follows:
| Flowgorithm Function | Description |
| Size(arr) | The Size(arr) function returns the number of elements in the array arr. |
| EOF() | The EOF() function is the end-of-file function. This returns True if the end of the input file was reached. Flowgorithm supports two modes to open a file: Read and Write. We can use this function while reading the file in the Read mode. |
Data Type Conversion
Data type conversion functions like:
These functions convert the input parameters from one data type to another:
Example
Let’s use an intrinsic function sin(x) in the flowchart to understand better. Sin(x) computes the trigonometric sine of the input argument x. The input parameter x for the function should be in radians. sin(x) is a built-in function. We don’t need to define the function in the flowchart.
User-defined Functions
Unlike built-in functions, we need to provide define and provide an implementation for the user-defined functions. We can create a user-defined function in Flowgorithm flowcharts. To know more
