delphi basics generating random number
To generate a random number in Delphi, you can use the
Random function from the
System unit. The
Random function returns a random number between 0 and a specified value.
Here's an example of how to generate a random number between 1 and 100:
Randomize; // Initialize the random number generator
randomNumber := Random(100) + 1; // Generate a random number between 1 and 100
// Use the random number as needed
In the above example,
Randomize is called to initialize the random number generator with a seed value based on the current time. This ensures that each run of the program produces a different sequence of random numbers.
Random function is then used to generate a random number between 1 and 100. The
Random function takes an integer parameter that specifies the upper bound of the range (exclusive). By adding 1 to the result, we ensure that the random number is inclusive of the upper bound.
You can modify the code to suit your specific needs, such as changing the range of the random number or using the generated random number in your program logic.
