Explanation
- Function
qualityControlCheck(int batchSize, double defectRate):- Purpose: Simulates the quality control check for a batch of items.
- Parameters:
batchSize: The number of items in the batch.defectRate: The probability of an item being defective.
- Implementation:
- Iterates through each item in the batch.
- Uses a random number to determine if an item is defective based on the
defectRate. - Counts and returns the number of defective items.
- Main Function:
- Setup:
- Seeds the random number generator for simulating the defect checks.
- Prompts the user for the batch size and defect rate.
- Validates that the defect rate is within the range [0, 1].
- Simulation:
- Calls
qualityControlCheckto determine the number of defective items. - Outputs batch size, defect rate, number of defective items, and percentage of defective items.
- Calls
- Setup:
Usage
- Quality Control Simulation: Demonstrates how to simulate the detection of defective items in a manufacturing batch.
- Statistical Reporting: Provides insights into the quality of the batch based on the defect rate.
