C Program to Calculate BMI Using 2D Array Formula and Mathematical Explanation
The mathematical foundation of the c program to calculate bmi using 2d array relies on the standard BMI formula: BMI = Weight(kg) / Height(m)². When implementing this in a 2D array structure, the formula is applied to each row representing an individual’s data.
In the c program to calculate bmi using 2d array, the calculation process involves iterating through each row of the array, extracting weight and height values, applying the BMI formula, and storing the result back in the appropriate location within the 2D array structure. This systematic approach ensures accurate and efficient processing of multiple BMI calculations.
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| weight | Patient weight in 2D array | kilograms (kg) | 30-200 kg |
| height | Patient height in 2D array | meters (m) | 1.0-2.5 m |
| bmi_array[i][j] | 2D array storing patient data | N/A | Array structure |
| calculated_bmi | Result of BMI calculation | BMI unit | 10-50 BMI |
| row_index | Index for patient number | integer | 0 to n-1 |
Mathematical Derivation
The c program to calculate bmi using 2d array follows these steps for each patient record in the array:
- Extract weight from bmi_array[i][WEIGHT_INDEX]
- Extract height from bmi_array[i][HEIGHT_INDEX]
- Apply formula: bmi_result = weight / (height * height)
- Store result in bmi_array[i][BMI_INDEX]
- Determine category based on BMI value
Practical Examples of C Program to Calculate BMI Using 2D Array
Example 1: Healthcare Clinic Implementation
A local clinic needs to process BMI calculations for 50 patients during their annual health screening. Using the c program to calculate bmi using 2d array approach, they can efficiently process all patient data in a single operation.
Input: 2D array with 50 rows and 3 columns [weight, height, bmi]. Patient data includes weights ranging from 50-100 kg and heights from 1.5-2.0 meters. The c program to calculate bmi using 2d array processes each row, calculates BMI using the formula weight/(height*height), and categorizes each patient according to BMI standards.
Output: The program returns a complete dataset with BMI values and categories for all 50 patients, allowing healthcare professionals to quickly identify patients requiring follow-up care. The c program to calculate bmi using 2d array approach reduces processing time significantly compared to individual calculations.
