Question

Write a C program that reads the height and weight of a person and calculates the body mass index (bmi) according to formula bmi = weight/(height)2. Your program should display a qualitative assessment of the weight according to the following table:

BMI value
Letter Grade
[0-20)
Below normal weight
[20-25)
Normal weight
[25-30)
Overweight
>=30
Obese

Sample Output:
Enter your weight in kilos: 70
Enter your height in meters: 1.80
Result: Normal weight
Test values: (70 1.8) (50, 1.9) (90, 1.6), (140, 1.7) 

in c code

**********************************************************************************************

Please find the below program

**************************************************************************************************

#include <stdio.h>
int main()
{
float weight, height; //declare the variables to store weight and height
int bmi; //declare the variable to store the body mass value
printf("Enter the weight in kgs:");
scanf("%f", &weight); //read the value for weight
printf("Enter the height in meters:");
scanf("%f", &height); //read the value for height
bmi = weight / (height * height); //calculating the body mass value
if(bmi > 0 && bmi < 20) //checking the bmi value less than 20
{
printf("Result:Below Normal Weight");
}
else if(bmi >20 && bmi < 25)//checking the bmi value is between 20 and 25
{
printf("Result: Normal Weight");
}
else if(bmi>25 && bmi<30)//checking the bmi value is between 25 and 30
{
printf("Result: Overweight");
}
else //the value is greater than or equal to 30
{
printf("Result: Obese");
}
return 0;
}
