C program to Calculate Body Mass Index (BMI)
Given with the weight and height of a person and the task is to find the BMI i.e. body mass index of his body and display it.
For calculating the body mass index we require two things −
- Weight
- Height
BMI can be calculated using the formula given below −
BMI = (mass or weight) / (height*height)
Where weight is in kg and height is in meters
Example
Input 1-: weight = 60.00 Height = 5.1 Output -: BMI index is : 23.53 Input 2-: weight = 54.00 Height = 5.4 Output -: BMI index is : 9.3
Approach used below is as follows −
- Input weight(kg) and height(meter) in float variables
- Apply the formula to compute the body mass index
- Print the BMI
Algorithm
Start Step 1-> Declare function to calculate BMI float BMI(float weight, float height) return weight/height*2 step 2-> In main() Set float weight=60.00 Set float height=5.1 Set float bmi = BMI(weight,height) Print BMI Stop
Example
#include<stdio.h>
//function to calculate BMI index
float BMI(float weight, float height) {
return weight/height*2;
}
int main() {
float weight=60.00;
float height=5.1;
float bmi = BMI(weight,height);
printf("BMI index is : %.2f ",bmi);
return 0;
}Output
IF WE RUN THE ABOVE CODE IT WILL GENERATE FOLLOWING OUTPUT
BMI index is : 23.53
