This program is to calculate BMI values. But its only getting inputs then not showing any outputs. can anyone help me with this

Question

void CalcBMI(float weight[],float height[],float BMI[],int size)
{
float bmi=0;
for(int i=0; i<size; i++)
{
bmi=weight[i]/((height[i]*0.01)*(height[i]*0.01));
cin>>BMI[i];
}
}

is there any wrong in this function?

Answer 1

to print anything use std::cout function of c++

Answer 2

Hi! You trye to solve BMI project? Or something else?

Answer 3

there's many mistakes in few lines of code :D

assuming the function is designed to handle arrays of height and weight values and print each pair bmi:

1) you doesn't need to have a BMI array argument, as you doesnt return values (and if you expect to read the modified array outside of the function, you must pass it by reference rather than by value)

2) you use 'bmi' local variable to store each bmi's values

3) you use height values divided by 100 (multiplied by 0.01) then squared: which unit is supposed to be populated your height array?
... as bmi formula is weight (kg) / height (meter) ^ 2

4) instead of printing the computed 'bmi', you ask user for input a value stored at BMI array current index...
