hello all, I am taking an intro to programming course and am finding an issue with one of my labs. it is a BMI calculator program. Below is what I have so far but when i build it to test it out i get "return value ignored scanf for line 16 and 18. for line 17 and 19 i get "scanf this function may be unsafe consider using scanf_s instead. to disable deprecation use CRT SCURE NOT WARNINGS.

I have that included as you can see but still get the same answer. i dont know what i am missing, or even if the title of my post is correct. I am only 7 weeks in to my course and have been struggling a bit anyways.

I also tried plugging the code into chatgpt but it did not help.

​

#define _CRT_SCURE_NO_WARNINGS

​

#include <stdio.h>

​

​

int main()

{

float weight, height, bmi;

​

printf("\\n\\t Enter Weight in lbs\\t");

scanf("%f", &weight);

printf("\\n\\t Enter height in inches\\t");

scanf("%f", &height);

​

bmi = weight / (height \* height);

​

if (bmi <= 18.5)

{

    printf("BMI is : %.22f -> Underweight", bmi);

}

else if (bmi <= 24.9)

{

    printf("BMI is : %.2f -> Normal", bmi);

}

else if (bmi >= 25 && bmi <= 29.9)

{

    printf("BMI is : %.2f -> Overweight", bmi);

}

else

    printf("BMI is : %.2f -> Obese", bmi);

​

return 0;

}
