Question

can anyone tell me the problem of this programme?
#include int main () { double a,b,bmi; printf("enter your weight(kg) and height(m)\n" ,a ,b); scanf("%d%d" , &a ,&b); bmi = a/(b*b); printf("your BMI :\n" ,bmi); if (bmi<18.5) printf("you are under weight\n"); if (bmi>=18.5 && bmi<=24.9) printf("you are normal\n"); if (bmi<=29.9 && bmi>=24.9); printf("you are overweight\n"); if (bmi>=29.9) printf("you are obese\n"); return 0; }

Answer 1

printf("enter your weight(kg) and height(m)\n" ,a ,b);

I see no reason for a and b in this statement.


scanf("%d%d" , &a ,&b);

%d is for integers, %f is for float. "%d%d" doesn't have any separation between the two numbers. "%d %d" separates the integers with a space.


if (bmi<=29.9 && bmi>=24.9);

if statements don't have a semi-colon.
