Can someone correct this🤔

Question

Instead of the result:

Enter the first number: 1.6
Enter the second number: -2
Enter the third number: -1
Product = 3.2

#include <stdio.h>

int main()
{
int a, b, c;
int product;
printf("Input the first integer: ");
scanf("%lf", &a);
printf("Input the second integer: ");
scanf("%lf", &b);
printf("Input the third integer: ");
scanf("%lf", &c);
product = a*b*c;
printf("Product = %.2lf\n", product);
}

The result of my code is:
Input the first integer: 1.6
Input the second integer: -2
Input the third integer: -1
Product = 0.00

Why is 0.00 in the product instead of 3.2?

Your entered input is a type of double or float because it contains decimal so you can't take float or double input as a int

So you can use float or double like this:

float a, b, c, product;

scanf("%f", &a);
scanf("%f", &b);
scanf("%f", &c);
product = a * b * c;
printf("Product = %.2f\n", product);

Answer 2

Use `double` as data type for <a>, <b>, <c> and <product> variable rather than `int`

double a, b, c, product;
