**Q1)** Write a program in C to input two negative integer numbers and print the product of the numbers after removing their negative sign using the abs() function.

#### Program

```
#include <stdio.h>
#include <conio.h>
#include <math.h>
int main()
{
int a,b,p;
printf("Enter 2 negative integer numbers\n");
scanf("%d%d",&a,&b);
p=abs(a) * abs(b);
printf("Product = %d",p);
return 0;
}
```

#### Output

Enter 2 negative integer numbers -5 -8 Product = 40
