#include <stdio.h>

int main()
{
    float a, b, c, d, sum = 0;
    printf("Enter the first number: ");
    scanf("%f", &a);
    if(a < 0)
    {
        sum += a;
    }
    printf("Enter the second number: ");
    scanf("%f", &b);
    if(b < 0)
    {
        sum += b;
    }
    printf("Enter the third number: ");
    scanf("%f", &c);
    if(c < 0)
    {
        sum += c;
    }
    printf("Enter the fourth number: ");
    scanf("%f", &d);
    if(d < 0)
    {
        sum += d;
    }
    printf("Sum of all negatives = %.2f \n", sum);
    
    return 0;
