Write a C program that reads three floating values and check if it is possible to make a triangle with them. Also calculate the perimeter of the triangle if the said values are valid

#include <stdio.h>
int main() {
	float  x, y, z, P, A;
    printf("\nInput the first number: "); 
    scanf("%f", &x);
    printf("\nInput the second number: ");
    scanf("%f", &y);
    printf("\nInput the third number: ");
    scanf("%f", &z);
    if(x < (y+z) && y < (x+z) && z < (y+x)) 
     {  
	 P = x+y+z;
	 printf("\nPerimeter  = %.1f\n", P);	 	 
    }
    else
    {
    	printf("Not possible to create a triangle..!");
	}
}
