Thread: Who can check my code?

//My program working but i don't know, i did it in correct way or not.?

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>


struct triagle
{
    float point1;
    float point2;
    float point3;
};


float tr_perimetr(float x,float y,float z)
{   
    float perimetr;
    perimetr = x+y+z;
    
    return perimetr;
}




int main()
{   
    srand(time(NULL));
    struct triagle perimetr;
    int num;
    perimetr.point1 = (rand()/(float)RAND_MAX)*(10.0+10.0)-10.0;
    perimetr.point2 = (rand()/(float)RAND_MAX)*(10.0+10.0)-10.0;
    perimetr.point3 = (rand()/(float)RAND_MAX)*(10.0+10.0)-10.0;
    printf("Perimetr of triangle with edges of %.1f\t%.1f and %.1f = %.1f",perimetr.point1,perimetr.point2,perimetr.point3,tr_perimetr(perimetr.point1,perimetr.point2,perimetr.point3));
    
    
    return 0;
}
