Thread: Highest and lowest value

Hi. I have an applikation with 7 point variables, i write values to the variables and i whant the applikation to decide wich variable has the highest and lowest variables.

I write values to the variables like this:

PHP Code:

    float point1, point2,point3,point4,point5,point6,point7;

    printf("point 1: ");
    scanf("%f", &point1);

    printf("point 2: ");
    scanf("%f", &point2);

    printf("point 3: ");
    scanf("%f", &point3);

    printf("point 4: ");
    scanf("%f", &point4);

    printf("point 5: ");
    scanf("%f", &point5);

    printf("point 6: ");
    scanf("%f", &point6);

    printf("point 7: ");
    scanf("%f", &point7); 


Code:

float *max = &point1;
float *min = &point1;

if (point2 > *max)
{
	max = &point2;
}

if (point2 < *min)
{
	min = &point2;
}
