[C language] (array mode) outputs a set of results in the highest score and the lowest score

Two different way to obtain the maximum and minimum

Code 1:

#include <stdio.h>
int main()
{
    float score[5], sum = 0, max, min;
    int i;
    printf("请输入5名童鞋的成绩：\n");
    for (i = 0; i < 5; i = i + 1)
        scanf_s("%f", &score[i]);
    max = min = score[0];
    for (i = 0; i < 5; i = i + 1)
    {    
        if (max <=Score [I]) 
            max = Score [I];
     IF (min> = Score [I]) 
        min = Score [I]; 
} 
the printf ( " maximum score:. 1F% \ n- " , max); 
the printf ( " lowest score:% 1F \ n-. " , min); 
}

Code 2:

#include <stdio.h>
int main()
{
    float score[5], sum = 0 ;
    int i,max, min;
    printf("请输入5名童鞋的成绩：\n");
    for (i = 0; i < 5; i = i + 1)
        scanf_s("%f", &score[i]);
    max = min = 0;
    for (i = 0; i < 5; i = i + 1)
    {    
        if (max <=Score [I]) 
            max = I;
     IF (min> = Score [I]) 
        min = I; 
} 
the printf ( " subscripts:.% d score is the highest score:% 1F \ n- " , max, Score [ max]); 
the printf ( " subscripts: results of% d lowest score:% 1F \ n-. " , min, score [min]); 
}
