#include<stdio.h>
struct stu
{
    int num;
    char name[20];
    char sex;
    float score;
}boy[5]=
{
    {101,"zhou ping",'M',45},
    {102,"zhang ping",'M',62.5},
    {103,"cheng ling",'F',92.5},
    {104,"wang ming",'M',62.2},    /*出现警告处*/                                 
    {105,"liu fang",'F',62.5}
};
int main()
{
    struct stu *p;
    printf("no\tname\t\t\tsex\tscore\t\n");
    for(p=boy;p<boy+5;p++)
        printf("%d\t%s\t\t%c\t%f\t\n",p->num,p->name,p->sex,p->score);
    return 0;
}
编译时有一个警告，   'initializing' : truncation from 'const double ' to 'float '  把62.2改成其他的数有的可以有的还是不行，各位大神求指教啊！！！
