return 0；
}

主要是结构体不太懂···请各位大虾帮帮忙····

1、if(i=0)应该是if(i==0)，否则死循环
2、return 0；分号有问题，改为"return 0;",否则无法编译。

修改过后还是有问题····
：#include <stdio.h>
struct SCORE
{
    char math;
    int  gpa1;
    char chinese;
    int  gpa2;
    char english;
    int  gpa3;
    char c;
    int  gpa4;
    char s;
    int  gpa5;
    char jd;
    int  gpa6;
    char physical;
    int  gpa7;
    int  score;
}first;
main(){
  int i;
  float e;
  printf("This is the first score in your college\n ");
  printf("please fill in carefully!\n");
  for(i=0;i<7;i++){
      if(i==0){
         printf("first.math");
         scanf("%.1f",&first.gpa1);}
      else if(i==1){
          printf("first.chinese");
          scanf("%.1f",&first.gpa2);}
      else if(i==2){
          printf("first.english");
          scanf("%.1f",&first.gpa3);}
      else if(i==3){
          printf("first.c");
          scanf("%.1f",&first.gpa4);}
      else if(i==4){
          printf("first.s");
          scanf("%.1f",&first.gpa5);}
      else if(i==5){
          printf("first.jd");
          scanf("%.1f",&first.gpa6);}
      else if(i==6){
          printf("first.physical");
          scanf("%.1f",&first.gpa7);}
      else if(i==7){
          e=0;
          e=(first.gpa1+first.gpa2+first.gpa3+first.gpa4+first.gpa5+first.gpa6)/6.0;
          printf("&.1f",e);}
  }

return 0;
}

报的什么错？？

把scanf("%.1f",&first.gpa1);
换成scanf("%d",&first.gpa1);
你最开始声明的是int型变量，你试试

#include <stdio.h>
struct SCORE
{
    char *s1;
    int  gpa1;
    char *s2;
    int  gpa2;
    char *s3;
    int  gpa3;
    char *s4;
    int  gpa4;
    char *s5;
    int  gpa5;
    char *s6;
    int  gpa6;
    char *s7;
    int  gpa7;
}first;
int main()
{
  int i;
  float e;
  printf("This is the first score in your college\n ");
  printf("please fill in carefully!\n");
  for(i=0;i<7;i++)
    {
      if(i==0){first.s1="math";
         printf("%s:",first.s1);
         scanf("%d",&first.gpa1);}
      else if(i==1){first.s2="chinese";
          printf("%s:",first.s2);
          scanf("%d",&first.gpa2);}
      else if(i==2){first.s3="english";
          printf("%s:",first.s3);
          scanf("%d",&first.gpa3);}
      else if(i==3){first.s4="c";
          printf("%s:",first.s4);
          scanf("%d",&first.gpa4);}
      else if(i==4){first.s5="s";
          printf("%s:",first.s5);
          scanf("%d",&first.gpa5);}
      else if(i==5){first.s6="jd";
          printf("%s:",first.s6);
          scanf("%d",&first.gpa6);}
      else if(i==6){first.s7="phasical";
          printf("%s:",first.s7);
          scanf("%d",&first.gpa7);}
      
    }
          e=(first.gpa1+first.gpa2+first.gpa3+first.gpa4+first.gpa5+first.gpa6+first.gpa7)/7.0;
          printf("%.1f\n",e);

return 0;
}
是这个意思吗？

额、基础不行啊。先把基本数据了类型和构造数据类型练练在来看结构体这种特殊的构造数据类型吧

没有错误 但运行不下去···

恩  谢谢了！
