int computed_gpa(int gpa)
{
char grade;
if(gpa >=90)
grade = ''4'';
else if(gpa >=80)

else if(gpa >=70)
grade = ''2'';
else if(gpa >=60)
grade = ''1'';
else
grade = ''0'';
return grade;
}
我可以知道为什么只显示最后一个输入吗? 1-9的输入未显示
may i know why it just show the last input only? 1-9 input did not show out
推荐答案
由于它不是确切的重新发布，因此我将尝试引导您朝着正确的方向前进:
Since its not an exact repost, I''ll try to lead you in the right direction:
struct STUDENT_REC{
char name[100];
int gpa;
int total_hours;
struct ch_cs1; //<-- What kind of structure is this? You're declaring that its a struct but not what type.
struct ch_cs2;
struct ch_cs3;
struct ch_cs4;
struct ch_cs5;
struct ch_cs6;
struct ch_cs7;
struct ch_cs8;
struct ch_cs9;
struct ch_cs10;
};
这段代码显然是重复的，创建一个函数，然后遍历所有过程:
This code is clearly repeating, make a function to do so, then loop through all the course:
printf("Enter Subject Code :");
gets(s->subject_code);
printf("Enter Subject Name :");
gets(s->subject_name);
printf("Enter Lecturer Name :");
gets(s->lecturer_name);
printf("Enter credit hour for course 1 :");
scanf("%d", &s->ch_cs1);
printf("\n");
...而且，结构数组也是合法的，因此实现了更简洁的实现(稍后将允许循环):
...And, arrays of structures are also legal, so a cleaner implementation (that''ll allow the looping later):
struct STUDENT_REC{
char name[100];
int gpa;
int total_hours;
struct COURSE courses[10];
};
您的代码
printf("Enter credit hour for course 9 :");
scanf("%d", &s->ch_cs9);
printf("\n");
在每一行中尝试一下:
try this in every line:
printf("\n Enter credit hour for course 9 :");
scanf("%d",&s->ch_cs9);
