  	int computed_gpa(int gpa)

			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;
}

Its not an exact repost, now that I look closer, but don't think you're understanding structures and the need for separating code into functions.

Since its not an exact repost, I'll try to lead you in the right direction:

C++

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;
};

This code is clearly repeating, make a function to do so, then loop through all the course:

C++

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");

...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];
};

Solution 2

your code

MIDL

printf("Enter credit hour for course 9  :");
        scanf("%d",  &s->ch_cs9);
        printf("\n");

try this in every line:

MIDL

printf("\n Enter credit hour for course 9 :");
                  scanf("%d",&s->ch_cs9);
