sorry, i may have made a cross-post:
but i finally got the program work with this code:
#define BUFFERMAXSIZE 80
struct record{
char name[20];
char student_id[7];
char class_id[4];
char position[25];
};
int input_data()
{
FILE *output_file;
output_file = fopen("results.txt", "a+");
struct record student;
char ch;
char buffer[BUFFERMAXSIZE];
fflush (stdin);
//data ==> output_file
printf("Name: ");
gets(student.name);
strcat(student.name, "\n");
printf("Class: ");
gets(student.class_id);
strcat(student.class_id, "\n");
printf("Student ID: ");
gets(student.student_id);
strcat(student.student_id, "\n");
printf("Position: ");
gets(student.position);
strcat(student.position, "\n");
printf("Are you sure to add new member/change member information(Y/N)? ");
ch = getchar();
ch = toupper(ch);
if( ch == 'Y' )
{
fputs(student.name,output_file);
fputs(student.class_id, output_file);
fputs(student.student_id, output_file);
fputs(student.position, output_file);
fclose(output_file);
input_screen();
}
else if( ch == 'N'){
return 0;
fclose(output_file);
}
else{
printf("\nInvalid Choice, Please try again");
fclose(output_file);
}
printf("\n");
}
but why it doesn't work with this thingy::::::
int input_data()
{
FILE *output_file;
output_file = fopen("results.txt", "a+");
struct record student;
char ch;
char buffer[BUFFERMAXSIZE];
fflush (stdin);
//data ==> output_file
printf("Name: ");
gets(buffer);
strcpy(student.name, buffer);
strcat(student.name, "\n");
fflush (stdin);
printf("Class: ");
gets(buffer);
strcpy(student.class_id, buffer);
strcat(student.class_id, "\n");
printf("Student ID: ");
gets(buffer);
strcpy(student.student_id, buffer);
strcat(student.student_id, "\n");
printf("Position: ");
gets(buffer);
strcpy(student.position, buffer);
strcat(student.position, "\n");
printf("Are you sure to add new member/change member information(Y/N)? ");
ch = getchar();
ch = toupper(ch);
if( ch == 'Y' )
{
fputs(student.name,output_file);
fputs(student.class_id, output_file);
fputs(student.student_id, output_file);
fputs(student.position, output_file);
fclose(output_file);
input_screen();
}
else if( ch == 'N'){
return 0;
fclose(output_file);
}
else{
printf("\nInvalid Choice, Please try again");
fclose(output_file);
}
printf("\n");
}
is that one more null character exist inside the buffer????pls reply my question
