Thread: Help Please!

Please tell me if I am on the right track. This program takes 20 student # with grades and print them on the screen.
Here is what I have until now. I am stuck at the display now. How do I get the user entered information and display it?.

Code:

#include <stdio.h>

#define MAX_NUM_STUDENTS 20
#define TRAILER -9999

input (float* , int* );
display (float* , int* );

int main()
{
  int student_num;
  float grade;

	input (float* grade, int* student_num);
	display (float* grade, int* student_num);

}

void input(float* grade, int* student_num)
{

	for (student_num < MAX_NUM_STUDENTS; student_num != TRAILER; student_num++)
		{
		printf ("Please enter up to %d students number.", MAX_NUM_STUDENTS);
		scanf ("%d", &student_num);
		}
	for (grade < MAX_NUM_STUDENTS; grade != TRAILER; grade++)
		{
		printf ("Please enter up to %f grades.", MAX_NUM_STUDENTS);
		printf ("Enter %d to signal end of data.", TRAILER);
		scanf ("%f", &grades);
		}
}

void display()

	{
		printf (" Student # with Grades:");
		printf ("\t Student # \t Grades \n");
		printf ("\t_________\t_______\n");
}

Thanks

You are on the right track you just need an array to store what the user enters. You could pass the array as the argument on your display function to get it done.

i dont know how you could display 20 values at the same time on the screen
do look at the output generated by my program
it's done using TurboC

Code:

#include <stdio.h>
#include<conio.h>
#define MAX_NUM_STUDENTS 20
#define TRAILER -9999

void input (float* , int* );
void display (float* , int* );

int main()
{
  int student_num[20];
  float grade[20];

	clrscr();
	input (&grade,&student_num);

	display (&grade,&student_num);
	getch();

	return 0;
}

void input(float *grade, int *student_num)
{
	int i;
	for (i = 1;i != 20; i++)
		{
		printf ("Please enter up to %d students number.", MAX_NUM_STUDENTS);
		scanf ("%d", &student_num[i-1]);
		}
	for (i = 1; i != 20; i++)
		{
		printf ("Please enter up to %d grades.", MAX_NUM_STUDENTS);
		scanf ("%f", &grade[i-1]);
		}
}

void display(float *grade,int *student_num)
{
	int i;
	for(i = 1; i != 20; i++)
	{
		printf ("\n Student #%d with Grades:%d",&student_num[i-1],&grade[i-1]);
		printf ("\t Student #%d \t Grades%d \n",&student_num[i-1],&grade[i-1]);
		printf ("\t_________\t_______\n");
	}
}

Quit posting non-portable turbo-c code.
