Announcements - C Programming
You need to show some minimal effort first.
At least you should know enough printf/scanf to be able to input all the data and print it back out again.

You should describe your requirements in words more clearly, show us what you have tried and tell us how does it not work.

Code:

---

#include<stdio.h>
#define s scanf
#define p printf

main()
{
    char fn[25],sn[25];
    char tf[25],sf[25];
    char sec[25],sub[25];
    float gr;
    char answer;

    clrscr();



        p("Enter your Name: ");
        s("%s %s",&fn,sn);

        p("Enter your Section: ");
        s("%s",&sec);

        p("Enter your Subject: ");
        s("%s",&sub);

        p("Enter Name of your teacher: ");
        s("%s %s ",&tf,sf);

        p("Enter your Grade:");
        s("%f",&gr);

        clrscr();
    do
    {

--this is not working--

example
if grade was 95 the
grade:95
equvalent: 5
remarks: passed

if grade was 74 the
grade:74
equvalent: 5
remarks: failed

if grade was 96 the
grade:96
equvalent: nto in range
remarks: not in range

Well you might want to start fixing the following warnings and errors:

These are rather important errors that could contribute to it "not working".

getch(), clrscr(), exit() ... do you even know where these functions come from? You need to include the relevant headers.

#define s scanf
#define p printf

You do not understand how hard I want you to hit the delete key for these two statements. I want you to hit it so hard, that can't be typed ever again in that particular arrangement.

You might do better if you got rid of those stupid p/s macros for printf/scanf, and used more meaningful variable names like studentGrade instead of gr

> if (95>=gr && gr>=91)
This is unnecessarily confusing, when you then switch over to doing this
> else if (gr<=85 || gr>=81)

Ignore all the operand-swapping zealots (their advice is locked in the 1980's), and just write your expressions as you would say them in natural English.
You would normally say
if grade is less than or equal to 95

You would never tell people
if 95 is bigger than grade

Concerning the code in #6 I would like to know if you even thought about what you did, or tried it. Because it should crash.

scanf requires an address to store information from the user in, just like all versions of scanf. Now, since an array decays to a pointer to the first element, which contains said address, you do not need to use the & operator on a character array. The proper response was NOT to nerf all of your arrays, as if to get the program to work by magic.

Code:

---

#include<stdio.h>

main()
{
    char firstname,surname;
    char teachername,teachersurname;
    char section,subject;
    float grade;

    clrscr();

    do
    {
        printf("Enter your Name: ");
        scanf("%s %s ",&firstname,surname);
       
        printf("Enter your section ");
        scanf("%s",&section);

        printf("Enter your subject: ");
        scanf("%s",&subject);

        printf("Enter Name of your teacher: ");
        scanf("%s %s ",&teachername,ts);

        printf("Enter your grade:");
        scanf("%f",&grade);

        clrscr();

        If (95>=grade || grade>=91)
        {
            printf("Student Name: %s %s\n",firstname,surname);
            printf("section %s\n",section);
            printf("subject: %s\n",subject);
            printf("Teacher Name: %s %s\n",teachername,ts);
            printf("grade : %0.f\n",grade)
            printf("Equivalent Remarks: 1\n");
            printf("REMARKS: PASSED \n");
        }

        else if (grade=<90 || grade>=86)
        {

no display output!!!

Fix some variable names.
Change some of your chars into char arrays (all those with warning: format ‘%s’ expects argument of type ‘char *’, )

Given your other posts, it looks like you can't be bothered and are looking for an easy ride by trying to get someone else to do the work.

Getting better (slowly) - KEEP AT IT!

Instead of continuing posting code which is full of errors I suggest to either ask specific questions or dump your garbage somewhere else.
