Thread: Question About Grades??? (profoundly non-urgent)

Hello, I m New In C Programing And I m Using "Turbo C 3.0" For Writing Programs. I Have Written A Program Which Source Code Is Below. The Program's Logic Is That, That It Takes Information Of 3 Students And I Had Used "Structure Array" In It. And I want that After Taking Marks Of Students It Will Print Percentage Which I Had Done But i Want "Grades" As Well To Be Print. My Source Is Below I Had Tried But On "grade=='A'","grade=='B'","grade=='C'", It Accours An error "Code Has No effect". Please Help Me Out And Paste Correct Source Code In answer Thanks!

Code:

#include<stdio.h>
#include<string.h>

struct students
{
  char n[30];
  int m;
  int p;
  int u;
  int e;
}std[3];

void main()
{
  int i=0;
  float per;
  char grade;

  clrscr();
  for(i=0;i<3;i++)
  {
    printf("\t\t:: Enter Information Of Student %d ::", i+1);

    printf("\nName: ");
    scanf("%s", std[i].n);

    printf("\nMaths: ");
    scanf("%d", &std[i].m);

    printf("\nPhysics: ");
    scanf("%d", &std[i].p);

    printf("\nUrdu: ");
    scanf("%d", &std[i].u);

    printf("\nEnglish: ");
    scanf("%d", &std[i].e);
  }
  printf("\n\t\t::.Percentage Of Students.::");
  for(i=0;i<3;i++)
  {
    per=(std[i].m+std[i].p+std[i].u+std[i].e)*100/400;
    printf("\nPercentage Of %s Is %.2f%", std[i].n, per);
  }

  printf("\n\n::.Grades Of Students.::");
  if(per>=70.00)
  {
    grade=='A';
  }
  if(per>=60.00)
  {
    grade=='B';
  }
    if(per>=50.00)
  {
    grade=='C';
  }
  for(i=0;i<3;i++)
  {
    printf("\nGrade Of %s Is %c",std[i].n, grade);
  }
  getch();
}

1) == does not mean "assign to".

2) "A" is not a char. 'A' is a char.

Thanks! But can You Give Me Correct Code ????

Code:

if(per>=70.00) // yes, 80 > 70
  {
    grade=='A'; // grade is set to A
  }
  if(per>=60.00) // yes, 80 > 60
  {
    grade=='B'; // grade is set to 'B'
  }
    if(per>=50.00) // yes, 80 > 50
  {
    grade=='C'; // grade is set to 'C'
  }

You need to make sure you check for grades B downward only if it's not already determined to be an 'A'. Hint: use the "else" keyword.

Well, except for that Flintstones compiler you're using....
