    Question 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.

    You assigned 0 to your variable i multiple times, use the same logic (and the same operator) to assign 'A' to your variable.

    On a sidenote: why are people from the indian subcontinent so obsessed with using software that is way older than they are? Turbo C is software stoneage, I've been using more recent compilers 15 years ago in school. There are many good and free compilers out there, if Turbo C is not an external requirement by your teacher, go grab a great free compiler from this millenium.

    It's your logic. Assume per is 80.

    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.
