    c program

    I have this program that I wrote a few weeks ago:
    Code:
    #include<stdio.h>
    #include<conio.h>
    int main()
    {
      float grade;
      printf("\nEnter Grade:\n");
      scanf("%f", &grade);
      if( grade >= 90)
      printf("Your grade is:A");
      else if ( grade >= 80)
      printf("Your grade: B");
      else if ( grade >= 70)
      printf("Your grade: C");
      else if ( grade >= 60)
      printf("Your grade: D");
      else if ( grade <= 59)
      printf("Your grade: F");
    return 0;
    _getch();
    }
    Now i have to repeat this for 6 students. How do I know which loop to use?

    Are you sitting in class during a test asking us these questions?

    Unless the grade variable can be a floating point number, always use an integer for number variable data types.

    You can use a while loop, but if you know the number of times you need to loop (6 in this case), then a for loop is easiest and clearest.

    A development process
    Study carefully what happens at step 5.

    When you have a function to process one student, write a loop to call it 6 times.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
