C if else loops don't work

Question

I don't understand why the if and if else loops don't work. I also don't understand why I can't get value grade form the program (not IRL grade) past B. The logic just does not flow down. All this program is meant to do is take three input grades int (0 -100) and give a grade based on the "> or <" that are set. Yet they don't work for me. What can I do to get the if else to work? Thanks.

Answer 1

Your program doesn't compile because your else statement is wrong:

 if (test3 >= 90)
 {
   printf("Good job you got a A %d\n", average);
 }
 else if // << here is the problem
 {
   printf("Easy Beezy you got a B %d for the class\n", average);
 }

Just drop the if after else:

 if (test3 >= 90)
 {
   printf("Good job you got a A %d\n", average);
 }
 else
 {
   printf("Easy Beezy you got a B %d for the class\n", average);
 }

make your problem statement clear. your program is not running cause you dint use if-else-if properly. if you use else-if then there should be a condition to check. if there is no condition then you can use if-else. i.e. your program will run if you change

if (test3 >= 90)
        {
            printf("Good job you got a A %d\n", average);
        }
        else if
        {
            printf("Easy Beezy you got a B %d for the class\n", average);
        }
    }
    else if (average >= 50 && average <= 70)
    {

        if (test2_test3Av >= 70)
        {
            printf("You passed congrats you have a C %d for the class\n", average);
        }
        else if
        {
            printf("You have a D for the class %d\n", average);
        }

this code part to

if (test3 >= 90)
        {
            printf("Good job you got a A %d\n", average);
        }
        else
        {
            printf("Easy Beezy you got a B %d for the class\n", average);
        }
    }
    else if (average >= 50 && average <= 70)
    {

        if (test2_test3Av >= 70)
        {
            printf("You passed congrats you have a C %d for the class\n", average);
        }
        else
        {
            printf("You have a D for the class %d\n", average);
        }
}

but logic you need to check. error in coding is this

Answer 3

else if (average >= 50 && average <= 70)
{

}

if (test3 >= 90)
 {
   printf("Good job you got a A %d\n", average);
 }
 else
 {
   printf("Easy Beezy you got a B %d for the class\n", average);
 }
