look at the structure -- credit is an array of floats and you are attempting to use it as if it were a single float object. Change the structure to remove the arrays

 struct cgrade
 {
    char course[50]; // room for 50 character course name
    float credit;
    float grade;
 };
 struct cgrade
 {
    char course[50]; // room for 50 character course name
    float credit;
    float grade;
 };

>>gets(GPA[i].course);
never, ever use gets() function because it can cause your program to crash if you enter more characters than the input buffer can hold. Use fgets() instead

fgets(GPA[i].course, sizeof(GPA[i].course), stdin);
