Hi, I cannot fix the 5 errors after trying to fix the code. Even after fixing the code it is giving me more errors which I don't understand how to fix. I tried reordering #include "student.h" and #include "bubble.h" in studentMain.cpp but it gave me more errors. Is this happening because I am compiling with the wrong command, I am compiling it all together like this: g++ studentMain.cpp bubble.cpp bubble.h student.h grades.txt. I have the modified code below and I can only edit the code in the studentMain.cpp file I cannot edit the code in the files bubble.cpp, bubble.h, and student.h: //studentMain.cpp #include #include #include "student.h" #include "bubble.h" int main() { // Create an array of 19 student pointers student *students[19]; // Allocate space for each student in the array for (int i = 0; i < 19; i++) { students[i] = (student *)malloc(sizeof(student)); } // Read in the data from the file FILE *fp = fopen("students.txt", "r"); if (fp == NULL) { printf("Error opening file\n"); return 1; } for (int i = 0; i < 19; i++) { fscanf(fp, "%s %s %d %d %d", students[i]->first, students[i]->last, &students[i]->exam1, &students[i]->exam2, &students[i]->exam3); // Calculate the student's mean students[i]->mean = (students[i]->exam1 + students[i]->exam2 + students[i]->exam3) / 3.0; } fclose(fp); // Sort the students using the bubble sort algorithm bubble(students, 19); // Find the mean, minimum, maximum, and median of the grades float mean = 0.0; float min = students[0]->mean; float max = students[18]->mean; float median = students[9]->mean; for (int i = 0; i < 19; i++) { mean += students[i]->mean; } mean /= 19.0; // Print the class statistics printf("CSCE 1040 MEAN %.2f MIN: %.2f MAX: %.2f MEDIAN: %.2f\n", mean, min, max, median); // Print the student averages for (int i = 0; i < 19; i++) { printf("%s %s %f\n", students[i]->first, students[i]->last, students[i]->mean); } // Free the allocated memory for each student for (int i = 0; i < 19; i++) { free(students[i]); } return 0; } //bubble.cpp #include #include "student.h" void bubble(student *array[], int size) { int x; int y; student *temp = NULL; for(x = 0; x < size; x++) { for(y = 0; y < size-1; y++) { if(array[y]->mean > array[y+1]->mean) { temp = array[y+1]; array[y+1] = array[y]; array[y] = temp; } } } return; } //bubble.h void bubble(student *array[], int size); //student.h typedef struct student_info{ char *first; char *last; int exam1; int exam2; int exam3; float mean; } student; //grades.txt CSCE1040 Erica Sanders 75 89 67 Kelley Cummings 74 70 79 Jamie Reynolds 64 52 66 Shawna Huff 80 88 61 Muriel Holmes 81 74 79 Marion Harmon 77 64 69 Catherine Moss 51 80 73 Kristin Fernandez 86 69 81 Elsa Alvarado 63 77 67 Cora Spencer 76 79 71 Valerie Olson 85 78 79 Anne Singleton 85 87 65 Rene Boone 85 85 77 James Morgan 69 86 51 Cedric Haynes 72 73 88 Elijah Snyder 65 92 91 Roger Howard 79 95 71 Archie Black 70 81 63 Melvin Watkins 66 67 72

The correct way to compile your C++ files is by omitting the header files and any other non-source files like grades.txt in the g++ command. Just include the .cpp files. The header files will be automatically included by the preprocessor as specified in the #include directives.
Compile using:
g++ studentMain.cpp bubble.cpp -o output
