#include #include #include #include typedef struct student{ int grade; char* nameID; }student_t; void CreateStudent(student_t* s, int grade, char* nameID){ s->grade = grade; s->nameID = strdup(nameID); } // float ComputeAverageGrade(student_t* class, int sizeOfClass){ assert(sizeOfClass > 0 && "Must have at least 1 student"); float total=0.0f; for(int i=0; i <= 5; i++){ total+= class[i].grade; } return total / sizeOfClass;
please help debuging...
// Fix the bugs so that the report of 5 students grades
// is correct. There should be no memory leaks.
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <assert.h>
typedef struct student{
int grade;
char* nameID;
}student_t;
void CreateStudent(student_t* s, int grade, char* nameID){
s->grade = grade;
s->nameID = strdup(nameID);
}
//
float ComputeAverageGrade(student_t* class, int sizeOfClass){
assert(sizeOfClass > 0 && "Must have at least 1 student");
float total=0.0f;
for(int i=0; i <= 5; i++){
total+= class[i].grade;
}
return total / sizeOfClass;
}
int main(){
// Create our classroom of 5 students
student_t* class = (student_t*)malloc(sizeof(student_t)*5);
for(int i=0; i <5 ; i++){
// Assume all nameID's are "temporary"
CreateStudent(&class[i],90,"temporary");
}
// Storage for students grades
float averageGrade = ComputeAverageGrade(class,5);
printf("Class Average = %f\n\n",averageGrade);
// Manually check our work
for(int i=0; i <=5 ; i++){
printf("Student %d\n",i);
printf("\tGrade: %d\n",class[i].grade);
printf("\tID : %s\n",class[i].nameID);
}
return 0;
}
Bugs needed to be fixed as :
In ComputeAverageGrade, the loop condition should be i < sizeOfClass instead of i <= 5.
In the main function, the loop condition should be i < 5 instead of i <= 5.
The memory allocated by strdup needs to be freed using free at the end of the main function.
The memory allocated by malloc needs to be freed using free at the end of the main function.
