String Element of Struct not retaining assigned value

I'm having a bit of a bizarre issue with C.

I have a .c file implementing a structure, and another using it. The structure in question is basic info about a student (name and grade). The Implementation file has the functions

• initialize
• read name
• read grade
• free memory (delete instance)

the main file goes as follows:

int main (void){ char inBuff[30]; char* name = NULL; int grade; Student Stu; printf("main: Please enter the name\n"); fgets(inBuff, 30, stdin); name = malloc((sizeof(char)+1)*strlen(inBuff)); strncpy (name, inBuff, 20); printf("main: Please enter the grade\n"); scanf("%d", &grade); InitializeStudent (name, grade, &Stu); /*value testing*/ printf("main: %s\n", Stu.name); printf("main: %d\n", Stu.grade); printf ("main: The student's name is %s\n", NameOfStudent(Stu)); printf ("main: The student's grade is %d\n", GradeOfStudent(Stu)); FreeStudent(&Stu); free (name); return 0; } 

printf() statements in the InitializeStudent() function seem to show the values being assigned correctly. However, both Stu.name and NameOfStudent(Stu) return ASCII, and Stu.Grade and GradeOfStudent(Stu) return 2675716 (which seems to be a memory address) regardless of input.

Of note is the fact that it has been specified that NameOfStudent() and GradeOfStudent() be pass-by-value rather than using a pointer (ie a copy of the struct should be made and passed in to the functions) and have char* and int return types respectively, whereas InitializeStudent() is passed a pointer and is a void function.

Also possibly important, the name field of Student is initialized as

char name[20]; 

rather than

char* name; 

the Student struct definition is as follows:

#define MAXNAMESIZE 20 typedef struct { char name[MAXNAMESIZE]; int grade; } Student; 

as requested, the code for initialize student is as follows

void InitializeStudent (char *name, int grade, Student *S) { printf ("InitializeStudent: entered initialization\n"); int i = 0; S = malloc (sizeof(Student)); for (i = 0; i< strlen(name); i++) if (name[i] == '\n') name[i] = '\0'; strncpy(S->name, name, 20); S->grade = grade; printf ("InitializeStudent: %s\n", S->name); printf ("InitializeStudent: %d\n", S->grade); }
