Done in the C language. FULL CODE NEEDED SORRY as a back up if my own does not work.. Program is a gradebook. Instructions are below along with example code. Im working on it by myself too but this seems real spooky for an introductory class. DUE AT MIDNIGHT

EXAMPLE CODE

#include

typedef struct FullNameType {

char fname[51];

char lname[51];

struct FullNameType *next;

} FullNameType;

void swapPointers(char **p1, char **p2) {

char *tmp;

tmp = *p1;

*p1 = *p2;

*p2 = tmp;

}

void forceLowercase(char *s) {

for(int i=0; s[i]!=0; i++ ) {

if ( 'A'

s[i] = s[i] + 32;

}

}

}

int strcmp_ci(char *str1, char *str2) {

char tmp1[51], tmp2[51];

strcpy(tmp1,str1);

strcpy(tmp2,str2);

forceLowercase(tmp1);

forceLowercase(tmp2);

return strcmp(tmp1,tmp2);

}

int main(int argc, char **argv) {

int i,j,howMany;

int arraySize = 4;

FullNameType *nameListFirst, *nameListLast;

FullNameType *newFullName, *tmp, *before, *after;

FILE *inputNamesFile, *outputFile;

nameListFirst = NULL;

nameListLast = NULL;

inputNamesFile = fopen(argv[1],"r");

if ( inputNamesFile != NULL ) {

i = 0;

while ( ! feof(inputNamesFile) ) {

newFullName = malloc( sizeof(FullNameType) ); // allocate an "instance" of the structure

// should do bulletproofing to check whether malloc succeeded...

(*newFullName).next = NULL;

fscanf(inputNamesFile,"%50s %50s", (*newFullName).fname, (*newFullName).lname );

// inserting at the bottom of the list....

if (nameListLast != NULL) {

nameListLast->next = newFullName;

nameListLast = newFullName;

} else {

nameListFirst = newFullName;

nameListLast = newFullName;

}

i++;

}

// From this point can do other things with the list... insert, delete, edit, save file, and so forth

} else {

printf("File %s not found!! ", argv[1]);

}
