C Language:

my program below is working but there is something wrong. When I run it I have to type something in first before it will pop up and I have to do it each time. I tried everything and nothing work. Also, the names did not list in alphabetical order. You will see what I mean when you run the program. I need the program fix within one hour. Thanks!

//#include //#include //#include #define SIZE 15 /* string length limit, including \0 */ #define LIM 30 /* maximum number of lines to be read */ #define HALT "" /* null string to stop input */

void stsrt2(char *strings[], int num);/* string-sort function */ char * s_gets(char * st, int n); void upperCase(char *);

void roll(void) { int total = 0; /* input count */ int k; /* output count */ char first[LIM][SIZE]; char last[LIM][SIZE]; char *ptstr1[LIM]; char *ptstr2[LIM]; getchar(); printf("Input up to %d student name, and I will sort them. ",LIM); printf("To stop, press the Enter key at a line's start. "); //while (total

printf("Enter First Name: "); s_gets(first[total],SIZE); ptstr1[total] = first[total]; upperCase(first[total]);

printf("Enter Last Name: "); s_gets(last[total],SIZE); ptstr2[total] = last[total]; upperCase(last[total]); total++; } stsrt2(ptstr1, total); stsrt2(ptstr2, total);

printf(" Here are the names: "); for (k = 0; k

/* string-pointer-sorting function */ void stsrt2(char *strings[], int num) { char *temp; int top, seek; for (top = 0; top 0) { temp = strings[top]; strings[top] = strings[seek]; strings[seek] = temp; } }

char * s_gets(char * st, int n) { char * ret_val; int i = 0; ret_val = fgets(st, n, stdin); if (ret_val) { while (st[i] != ' ' && st[i] != '\0') i++; if (st[i] == ' ') st[i] = '\0'; else // must have words[i] == '\0' while (getchar() != ' ') continue; } return ret_val; }

void upperCase(char * str) { while (*str) { *str = toupper(*str); str++; } }

Create a program that prints a class roll sheet in alphabetical order. The user inputs the students' first name and last names (separately!), and presses enter on the first name when done. The program prints out the roster like this... HATFIELD, HEIDI KAISER, RUSSELL LIPSHUTZ, HOWARD PENKERT, DAWN WRIGHT, ELIZABETH
