String Functions


Complete the following program.  Add code to

  1. prompt for and accept the names of a several students
  2. accept "^" as a signal to end the name input process
  3. display the names in sorted order

Note that the sort function provided below. 

 // String Functions
 //
 #include <stdio.h>
 #include <string.h>
 #define MAX_STUDENTS 5
 #define MAX_LETTERS 30
 void bubble(char [][MAX_LETTERS+1], int);

 int main(void)
 {
         int noStudents;
         char student[MAX_STUDENTS][MAX_LETTERS+1]; 

























         return 0;
 }

 void bubble(char a[][MAX_LETTERS+1], int size)
 { 
         int i, j;
         char temp[MAX_LETTERS+1];

         for (i = size - 1; i > 0; i--) {
                 for (j = 0; j < i; j++) {
                         if (strcmp(a[j],a[j+1]) > 0) {
                                 strcpy(temp, a[j]);
                                 strcpy(a[j], a[j+1]);
                                 strcpy(a[j+1], temp);
                         }
                 }
         }
 }

Compare your answers with those of one of your collegues and make sure that the two of you agree.
