typedef struct {
   int num;
   char name[25];
} student;

int main(){
   student s1;
      
   //assign the value of 1234 to num in the s1 structure
   //assign the value of Bob the Builder to name in s1 structure
  
   //display the value of num in the s1 structure
   //display the value of name is the s1 structure

student *s2;
      
   //assign the value of 7754 to num in the s2 structure
   //assign the value of Bullwinkle to name in s2 structure
  
   //display the value of num in the s2 structure
   //display the value of name is the s2 structure

  
   return 0;
}//end main()

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

typedef struct {
   int num;
   char name[25];
} student;

int main(){
   student s1;
      
   //assign the value of 1234 to num in the s1 structure
   s1.num = 1234;
   //assign the value of Bob the Builder to name in s1 structure
   strcpy(s1.name, "Bob the Builder");
   
  
   //display the value of num in the s1 structure
   printf("%d\n",s1.num);
   //display the value of name is the s1 structure
   printf("%s\n",s1.name);

   student *s2 = (student*)malloc(sizeof(student));
      
   //assign the value of 7754 to num in the s2 structure
   s2->num = 7754;
   //assign the value of Bullwinkle to name in s2 structure
   strcpy(s2->name, "Bullwinkle");
  
   //display the value of num in the s2 structure
   printf("%d\n",s2->num);
   //display the value of name is the s2 structure
   printf("%s\n",s2->name);
