Question

Q 1.

Complete the function createStudent below: #include <stdio.h> #include <stdlib.h> struct student { char name[50]; int age; struct student *next; }; struct student * createStudent(char studentName[], int studentAge) { } int main() { struct student *studptr; int myAge; char myName[50]; scanf("%s %d", myName, &myAge); studptr = createStudent(myName, myAge); printf("Student %s is %d years old.\n", studptr->name, studptr->age); free(studptr); return 0; }

Q 2.

if it works, I'll thumb up for u.

Answer 1

Q1. code:

#include<stdio.h>
#include<stdlib.h>
struct student {
char name[50];
int age;
struct student *next;
};
struct student * createStudent(char studentName[], int studentAge)
{
struct student *temp = (struct student *)malloc(sizeof(struct student)); //creating empty node to store the student details.
strcpy(temp->name, studentName); //copying student name into structure name variable.
temp->age = studentAge; //copying student age into structure age variable.
temp->next = NULL; //storing reference next variable to null.
return temp; //returning created node to main function.
}
int main()
{
struct student *studptr;
int myAge;
char myName[50];
scanf("%s %d", myName, &myAge);
studptr = createStudent(myName, myAge);
printf("Student %s is %d years old.\n", studptr->name, studptr->age);
free(studptr);
return 0;
}

Image of code:

#include<stdio.h> #include<stdlib.h> Estruct student { char name (50); int age; struct student *next; -}; struct student * createStudent (char studentName[], int studentAge) struct student *temp = (struct student *) malloc(sizeof(struct student)); //creating empty node to store the student details. strcpy(temp->name, studentName); // copying student name into structure name variable. temp->age = studentAge; // copying student age into structure age variable. temp->next = NULL; // storing reference next variable to null. return temp; //returning created node to main function. int main() 14 15 16 17 18 19 20 21 22 23 24 25 26 struct student *studptr; int myAge; char myName [50]; scanf("%s 3d", myName, AmyAge); studptr = createStudent (myName, myAge); printf("Student ts is $d years old. \n", studptr->name, studptr->age); free (studptr); return 0;

output:
