Question

Use a struct to define a student entity where its attributes would be: First name, last name, age and the number of completed semesters. You will have an array of pointers for each struct item. You will use the array to navigate through the records. Find the students with the least amount of completed semesters. Conditions: Cannot use Cout or Can, must be written in C.

Answer 1

Main.c
----------------
#include<stdio.h>
#include<malloc.h>
struct student{
char firstName[30];
char lastName[30];
int age;
int semestersCompleted;
  
}*ptr[10];
int main()
{
  
int i;
printf("Enter the Student Details : ");
for(i=0;i<2;i++)
{
ptr[i] = (struct student *) malloc(sizeof(struct student));
printf("\nEnter the Student's First Name : ");
scanf("%s",&ptr[i]->firstName);
printf("\nEnter the Student's Last Name : ");
scanf("%s",&ptr[i]->lastName);
printf("\nEnter the Student's age : ");
scanf("%d",&ptr[i]->age);
printf("\nEnter the count of semester completed : ");
scanf("%d",&ptr[i]->semestersCompleted);
}
printf("\nStudent Details are : ");
int leastSemesterCount = ptr[0]->semestersCompleted;
  
for(i=0;i<2;i++)
{
printf("\n First Name : %s",ptr[i]->firstName);
printf("\n Last Name : %s",ptr[i]->lastName);
printf("\n Age : %d",ptr[i]->age);
printf("\n semestersCompleted : %d",ptr[i]->semestersCompleted);
if(ptr[i]->semestersCompleted < leastSemesterCount){
leastSemesterCount = ptr[i]->semestersCompleted;
}
}
  
printf("\n students with the least amount of completed semesters : %d \n",leastSemesterCount);
return(0);
}
---------------- End------------------------

Output

Description

-----------------

Please make understanding on output first where program takes input as student records and then display the same students details with least seamester completed count.

Let me know if you need more assistence on above program.
