Question

IN C PLEASE

Question 16 A. Consider “inclass2.h” header file. Define a structure which can hold the following student information: id, first name, last name, and gpa. Use appropriate header file guards. ( Max size of first and last name is 20, id is 7 and gpa is double).

B. Consider an array of student struct with the MAX_SIZE 10 and a first name. These will be provided as an input to your function. Write a function/method that using the given inputs prints out the ID for all the students with the same first name. INPUTS: The struct array should be declared and initialized in the main function.

The following students information should be used to initialize the first 5 elements of the array

Mary Robin aaa111 4.0

Ada Thorne bbb222 3.9

Mary Gray ccc333 3.8

Arthur Eden ddd444 3.7

Mary Aslani eee555 3.6

A variable should be declared and initialized with the name “Mary” in the main and should be provided to the function in part B of the question as one of the inputs ( to print out the id of the students with the same first name).

Answer 1

Code:

#include<stdio.h>
// structure student to hold student data
struct student{
char *id;
char *firstname;
char *lastname;
double gpa;
};

// method to print all ids having same first name
void same_first_name(char *name ,struct student arr[10]){
for(int i=0;i<5;i++){
if(arr[i].firstname == name){
  
printf("%s",arr[i].id);
printf("\n");
}
}
  
}
int main(){
  
struct student arr[10];
  
// initializing the data
arr[0].id="aaa111";
arr[0].firstname="Mary";
arr[0].lastname="Robin";
arr[0].gpa=4.0;
arr[1].id="bbb222";
arr[1].firstname="Ada";
arr[1].lastname="Thorne";
arr[1].gpa=3.9;
arr[2].id="ccc333";
arr[2].firstname="Mary";
arr[2].lastname="Grey";
arr[2].gpa=3.8;
arr[3].id="ddd444";
arr[3].firstname="Arthur";
arr[3].lastname="Eden";
arr[3].gpa=3.7;
arr[4].id="eee555";
arr[4].firstname="Mary";
arr[4].lastname="Aslani";
arr[4].gpa=3.6;
  
// variable to hold the name
char *name="Mary";
  
// calling the method to print ids with same firstname as our variable
same_first_name(name ,arr);
return 0;
  
}

#include<stdio.h> // structure student to hold student data struct student{ char *id; char *firstname; char *lastname; double gpa; }; // method to print all ids having same first name void same_first_name(char *name ,struct student arr[10]){ for(int i=0;i<5; i++) { if(arr[i].firstname == name) { printf("%s", arr[i].id); printf("\n"); int main() { struct student arr[10]; // initializing the data arr[0].id="aaa111"; arc[0].firstname="Mary"; arr[o]. lastname="Robin"; arr[0] .gpa=4.0; arr[1].id="bbb222";

arr[1].firstname="Ada"; arr[1].lastname="Thorne"; arr[1].gpa=3.9; arr[2].id="ccc333"; arr[2].firstname="Mary"; arr[2]. lastname="Grey"; arr[2].gpa=3.8; arr[3].id="ddd444"; arr[3].firstname="Arthur"; arr[3].lastname="Eden"; arr[3].gpa=3.7; arr[4].id="eee555"; arr[4].firstname="Mary"; arr[4].lastname="Aslani"; arr[4].gpa=3.6; e="for thurn arrtam // variable to hold the name char *name="Mary"; // calling the method to print ids with same firstname as our variable same_first_name(name ,arr); return 0;

Output:

aaa111 CCC333 eee555
