Question

write a program that initializes an integerarray of 8 elements representing the ID numbers of 8students, then inputs a value for an ID to be searched for inthe array output the position of that ID in the array if found,or asuitable message if not.

Answer 1

#include <iostream>

using namespace std;

int main() {

int student_id[8]={5,76,23,56,34,67,12,455};

int i,id_s;//i iterator,id_s for search.

cout<<"Enter the id to be searched"<<endl;

cin>>id_s;//taking input of the id to be searched..

bool b=false;

for(i=0;i<8;i++)

{

if(student_id[i]==id_s)

{

cout<<"Position of the id is "<<i<<endl;//printing the position if found..

b=true;

break;

}

}

if(b==false)//if element is not present printing the message..

cout<<"The student does not exists"<<endl;

return 0;

}

Output:

Enter the id to be searched

76

Position of the id is 1

Enter the id to be searched

87

The student does not exists

Step-by-step explanation:

I have taken a array of size 8 for eight students.Iterating over the array if the id is found then printing the position if not found then printing the message.
