In academic institutions, extensive data analysis is conducted, with the findings applied to organizational management. The university management system maintains current records of various colleges, their diverse academic disciplines, and the department responsible for overseeing examinations and results. The project outcome includes structured menus and submenus, enhancing its organized layout.
The object-oriented framework supporting the University Management System is developed using the C++ coding language. This system primarily oversees the assortment of colleges affiliated with the university and the wide array of educational programs they offer. Moreover, the project incorporates a robust menu interface to oversee and oversee the examination and results sections effectively.

bool operator == (student a)
{
if(reg==a.reg)
return true;
else
return false;
}
};
vector <student>v;
The code snippet above is designed to define a class for students, incorporating data variables such as ```
include<iostream>
include<vector>
include<stdio.h>
include<cstring>
include<fstream>
include<algorithm>
using namespace std;
int search_reg(long int reg, int &i);
void get_file
{
student x;
int i=0;
fstream f;
f.open("College.txt",ios::in);
if(f)
{
f.read((char *) &x,sizeof(class student));
while(!f.eof)
{
v.push_back(x);
f.read((char *) &x,sizeof(class student));
}
}
else
;
f.close;
}
The aforementioned code snippet retrieves the file named college.txt.
void bubblesort
{
int i,j;
student x;
for(i=0;i<v.size;i++)
for(j=0;j<v.size-i-1;j++)
if(v[j].reg>v[j+1].reg)
{
x=v[j];
v[j]=v[j+1];
v[j+1]=x;
}
}
The code above is designed to arrange the students' records using a bubble sort technique, resulting in a time complexity of O(n^2).
void bubblesort
{
int i,j;
student x;
for(i=0;i<v.size;i++)
for(j=0;j<v.size-i-1;j++)
if(v[j].reg>v[j+1].reg)
{
x=v[j];
v[j]=v[j+1];
v[j+1]=x;
}
}
The code snippet above is designed to add fresh information into the database of college students.
void bubblesort
{
int i,j;
student x;
for(i=0;i<v.size;i++)
for(j=0;j<v.size-i-1;j++)
if(v[j].reg>v[j+1].reg)
{
x=v[j];
v[j]=v[j+1];
v[j+1]=x;
}
}
The code snippet above is responsible for writing the output generated by the bubble sort algorithm applied to the college students' data into the college.txt file.
int search_reg(long int reg, int &i)
{
int ta=0;
for(i=0;i<v.size;i++)
if(v[i].reg==reg)
{
ta=1;
break;
}
return ta;
}
The aforementioned code snippet is utilized to search for a student's registration in the college within the data file specifically designed for student records.
int search_name(char name, vector<int> &vi)
{
int i,ta=0;
for(i=0;i<v.size;i++)
if(strcmp(v[i].name,name)==0)
{
ta=1;
vi.push_back(i);
}
return ta;
}
The aforementioned code snippet is utilized to search for a student's name within the record file specifically designed for that student.
int search_branch(char branch, vector<int> &vj)
{
int i,ta=0;
for(i=0;i<v.size;i++)
if(strcmp(v[i].branch,branch)==0)
{
ta=1;
vj.push_back(i);
}
return ta;
}
The above code will use to search the branch.
void searchandshow
{
int ch,i,ta=0;
char name[80],branch[50];
vector <int>vi;
vector <int>vj;
long int reg;
poi:
cout<<"\n1.Press to search reg no."
<<"\n2.Press to search name"
<<"\n3.Press to search branch";
cin>>ch;
switch(ch)
{
case 1:
cout<<"\nEnter reg no.: ";
cin>>reg;
if(search_reg(reg,i)==1)
v[i].display;
else
cout<<"\nRecord NOT FOUND!!!";
break;
case 2:
cout<<"\nEnter name: ";
fflush(stdin);
gets(name);
if(search_name(name,vi)==1)
{
for(int j=0;j<vi.size;j++)
v[vi[j]].display;
}
else
cout<<"\nRecord NOT FOUND!!!";
break;
case 3:
cout<<"\nEnter branch: ";
fflush(stdin);
gets(branch);
if(search_branch(branch,vj)==1)
{
for(int j=0;j<vj.size;j++)
v[vj[j]].display;
}
else
cout<<"\nRecord NOT FOUND!!!";
break;
default:
cout<<"\nWrong CHOICE!!!";
goto poi;
}
}
void show
{
int i;
for(i=0;i<v.size;i++)
v[i].display;
}
The above code will use to show the result.
void delete_data
{
int i,j;
long int reg;
vector <student>::iterator p=v.begin;
cout<<"\nEnter Reg. no.: ";
cin>>reg;
if(search_reg(reg,i)==1)
{
student x=v[i];
cout<<"\nThe following data is being deleted";
x.display;
p+=i;
v.erase(p,p+1);
}
}
The code snippet above is employed to remove the stored information.
void edit_data
{
int i,j;
long int reg;
vector <student>vi;
cout<<"\nEnter Reg. no.: ";
cin>>reg;
if(search_reg(reg,i)==1)
{
cout<<"\nEnter new data:";
fflush(stdin);
v[i].input;
}
}
The above code will use to edit the data.
int main
{
int i=1;
get_file;
while(i)
{
system("CLS");
cout<<"\t\t\t-----------------------------------------\n";
cout<<"\t\t\t University Management System\n";
cout<<"\t\t\t-----------------------------------------\n";
cout<<"\n\t\t\tEnter <1> to Add new student"
<<"\n\t\t\tEnter <2> to Display all student"
<<"\n\t\t\tEnter <3> to Remove student"
<<"\n\t\t\tEnter <4> to Edit student"
<<"\n\t\t\tEnter <5> to Search student"
<<"\n\t\t\tEnter <0> to Exit\n";
cout<<"\n\n\t\t\tEnter Your Choice:";
cin>>i;
switch(i)
{
case 1 :
insert_new;
break;
case 2 :
show;
break;
case 3 :
