Subject Name: Object Oriented Programming using C++
Subject Code: 21CSH103
EXPERIMENT NUMBER – 1.1
Aim of the practical: WAP to find average marks of five subjects of a student
in a class.
FLOWCHART/ ALGORITHM
Step 1: Start
Step 2: Enter the name of Student.
Step 3: Enter the section of Student.
Step 2: Read the marks of 5 subjects from the user.
Step 3: Find the average using the formula avg = (a+b+c+d+e) / 5.
Step 4: Print the average marks of subject.
Step 5: Stop
PROGRAM CODE
#include<iostream>
using namespace std;
int main()
{
int mark[5], i;
float sum=0;
cout<<"\nEnter marks obtained in Physics, Chemistry, Maths, CS, English :: \n";
for(i=0; i<5; i++)
SUBJECT NAME-Object Oriented Programming using C++ SUBJECT CODE-21CSH103
{
cout<<"\nEnter mark[ "<<i+1<<" ] :: ";
cin>>mark[i];
sum=sum+mark[i];
}
float avg=sum/5;
float perc;
perc=(sum/500)*100;
cout<<"\nAverage Marks of 5 Subjects = [ "<<avg<<" ] \n";
cout<<"\nPercentage in 5 Subjects = [ "<<perc<<"% ] \n";
return 0;
}
ERRORS ENCOUNTERED DURING PROGRAM’S EXECUTION
(Kindly jot down the compile time errors encountered)
1. Interchange of Insertion and Extraction operator.
SUBJECT NAME-Object Oriented Programming using C++ SUBJECT CODE-21CSH103
PROGRAMS’ EXPLANATION (in brief)
First of all, we have to include the header file <bits/stdc++.h> to use the input(cin) and
output(cout) functions.
Further we have to enter a student’s name and section then we have to enter the marks of 5
subjects from the user using cin function and display their Average using the formula avg =
(a+b+c+d+e)/5.
So, after calculating the Average, we print the result on the output screen using cout
function.
OUTPUT
EXPERIMENT NUMBER – 1.2
Aim of the practical: Write a program to swap first and last digit of any
number
FLOWCHART/ ALGORITHM
SUBJECT NAME-Object Oriented Programming using C++ SUBJECT CODE-21CSH103
1. Start the program.
2. Creating a header file for input output stream.
3. Declaration of function for mathematical operations.
4. Function that returns integer value.
5. Print the message and accept the input from the user.
6. Extraction of digits using mathematical operations.
7. Print the message and value after swapping.
8. End the program by returning an integer value.
PROGRAM CODE
#include<iostream>
#include<cmath>
using namespace std;
int main()
int number, firstDigit, lastDigit, count, SwapNum;
cout << "\nPlease Enter Any Number to find First and Last Digit = ";
cin >> number;
count = log10(number);
firstDigit = number / pow(10, count);
SUBJECT NAME-Object Oriented Programming using C++ SUBJECT CODE-21CSH103
lastDigit = number % 10;
SwapNum = lastDigit;
SwapNum = SwapNum * (round(pow(10, count)));
SwapNum = SwapNum + number % (int)(round(pow(10, count)));
SwapNum = SwapNum - lastDigit;
SwapNum = SwapNum + firstDigit;
cout << "\nThe First Digit in a Given Number = " <<firstDigit;
cout << "\nThe Last Digit in a Given Number = " << lastDigit;
cout << "\nAfter Swapping First and Last Digit = " << SwapNum;
return 0;

ERRORS ENCOUNTERED DURING PROGRAM’S EXECUTION
(Kindly jot down the compile time errors encountered)
NO ERRORS
PROGRAMS’ EXPLANATION (in brief)
In this program we have to accept the number from the user and swap the first and last
digit using extraction of digits by mathematical operation and print the message and number
after swapping.

EXPERIMENT NUMBER – 1.3
Aim of the practical: WAP to generate the Fibonacci series up to user
specified limit. Write all the missing terms (e.g. 4, 6, 7, 9, 10, 11, 12, 14, 15…)
also at the end.
FLOWCHART/ ALGORITHM
1. Start the program.
2. Creating a header file for input output stream.
3. Define the context on which name s are defined.
4. Function that returns integer value.
5. Declaration of variables in integer datatype.
6. Print the message and accept the input from the user.
7. Loop is used to enter the terms of Fibonacci series.
8. Check the condition using if else statement and print the message according to it.
9. Print the message and loop is used to find the missing values of series and print it.
10. End the program by returning an integer value.
