Program to Find Quotient and Remainder:-

The integer values are used with operators to perform the arithmetic in programming. The divide operation is done in mathematics to get the remainder and quotient value. First, we will take two numbers and divide them to find the quotient and remainder.

With the help of this program, we can take input and Find Quotient and Remainder.

Program to Find Quotient and Remainder:-

#include <iostream>
using namespace std;

int main()
{     
    //declaring the variables for the program to find the quotient and remainder 
    int divisor, dividend, qtnt, rmdr;
    
    //taking input from the user the dividend
    cout << "Enter dividend: ";
    cin >> dividend;
    //taking input from the user the divisor
    cout << "Enter divisor: ";
    cin >> divisor;
    //calculating the quotient for the remainder 
    qtnt = dividend / divisor;
    rmdr = dividend % divisor;
    //Printing the remainder and the quotient after the calculations.
    cout << "Quotient = " << qtnt << endl;
    cout << "Remainder = " << rmdr;

    return 0;
}

#include <iostream>

using namespace std;

int main()

{

//declaring the variables for the program to find the quotient and remainder

int divisor, dividend, qtnt, rmdr;

//taking input from the user the dividend

cout << "Enter dividend: ";

cin >> dividend;

//taking input from the user the divisor

cout << "Enter divisor: ";

cin >> divisor;

//calculating the quotient for the remainder

qtnt = dividend / divisor;

rmdr = dividend % divisor;

//Printing the remainder and the quotient after the calculations.

cout << "Quotient = " << qtnt << endl;

cout << "Remainder = " << rmdr;

return 0;

}

Output:-

In the above program, we have first initialized the required variable.

divisor = it will hold the input number value from the user.
dividend= it will hold the input number value from the user.
qtnt = it will hold the integer value of the Quotient.
rmdr = it will hold the integer value of the Remainder.

Algorithm for the program to view data type size:-

1. Initiating the program

2. Using size of function to print the size of character data type.

3. Using size of function to print the size of integer data type.

4. Using size of function to print the size of float data type..

5. Using size of function to print the size of double data type.

Program to check the size of predefined data types in C++ programming.

In every programming language, there are many predefined datatypes available. Today we will create a program that will print the size of integer, character, float, and double in bytes. Because every datatype variable reserves the size in memory for each type of variable.

With the help of this program, we can find the size of the above data types.

Program:-

/* C++ Program to Find Size of int, float, double and char in Your System */
#include <iostream>
using namespace std;

int main() 
{    
    /* 
    In this program we will show the size of character data type,
    integer data type,float data type,double data type of c++ programming.
    These are the predefined data types in this programming language.
    */
    
    //Printing the size of character data type using size of function.
    cout << "Size of char: " << sizeof(char) << " byte" << endl;
    //Printing the size of integer data type using size of function.
    cout << "Size of int: " << sizeof(int) << " bytes" << endl;
    //Printing the size of float data type using size of function.
    cout << "Size of float: " << sizeof(float) << " bytes" << endl;
    //Printing the size of double data type using size of function.
    cout << "Size of double: " << sizeof(double) << " bytes" << endl;

    return 0;
}

/* C++ Program to Find Size of int, float, double and char in Your System */

#include <iostream>

using namespace std;

int main()

{

In this program we will show the size of character data type,

integer data type,float data type,double data type of c++ programming.

These are the predefined data types in this programming language.

//Printing the size of character data type using size of function.

cout << "Size of char: " << sizeof(char) << " byte" << endl;

//Printing the size of integer data type using size of function.

cout << "Size of int: " << sizeof(int) << " bytes" << endl;

//Printing the size of float data type using size of function.

cout << "Size of float: " << sizeof(float) << " bytes" << endl;

//Printing the size of double data type using size of function.

cout << "Size of double: " << sizeof(double) << " bytes" << endl;

return 0;

}

Output:-

Printing the size of character data type using the size of function.

Integer type printing its size by using sizeof function.

Printing the size of float data type using the size of function.

Printing the size of double data type using the size of function.
