Subtract two numbers in C++ programming
In this article, we will discuss the concept of the Subtract two numbers in C++ programming
In this post, we are going to learn how to write a program to find the subtraction of two numbers in C++ programming language
Subtract two integer numbers
The program use to find subtraction of given two integer numbers
Program 1
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int num1=366,num2=189;
//variable declaration
int sub=num2-num1;
//formula of subtraction
cout<<"Differences of two numbers are: "<<sub;
//display the result
getch();
return 0;
}
When the above code is executed, it produces the following result
Differences of two numbers are: -177
Subtract two integer numbers using user input
This program allows the user to enter two integer numbers Then the program find the subtraction of the given two number
Program 2
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int num1,num2;
//variable declaration
cout<<"Enter two integer for subtract: ";
cin>>num1>>num2;//read the inputs
int sub=num2-num1;
//formula of subtraction
cout<<"Differences between two numbers are: "<<sub;
//display the result
getch();
return 0;
}
When the above code isexecuted, it produces the following result
case 1
Enter two integer for subtract: 456 567 Differences between two numbers are:111
case 2
Enter two integer for subtract: 567 456 Differences between two numbers are:-111
Subtract two float numbers
The program use to find subtraction of given two float numbers
Program 3
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
float num1=544.567,num2=767.324;
//variable declaration and initialization
float sub=num2-num1;
//formula of subtraction
cout<<"Differences between two numbers are: "<<sub;
//display the result
getch();
return 0;
}
When the above code isexecuted, it produces the following result
Differences between two numbers are:222.757
Subtract two float numbers using user input
This program allows the user to enter two float numbers Then the program find the subtraction of the given two number
Program 4
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
float num1,num2;
//variable declaration and initialization
cout<<"Enter two float numbers: ";
cin>>num1>>num2;//read the inputs
float sub=num2-num1;
//formula of subtraction
cout<<"Differences of two numbers are: "<<sub;
//display the result
getch();
return 0;
}
When the above code isexecuted, it produces the following result
case 1
Enter two float numbers: 123.456 234.567 Differences between two numbers are:111.111
case 2
Enter two float numbers : 234.567 123.456 Differences between two numbers are:-111.111
