C++ Program tutorials for Operators

C++ Program Arithmetic operators on int variables

Sam Sir

// Program name test013.cpp

// Arithmetic operators on int variables

#include <iostream.h>

void main()

{

int a,b; // declare two variable a and b as integer

a=10;

b=4;

cout<<" a + b = "<<(a+b)<<"\n";

cout<<" a - b = "<<(a-b)<<"\n";

cout<<" a * b = "<<(a*b)<<"\n";

cout<<" a / b = "<<(a/b)<<"\n";

cout<<" a modulus b ="<<(a%b);

}

Output

a + b = 14

a b = 6

a * b = 40

a / b = 2

a modulus b = 2

 

Note:- All though 10/4 should give you 2.5 answer for division operation, but as a and b variable is integer, the result is shown as 2 only.


C++ Program Arithmetic operators on char variables

Sam Sir

// Program name test014.cpp

// Arithmetic operators on char variables

#include <iostream.h>

void main()

{ char V1,V2; // declare two variable V1 and V2 as character

V1='A'; // Assign A to variable V1

V2='S'; // Assign S to variable V2

cout<<"V1 = "<<V1<<" V2 = "<<V2<<"\n";

cout<<"ASCII Value of V1 = "<<(int)V1<<" V2 = "<<(int)V2<<"\n";

cout<<"V1 + V2 = "<<(V1+V2)<<"\n";

cout<<"V1 - V2 = "<<(V1-V2)<<"\n";

cout<<"V1 * V2 = "<<(V1*V2)<<"\n";

cout<<"V1 / V2 = "<<(V1/V2);

}

Output

V1 = A V2 = S

ASCII Value of V1 = 65 V2 = 83

V1 + V2 = 148

V1 V2 = -18

V1 * V2 = 5395

V1 / V2 = 0


Assume i is integer variable with value 10, f is float variable with value 7.5, c is character variable with value 'A'

 

C++ Program Arithmetic operators on mixed variables

Sam Sir

// Program name test015.cpp

// Arithmetic operators on mixed variables

#include <iostream.h>

void main()

{ int i = 10; // declare and assign 10 to integer varaiable i

char c = 'A'; // declare and assign A to character variable c

float f = 7.5; // declare and assign 7.5 to float varaiable f

cout<<"i + f = "<<(float)i+f<<"\n";

cout<<"i + i = "<<i+i<<"\n";

cout<<"i + c = "<<i+c<<"\n";

cout<<"( i + c) - (2 * f /5) = "<<(float)( i + c ) - (2*f/5);

}

Output

i +f = 17.5

i + I = 20

i + c = 75

( i + c) - ( 2 * f / 5) = 72

 


C++ Program for Unary pre and post increment and decrement

Sam Sir

// Program name test016.cpp

// Unary pre and post increment and decrement

#include <iostream.h>

void main()

{ int v1,v2,v3,v4;

v1=v2=5;

v3=v4=10;

cout<<"v1 = "<<v1<<"\n";

cout<<"v1 = "<<v1++<<"\n"; // post increment

cout<<"v1 = "<<v1<<"\n\n";

 

cout<<"v2 = "<<v2<<"\n";

cout<<"v2 = "<<++v2<<"\n"; // pre increment

cout<<"v2 = "<<v2<<"\n\n";

 

cout<<"v3 = "<<v3<<"\n";

cout<<"v3 = "<<v3--<<"\n"; // post decrement

cout<<"v3 = "<<v3<<"\n\n";

 

cout<<"v4 = "<<v4<<"\n";

cout<<"v4 = "<<--v4<<"\n"; // pre decrement

cout<<"v4 = "<<v4;

}

Output

v1 = 5

v1 = 5

v1 = 6

 

v2 = 5

v2 = 6

v2 = 6

 

v3 = 10

v3 = 10

v3 = 9

 

v4 = 10

v4 = 9

v4 = 9
