Arithmetic Expression

Relation Expression in C++ 

A condition or logical expression is an expression that can only take the values true or false. The operands in a relational expression can be arithmetic or character string expressions.  When logical fields  are compared, a logical one ('1') is greater than logical zero ('0'). Symbolically, this is ('1' > '0'). The following is an example of a relational expression (x < y). It takes the value true if the value of the variable x is less than the value of the variable y.

Example: (a>b), (a==b), (a<=b), (a>=b) etc.

1. Write a C++ program to define the Arithmetic Expression.

#include<iostream>

using namespace std;

int main()

{

int x, y, result;

cout<<"Enter the values of x, y : ";

cin>>x>>y;

result = (x<y) ? x : y;

cout<<"The result of the above expression is : "<<result;

return 0;

} 

Explanation: In the above program we are using relational expression ( the set of operators and operands) like result= result = (x<y) ? x : y; it is also the ternary expression.

Note: This program output is tested on www.jdoodle.con

Output:

Enter the values of x, y, z and a : 2  3

The result of the above expression is : 2

2. Write a C++ program to define the Arithmetic Expression using user defined function.

#include<iostream>

using namespace std;

int relational_exp( int, int);

int main()

{

int x, y, result;

cout<<"Enter the values of x, y : ";

cin>>x>>y;

result = relational_exp(x, y);

cout<<"The result of the above expression is : "<<result;

return 0;

} 

int relational_exp( int x, int y)

{

return (x<y) ? x : y ;

}

Explanation: In the above program we are using relational expression ( the set of operators and operands) like result= result = (x<y) ? x : y; it is also the ternary expression in a user  defined function relational_exp() which takes two argument in it. 

Note: This program output is tested on www.jdoodle.con

Output:

Enter the values of x, y, z and a : 12 10 

The result of the above expression is : 10
