In this tutorial, you shall learn about Greater-than Relational Operator in C++ programming language, its syntax, and how to use this operator with the help of examples.

C++ Greater than Operator

In C++, Greater-than Relational Operator is used to check if left operand is greater than the right operand.

The syntax to check if x is greater than y using Greater-than Operator is

</>
Copy
x > y

The operator returns a boolean value of true if x is greater than y, or false if not.

Examples

1. Check if number in x is greater than that of in y

In the following example, we take two integer values in x and y, and check if the value in x is greater than that of y, using Greater-than Operator.

main.cpp

</>
Copy
#include <iostream>
using namespace std;

int main() {
    int x = 5;
    int y = 2;
    
    if (x > y) {
        cout << "x is greater than y." << endl;
    } else {
        cout << "x is not greater than y." << endl;
    }
}

Output

x is greater than y.
Program ended with exit code: 0

Since value in x is greater than that of in y, x > y returned true.

2. Check if string in x is greater than that of in y

Now, let us take two strings, and check if one string is greater than other. By default, strings are compared lexicographically, meaning, whichever the string comes first in a dictionary, that string is lesser.

main.cpp

</>
Copy
#include <iostream>
using namespace std;

int main() {
    string x = "apple";
    string y = "banana";
    
    if (x > y) {
        cout << "x is greater than y." << endl;
    } else {
        cout << "x is not greater than y." << endl;
    }
}

Output

x is not greater than y.
Program ended with exit code: 0

Since value in x is not greater than that of in y, x > y returned false.

In this C++ Tutorial, we learned about Greater-than Operator in C++, with examples.
