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