In this tutorial, you shall learn about Greater-than or Equal-to Relational Operator in C++ programming language, its syntax, and how to use this operator with the help of examples.
C++ Greater than or equal to Operator
In C++, Greater than or equal to Relational Operator is used to check if left operand is greater than or equal to the second operand.
The syntax to check if x
is greater than or equal to y
is
x >= y
The operator returns a boolean value of true
if x
is greater than or equal to y
, or false
if not.
Examples
1. Check if number in x is greater than or equal to 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 or equal to that of in y
, using Greater than or equal to Operator.
main.cpp
#include <iostream> using namespace std; int main() { int x = 5; int y = 2; if (x >= y) { cout << "x is greater than or equal to y." << endl; } else { cout << "x is not greater than or equal to y." << endl; } }
Output
x is greater than or equal to y. Program ended with exit code: 0
Since value in x
is greater than or equal to that of in y
, x >= y
returned true
.
2. Check if string in x is greater than or equal to that of in y
Now, let us take two strings, and check if one string is greater than or equal to the other. By default, strings are compared lexicographically.
main.cpp
#include <iostream> using namespace std; int main() { string x = "apple"; string y = "banana"; if (x >= y) { cout << "x is greater than or equal to y." << endl; } else { cout << "x is not greater than or equal to y." << endl; } }
Output
x is not greater than or equal to y. Program ended with exit code: 0
Since value in x
is not greater than or equal to that of in y
, x >= y
returned false
.
Conclusion
In this C++ Tutorial, we learned about Greater than or equal to Operator in C++, with examples.
