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

## C++ Less than or equal to

In C++, Less than or equal to Relational Operator is used to check if left operand is less than or equal to the second operand.

The syntax to check if `x` is less than or equal to `y` is

`x <= y`

The operator returns a boolean value of `true` if `x` is less than or equal to `y`, or `false` if not.

## Examples

### 1. Check if number in x is less 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 less than or equal to that of in `y`, using Less than or equal to Operator.

main.cpp

```#include <iostream>
using namespace std;

int main() {
int x = 5;
int y = 9;

if (x <= y) {
cout << "x is less than or equal to y." << endl;
} else {
cout << "x is not less than or equal to y." << endl;
}
}```

Output

```x is less than or equal to y.
Program ended with exit code: 0```

Since value in `x` is less than or equal to that of in `y`, `x <= y` returned `true`.

### 2. Check if string in x is less than or equal to that of in y

Now, let us take two strings, and check if one string is less than or equal to the other. By default, strings are compared lexicographically.

main.cpp

```#include <iostream>
using namespace std;

int main() {
string x = "mango";
string y = "banana";

if (x <= y) {
cout << "x is less than or equal to y." << endl;
} else {
cout << "x is not less than or equal to y." << endl;
}
}```

Output

```x is not less than or equal to y.
Program ended with exit code: 0```

Since value in `x` is not less than or equal to that of in `y`, `x >= y` returned `false`.

## Conclusion

In this C++ Tutorial, we learned about Less than or equal to Operator in C++, with examples.
