What are if then statments .Ill need examples please .its for a project .

An if/then statement is of the form:

If A is true, then B is also true.

An example would be:
If today is Wednesday, then tomorrow is Thursday.

Surely you can think of others.

A geometry example of an if/then statement would be:

If two sides and the included angle of a pair of triangles are equal, then the triangles are congruent.

If-then statements, also known as conditional statements, are a fundamental concept in programming and logical reasoning. They allow you to specify a condition and define the actions that should be taken based on whether that condition is true or false. In most programming languages, if-then statements are written using the syntax "if(condition){ action }".

Here are a few examples of if-then statements:

Example 1:
```
if (x > 5) {
print("x is greater than 5");
}
```
In this example, if the variable `x` is greater than 5, the statement inside the curly braces will be executed and "x is greater than 5" will be printed.

Example 2:
```
if (temperature < 0) {
turnOnHeating();
} else {
turnOnCooling();
}
```
In this example, if the temperature is below 0, the `turnOnHeating()` function will be called. Otherwise, the `turnOnCooling()` function will be called.

Example 3:
```
if (score >= 90) {
grade = 'A';
} else if (score >= 80) {
grade = 'B';
} else if (score >= 70) {
grade = 'C';
} else {
grade = 'F';
}
```
In this example, the grade will be determined based on the score. If the score is 90 or higher, the grade will be 'A'. If the score is between 80 and 89, the grade will be 'B', and so on. If none of the conditions are met, the grade will be 'F'.

To implement if-then statements in your project, you can use the programming language of your choice and modify the conditions and actions according to your project requirements.
