How to make a character move 100cm when a key is pressed?

Hi, I want to make the first person character move forward 100 cm when a key is pressed.
Also, I want it to rotate 90 degrees clockwise when another key is pressed.
I am using the first person template in C++.
Any help in C++ or Blueprint will be great.

Hello reward,

I will assume you have already setup your keys in Project Settings → Input.

Your character class should look something like this:

UCLASS()
class AMyCharacter : public ACharacter
{
    GENERATED_BODY()

private:

    void OnRotateInput();

    void OnMoveInput();

public:

    virtual void SetupPlayerInputComponent(class UInputComponent* InputComponent) override;
};

The implementation of the methods should look as follows:

void AMyCharacter::OnRotateInput()
{
    FRotator CurrentRotation = GetActorRotation();
    CurrentRotation.Yaw += 90.f;
    SetActorRotation(CurrentRotation);
}

void AMyCharacter::OnMoveInput()
{
    SetActorLocation(GetActorLocation() + GetForwardVector() *100)
}

void AMyCharacter::SetupPlayerInputComponent(class UInputComponent* InputComponent)
{
	check(InputComponent);

    InputComponent->BindAction("Move", IE_Pressed, this, &AMyCharacter::OnMoveInput);
    InputComponent->BindAction("Rotate", IE_Pressed, this, &AMyCharacter::OnRotateInput);

}

Cheers,

This assumes your forward vector is X which is not always the case. I prefer something like:
SetActorLocation(GetActorLocation() + (GetActorForwardVector() * 100));

What was I thinking? Of course it has to be the forward vector. Thank you for pointing that out.
