Nerd homework

[Monticore]

My son needs help with his homework and I know nothing about coding , he is trying to get a RGB strip to light up with increasing intensity as more pressure is applied to sensor while also randomizing a series of colors .(llike a light up shoe)

this is what he has which he knows is horribly wrong i am pretty sure this is C/C+, this is his hisrt ever coding class so his knowledge is fairly limited.
I also know it is in french but it might still make sense to some of you

int valeur1 = 0; //variable de type integer pour enregistrer analog A0
int valeur2 = 0; //variable de type integer pour enregistrer analog A0
int valeur3 = 0;
int valeur4 = 0;
int valeur5 = 0;

void setup() {

Serial.begin(9600); //commence le serial pour ecrire les données
pinMode(A0,INPUT_PULLUP); //prepare A0 pour le pressure sensor
pinMode(3,OUTPUT); //prepare pin 3 pour output de 5V
pinMode(5,OUTPUT);
pinMode(6,OUTPUT);
}

void loop() {

valeur1 = analogRead(A0);
delay(1000);
valeur2 = (200/valeur1);
valeur3 = (valeur2*valeur2);




valeur4 = random(255);
valeur5 = valeur4;

if (valeur4 > valeur5){
valeur5--;
analogWrite(3,valeur5);

}

if (valeur4 < valeur5){
valeur5++;
analogWrite(3,valeur5);

}

if (valeur4 == valeur5){

valeur5;
analogWrite(3,valeur5);

}







if (valeur4 > valeur5){
valeur5++;
analogWrite(5,valeur5);

}

if (valeur4 < valeur5){
valeur5--;
analogWrite(5,valeur5);

}

if (valeur4 == valeur5){

analogWrite(5,valeur5);

}








if (valeur4 > valeur1){
valeur5++;
analogWrite(6,valeur5);

}

if (valeur4 < valeur5){
valeur5--;
analogWrite(6,valeur5);

}

if (valeur4 == valeur5){

analogWrite(6,valeur5);

}

}

would appreciate any help or insults
