Coding Question on meeting two conditions

Projects Programming
1

I would like to know how to modify the code listed below to proceed only if two conditions are met. For example both voltage and light to be present before continuing to the next part of the loop. Maybe a double IF statement? or an IF & AND statement?
I am a novice coder with limited understanding so any assistance would be appreciated.

Thanks,

Code is listed below:

int light;
int volt;

void setup()
{
pinMode(13, OUTPUT); // put your setup code here, to run once:
pinMode(7, OUTPUT);
Serial.begin(9600);
}

void loop()
{
light = analogRead(A0); // put your main code here, to run repeatedly:
volt = analogRead (A4);

//*********************
if (light < 700)
{
digitalWrite(13, HIGH); // LED on:
digitalWrite(7, HIGH); // Relay on:
}

else
{
digitalWrite(13, LOW); //LED off:
digitalWrite(7, HIGH);
}

//*********************
if (light > 700)
{
digitalWrite(13, LOW);
delay(900000); //15 minute delay:
}

else
{
digitalWrite(13, HIGH);
}

//*********************
if (volt < 500)
{
digitalWrite(13, HIGH);
digitalWrite(7, HIGH);
}

else
{
digitalWrite(7, LOW);
delay(14400000); //4hr delay for battery recharge:
}

//*********************
if (volt > 500)
{
digitalWrite(7, LOW);
digitalWrite(13, LOW);
}

else
{
digitalWrite(7, HIGH);
}

//*********************
Serial.println(light);
delay(100);

} //END of loop()

Your if statement should look like this -

if(light == && volt == ){
Your function to do
}

The parameter refers to the state of the analog pins when you want to run the function.

To check 2 conditions at the same time and run a function when both are true, you need to use && between the two conditions.

You can use and in place of &&. IMHO it makes code easier to read

Thanks guys.
I will implement your suggestions.
I really appreciate the guidance.
