Answer 1

Return in CPP actually means the end result of a particular function so as to be used in other part of the program. functions takes in parameters to return a result.

Lets take for example a blender. A blender has a function in the kitchen. When you put tomatoes "parameter" switch on d blender and when you turn it off, you will get grinded tomatoes "return".

if you put in apples, bananas, oranges, strawberries and mangoes "parameters" into a blender. when switched on for some minutes and switched off, you will get in return a smoothie juice.

int blender (apples, mangoes, bananas)
{
int smoothie;

int apples = 3, mangoes = 5, bananas = 2;

smoothie = apples + mangoes + banana;

return smoothie;
}

NB: Explained just for real world understanding ..
