Function Parameter: Function parameters are variables of a function that we can use to send data to the function. Parameters are declared as follows:
function function_name(int var_a, float var_another){
//do something here
}
Here in the above function var_a and var_another are two parameters of the function called function_name. When making a call to that function as follows
function_name(5, 5.5);
we are sending 5 as the value of var_a and 5.5 as the value of var_another to the function. We can then use these two variables inside the function to generate result as per the need.
