Functions in C++ Programming | Part - 1

Support Simple Snippets by Donations -
--------------------------------------------------------------------------------------------- Definition : A function in C++ is a group of program statements with a unique name that perform a specific task.
Functions are used to provide modularity & reusability to a program.
By default every C++ program execution starts from the main() function.
Depending on whether a function is predefined or created by user; there are two types of function:
Library / Predefined Function
User-defined Function

Syntax of functions:
return_type function_name( parameter list ) {
//body of the function
}

Following are the components of a C++ function:
Return Type: A function may return a value. The return_type is the data type of the value the function returns. Some functions perform operations without returning a value. In this case, the return_type is the keyword void.
Function Name: This is the actual name of the function. The function name and the parameter list together constitute the function signature. To call a function, its name is used.

You got to be kidding me. I've had som struggles with understanding the c++ coding - but you, you have made me not only remember how to do it, but to understand why we are doing this way. Man, you are awesome

[mukthakrishna]

Wow. Honestly, so well explained that I feel like I have now truly understood the concept. Understood it like never before.

I am in college, and I can't believe I'm watching this. Thanks for the awesome refresher man!

1) arraylarge( )
It should find the largest element among an array of size 10. Ask user to input numbers from the user and then find the largest number from it .
2) called( )
This is a function which displays a message that how many times it has been called
e.g “ I am called 3 times “
Design main ( ) in which you have to both the functions several times use argument passing to call the second function . Make variable or arguments whatever you like.
