Functions in C++ Lecture 10 Write a C++ program to read three numbers from the user to print their factorial. Function â–ª A function is a collection of statements that performs a specific task. â–ª Also called procedure or methods or subroutine. â–ª A program may be broken up into small manageable functions (divide-and-conquer). â–ª Every C++ program has at least one function, which is main(). Function â–ª Instead of writing one long function that contains all of the statements to solve a problem, several small functions that each solve a specific part of the problem can be written. â–ª These small functions can be executed in the desired order to solve the problem. The program has one long, complex function containing all of the statements to solve a problem. The problem has been divided into smaller problems, each of which is handled by a separate function. #include using namespace std; int main() { cout
