The Flow of Sequential Control Structure

The simplest form of control structure - SEQUENTIAL STRUCTURE

In sequential structure, basic I/O program statements are executed one after another, in the order by which they appear in the program. Here is a sample diagram on how linear is the sequential structure is:

The flow of sequential structure diagram shows that the basic flow has its pattern of, first, initialization of variables, followed by the input of data then processing the inputs and all the variables needed (through computation and usage of operators and displaying the final output.

Example Code:

#include <iostream>

using namespace std;

int main() {

//initialization

int num1, num2, prod;

//input

cout << "Enter the first number: ";

cin >> num1;

cout << "Enter the second number: ";

cin >> num2;

//process

prod = num1 * num2;

//output

cout << "Product: " << prod;

return 0;

}

Sample Output:

Enter the first number: 5

Enter the second number: 5

Product: 25
