Sequence

L1

This page is under construction. Please come back later.

In programming languages we have three ways to control the flow of statements: Sequence, Selection and Iteration. Sequence is the simplest and most basic flow control mechanism. It simply means that statements are executed sequentially in the order they appear in the program.

Sequence1.cpp
#undef NDEBUG

#include <iostream>
#include <string>

using namespace std;

int main(int argc, char **argv) {
	int x = 1;
	cout << "x: " << x << endl;
	x = 2;
	cout << "x: " << x << endl;
	x = 3;
	cout << "x: " << x << endl;
	return 0;
}
Output
$ g++ -std=c++17 Sequence1.cpp -o Sequence1 -lfmt $ ./Sequence1 x: 1 x: 2 x: 3
cpp
