Programming’s core concept of control structures gives you the ability to manage a program’s flow of execution. Most programming languages contain one of three fundamental control structures:
1. Statements with conditions:
With conditional statements, you can run certain code blocks in response to a given condition. “If” and “if-else” statements are the two most used forms of conditional statements.
Example:
int x = 10;
if (x > 5) {
System.out.println(“x is greater than 5”);
} else {
System.out.println(“x is less than or equal to 5”);
}
2. Circles:
With loops, a block of code can be run repeatedly until a particular condition is satisfied. The two most popular kinds of loops are “while” and “for” loops.
Example:
for (int i = 1; i <= 5; i++) {
System.out.println(“Iteration: ” + i);
}
3. Uses:
Code snippets can be contained within reusable units using functions. Functions can be defined with particular input parameters and return values.
Example:
int add(int a, int b) {
return a + b;
}
int result = add(3, 4);
System.out.println(“Result: ” + result);
Writing organised and effective code requires an understanding of these fundamental control structures.
