Structured programming paradigms rely on three fundamantal control flows: sequence, selection, and iteration. While selection logic handles decision-making via statements like if and switch, repetitive tasks are managed through iteration constructs. C provides three primary keywords for looping: for, while, and do-while. The For Loop Among the ...

while repeatedly executes a block of code as long as its controlling expression evaluates to a truthy value. The moment the expression becomes falsy, execution continues with the statement immediately following the loop body. Syntax The general form is: while expression: statement(s) The expression is tested before every iteration. If it y ...

A while loop repeatedly executes a block of indented statements as long as its condition evaluates to true. Once the condition becomes false, execution proceeds beyond the loop. counter = 1 # Execute body while counter does not exceed 100 while counter <= 100: print('ok') counter += 1 # Both print and increment share indentation, con ...

Compound Statements A compound statement in Java defines a local scope for variables. Variables declared inside this scope are only accessible within the compound statement itself. public class FlowControlBasics { public static void main(String[] args) { int primaryNum = 15; { int secondaryNum = 30; S ...
