Conditionals condition ? actionA : actionB # equivalent multi-branch form: if (cond1) { stmt1 } else if (cond2) { stmt2 } else { stmt3 } Looping Constructs While loop: while (cond) statement Do-while loop: do statement while (cond) For loop: for (init; test; step) statement Filter Lines by Field Val...
Shell scripts provide several loop mechanisms for repetitive task automation. This guide covers the main loop types available in Bash. Loop Types Overview Loop Type Purpose for Iterate over a list or sequence while Execute while a condition is true until Execute until a condition becomes true select...
C is a structured programming language built upon three fundamental patterns: sequential execution, selection, and repetition. The language provides dedicated constructs for each pattern. Selection is implemented through if and switch, while repetition is handled by for, while, and do while. A state...
Using continue in for Loops The continue statement skips the remaining code in the current iteration and jumps directly to the next one. In a for loop, this means moving to the next element immediately. Printing only multiples of 3 from a range: for num in range(1, 21): if num % 3 != 0: continue pri...
I. Classification of Loops while loop for-in traversal loop II. The while Loop 1. Syntax of while while condition: # loop body 2. Difference Between if and while if evaluates the condition once; if true, executes the block once. while evaluates the condition n+1 times; if true, executes the block n...
While Loop Implementation print("-" * 10 + "Class Attendance Check" + "-" * 10) response = input("Do you have class today? y/n") # Initialize variable while response == "y": # Condition check print("Class is required") response = input(&quo...
Conditional Statements: if Execute code block 'a' if condition A is met, otherwise execute code block 'b'. This control flow is called a condisional statemant. Basic Example age = 20 if age >= 18: print("Adult") else: print("Minor") Multi-Condtiion Example score = 75 if score...
Switch Statements Purpose Primarily used for equality comparisons against multiple values. Syntax switch(variable) { case value1: // code block break; case value2: // code block break; default: // default code block break; } Key notes: Default block is optional Break statemants exit the switch block...
The break keyword serves as a control flow mechanism that immediately terminates the execution of the innermost enclosing for, while, do-while, or switch block. It is primarily utilized to halt iteration prematurely when a specific condition is met or to prevent fall-through behavior in switch const...
Codnitional Branching Range-based decisions utilize if-else ladders: const temperature = 28; if (temperature >= 30) { console.log("Hot weather: Use air conditioning"); } else if (temperature >= 20) { console.log("Mild weather: Open windows"); } else if (temperature >= 10...
