                                                         While Vs Do-While Loop

Comparison Basis	While Loop	Do-While Loop
Definition	Executes a block of code as long as the condition is true	Executes a block of code at least once, and then repeats as long as the condition is true
Condition Evaluation	Before entering the loop body	After executing the loop body
Execution Guarantee	May not execute if the condition is false initially	Executes at least once regardless of the condition
Syntax	while (condition) { // code }	do { // code } while (condition);
Use Case	When the loop should run only if the condition is initially true	When the loop must run at least once
Initial Check	Condition checked before execution	Condition checked after execution
Example	while (i < 5) { i++; }	do { i++; } while (i < 5);
