Multiple Choice Questions on Repeating Actions in Computer Science

📚 Quick Study Guide

💡 Repeating actions, also known as loops, are fundamental control flow structures in programming. They allow a block of code to be executed multiple times. 🔄 There are primarily three types of loops: for loops, while loops, and do-while loops. 🔢 For Loop: Used when the number of iterations is known beforehand. Syntax: for (initialization; condition; increment/decrement) { // code to be executed } ⏳ While Loop: Used when the number of iterations is not known beforehand, and the loop continues as long as the condition is true. Syntax: while (condition) { // code to be executed } ⚠️ Do-While Loop: Similar to the while loop, but the code block is executed at least once, regardless of the condition. Syntax: do { // code to be executed } while (condition); 📈 Loop control statements like break and continue can alter the normal flow of a loop. break terminates the loop, while continue skips the current iteration.
