Loops in C Programming Language
The document provides a comprehensive overview of looping concepts in C programming, emphasizing the importance of loops for efficient coding. It covers three types of loops: while, do-while, and for, detailing their syntax and functionality. Additionally, it includes assessment metrics and references for further reading on the topic.

Introduction to objectives, looping types (while, do-while, for), assessment metrics, conclusion, and references.
Understand programming terminology, strengths of C, writing efficient code, and learning new programming languages.
Understand the basics of looping and using statements for repetitive execution.
Statements in programs are executed sequentially, and the need for repetition arises.
Loop statements repeat blocks or statements; distinction between pretest (entry-controlled) and posttest (exit-controlled) loops.
Pretest loops test condition before iterations; posttest loops test after at least one execution.
Introduction to different loop types: while loop, do-while loop, and for loop.
While loop executes based on a pre-condition. If true, statements/block execute zero or more times.
Example of while loop in C; illustrates execution with output showing 'Hello' three times.
Do-while loop tests condition post execution, ensuring at least one iteration occurs.
C example using do-while loop, output demonstrates 'Hello' printed three times.
For loop consists of an initializer, condition, and increment component.
Illustrates the syntax format of a for loop with flow diagram representation.
Demonstrates the for loop with example code and output of 'Hello' repeated three times.
Metrics to evaluate understanding of looping, examples, and differences between loop types.
Emphasis on the importance of loops for effective coding, reducing line counts, and improving readability.

- 1. Prepared By Mahantesh S.Devoor
- 2. Content Objective Introduction Typesof looping while do-while for Assessment metric Conclusion References
- 3. Course Objective Understandthe basic terminology used in computer programming It stresses the strengths of C, which provide students with the means of writing efficient, maintainable, and portable code. write, compile and debug programs in C language. Increase the ability to learn new programming languages OBJECTIVES
- 4. Topic Objective Understandthe basics of looping. To use the while, do-while and for repetition statement to execute statements in a program repeatedly.
- 5. INTRODUCTION Statements ina program are executed one after the other ex: statement 1; statement 2; : statement n; Sometimes, the user want to execute a set of statements repeatedly.
- 6. Loop statementsare used to repeat the execution of statement or blocks. Iteration of a loop: the number of times the body of loop is executed. Two types of loop structure are: Pretest : Entry - controlled loop Posttest : Exit – controlled loop
- 7. Pretest Vs. Posttest Pretest: Condition is tested before each iteration to check if loops should occur. Posttest : Condition is tested after each iteration to check if loop should continue (at least a single iteration occurs). Conditio n Evaluate d Statements false true Conditio n Evaluate d Statements true false
- 8. TYPES OF LOOP while loop do-while loop for loop
- 9. while Loop Ithas a loop condition only that is tested before each iteration to decide whether to continue or terminate the loop. The body of a while loop will execute zero or more times Syntax: while (<condition>){ <statement/block>; }
- 10.
- 11. do…while Loop Dowhile has a loop condition only that is tested after each iteration to decide whether to continue with next iteration or terminate the loop. Syntax: do{ <statement/block>; }while(condition);
- 12. Example: int i=0; do{ Printf (“Hellon”); i++; }while (i<3); Output: Hello Hello Hello Conditio n Evaluate d Statements true false Flow diagram
- 13. for Loop for loophas three parts: Initializer is executed at start of loop. Loop condition is tested before iteration to decide whether to continue or terminate the loop. Increment is executed at the end of each loop iteration.
- 14. Syntax: for( [initialize]; [condition];[incrementor] ) { <statement/block>; } Conditio n Evaluate d initialization Statements increament true false Flow diagram
- 15.
- 16. ASSESSMENT METRIC Whatis looping? List the types of looping. Explain the while loop with an example. Give the difference between while and do-while loops Explain the syntax of for loop with an example List out the difference between while and for loop. And also explain the do-while loop.
- 17. CONCLUSION Importance ofloops in any programming language is immense, they allow us to reduce the number of lines in a code, making our code more readable and efficient.
