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.

Loops in C Programming Language
- 1. Prepared By Mahantesh S. Devoor
- 2. Content Objective Introduction Types of looping while do-while for Assessment metric Conclusion References
- 3. Course Objective Understand the 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 Understand the basics of looping. To use the while, do-while and for repetition statement to execute statements in a program repeatedly.
- 5. INTRODUCTION Statements in a 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 statements are 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 It has 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>; }
- 11. do…while Loop Do while 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 loop has 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
- 16. ASSESSMENT METRIC What is 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 of loops 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.
