Basic for Loop in C
- 1. FOR LOOP A presentation by: ROHIT SONI & SACHIN SHARMA
- 2. Iteration Statements ■ Used to iterate or re-use a set of instructions ■ Saves programming time ■ Reduce number of lines of code ■ Ultimately makes a program more efficient Iteration Statements For Loop While Loop Do-While Loop
- 3. Iteration Statements ■ Iteration Statements have three part: – Initialization – Condition – Increment/Decrement Initialization: Initializes the loop variable. Condition: The loop will execute till the condition is met. Increment/Decrement: It alters the value of the loop variable.
- 4. FOR Loop ■ It is a entry control loop i.e. the condition is checked before executing the loop statements ■ It is used to iterate a set of lines/instructions ■ Initialization, Condition and Increment/Decrement all resides together at the top of the statement ■ Mostly used while working with arrays or while printing some patterns
- 5. FOR loop – SYNTAX for ( initialization; condition; increment_or_decrement ) { //Set of instructions to be iterated }
- 6. Different cases in FOR loop 1. If increment/decrement or condition is missing from the loop, It will run infinitely 2. Initialization can be done outside (above) the loop too.
- 7. Different cases in FOR loop 3. Another way to start infinite loop 4. Semicolon in front of for loop statement: Loop executes but didn’t take any statements under it. i.e. Empty loop will run
