• The for loop in C language is used to iterate the statements or a part of the program several times. It is frequently used to traverse the data structures like the array and linked list. • The syntax of for loop in c language is given below: forloop in C 15 for (Expression1; Expression2; Expression3) {codestobeexecuted;}

Example for Loop Over List Given some list (sNode*): for(sNode*p=L;p!=NULL;p=p->next) {printf("%d\n",p->data) ;} • p starts at the beginning of some list • Points to each element in turn • At end of list p is NULL • We drop out of the loop Kurt Schmidt (Skipjack Solutions) C Loops October 23, 202222/26

In computer programming, a loop is a sequence of instructions that is repeated until a certain condition is reached. An operation is done, such as getting an item of data and changing it, and then some condition is checked such as whether a counter has reached a prescribed number.

Example: C program if the ages of Ram, sham and Ajay are input through the keyboard, write a program to determine the youngest of the three #include< stdio.h >

Using loops, we can traverse over the elements of data structures (array or linked lists). The do-while loop continues until a given condition satisfies. It is also called post tested loop. It is used when it is necessary to execute the loop at least once (mostly menu driven programs).

for loop is used to execute a set of statements repeatedly until a particular condition is satisfied. We can say it is an open ended loop.. General format is, In for loop we have exactly two semicolons, one after initialization and second after the condition.

Programming language C contains three statements for looping: while loop: while loop construct contains the condition first. If the condition is satisfied, the control executes the statements following the while loop else, it ignores these statements. The general form of while loop is: while(condition) { statement1; statement2; ....

Abstract :- In this work, we conduct a systematic study of loops in C programs. We describe static analyses capable of efficiently identifying definite iteration in C code. One of the things computers can do more efficiently than humans is repetitive tasks.

A for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times. Syntax: The syntax of a for loop in C programming language is: for ( init; condition; increment ) {statement(s);} Here is the flow of control in a for loop: 1. The init step is executed first, and only once.

The syntax of for loop in c language is given below: 1. for (initialization;condition;incr/decr){ 2. //code to be executed 3.} do while loop in C The do while loop is a post tested loop. Using the do-while loop, we can repeat the execution of several parts of the statements.
