while loop Flowchart Syntax while(test condition){ //code to be executed } If the test condition inside the () becomes true, the body of the loop executes else loop terminates without execution. The process repeats until the test condition becomes false. Example: while loop in C // ...
Example 2: do...while loop // Program to add numbers until the user enters zero #include <stdio.h> int main() { double number, sum = 0; // the body of the loop is executed at least once do { printf("Enter a number: "); scanf("%lf", &number); sum += number; } while(...
Case2 (Always FALSE condition): Variables ‘i’ is initialized before ‘do-while’ loop to ‘20’; iteration is increment of counter variable ‘i’; condition is FALSE always as ‘0’ is provided that causes NOT to execute loop statements, but it is noted here in output that loop stateme...
Example int i = 0;do { cout << i << "\n"; i++;}while (i < 5); Try it Yourself » Do not forget to increase the variable used in the condition, otherwise the loop will never end!Exercise? What is a key difference between a do/while loop and a while loop? A do/while...
C while Loop: Example 2 Print integers from 1 to 5 using the while loop. #include<stdio.h>intmain(){inti;//loop counter//method 1printf("Method 1...\n");i=1;while(i<=5){printf("%d",i);i++;}printf("\n");//method 2 (increment is in printf statement)printf("Method 2.....
The example forwhile Loop in Ccan re-written as follows: #include<stdio.h> #include<conio.h> void main() { int i=0; clrscr(); do{ i=i+1; printf("%d This will be repeated 5 times\n", i); }while(i!=5); printf("End of the program"); getch(); } ...
1. Awk While Loop Example: Create a string of a specific length $awk 'BEGIN { while (count++<50) string=string "x"; print string }' xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx The above example uses the ‘BEGIN { }’ special block that gets executed before anything else in an Aw...
For example, // infinite while loop while(true) { // body of the loop } Here is an example of an infinite do...while loop. // infinite do...while loop int count = 1; do { // body of loop } while(count == 1); In the above programs, the condition is always true. Hence,...
} while ( x != 0 ); cin.get(); }Keep in mind that you must include a trailing semi-colon after the while in the above example. A common error is to forget that a do..while loop must be terminated with a semicolon (the other loops should not be terminated with a semicolon, ad...
} while(1); return 0; } Another example, with a constant value as condition, which is alwaystruehence the code will keep on executing. Jumping Out of Loops in C Sometimes, while executing a loop, it becomes necessary to skip a part of the loop or to leave the loop as soon as certa...
