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 // ...
Now, just as we saw in the for loop, there can be various ways in which we can achieve this result.C while Loop: Example 2Print integers from 1 to 5 using the while loop.#include <stdio.h> int main() { int i; //loop counter //method 1 printf("Method 1...\n"); i=1; ...
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(...
2. do – while loop in C It also executes the code until the condition is false. In this at least once, code is executed whether the condition is true or false but this is not the case with while. While loop is executed only when the condition is true. Syntax: do{ //code }whil...
Here is a basic C program covering usage of ‘do-while’ loop in several cases: #include <stdio.h> int main () { int i = 0; int loop_count = 5; printf("Case1:\n"); do { printf("%d\n",i); i++; } while (i<loop_count); ...
Example inti =0; do{ cout << i <<"\n"; i++; } while(i <5); Try it Yourself » Do not forget to increase the variable used in the condition (i++), otherwise the loop will never end! Condition is False from the Start ...
C programming Looping (while, do while, for) programs – C solved programs. This section provides you solved c programs of C looping using for, while and do while.
intmain() { intx; x = 0; do{ // "Hello, world!" is printed at least one time // even though the condition is false cout<<"Hello, world!\n"; }while( x != 0 ); cin.get(); } Previous: If Statements Next: Functions
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,...
