while loop in CIt repeatedly carries out a series of instructions till a condition is true. It is an entry-controlled loop. The while loop in C is used when we don’t know the number of iterations.while loop Flowchart Syntax while(test condition){ //code to be executed } If the ...
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...
Example 1: while loop // Print numbers from 1 to 5 #include <stdio.h> int main() { int i = 1; while (i <= 5) { printf("%d\n", i); ++i; } return 0; } Run Code Output 1 2 3 4 5 Here, we have initialized i to 1. When i = 1, the test expression i <= 5 ...
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...
A do...while loop is an example of the exit-control loop because in this the code is executed before the evaluation of the specified condition. It runs till the Boolean condition stands to be true, once it evaluates to be false the loop gets terminated at that point of time....
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); ...
C do...while Loop: Example 1Input two integers and find their average using do while loop.#include <stdio.h> int main() { int a, b, avg, count ; count =1; do { printf("Enter values of a and b: "); scanf("%d %d",&a,&b); avg=(a+b)/2; printf("Average = %d" , ...
不像for和while循环,它们是在循环头部测试循环条件。在 C 语言中,do...while循环是在循环的尾部检查它的条件。 do...while循环与 while 循环类似,但是 do...while 循环会确保至少执行一次循环。 语法 C 语言中do...while循环的语法: do{statement(s);}while(condition); ...
// The loop goes while x < 10, and x increases by one every loop for(intx = 0; x < 10; x++ ) { // Keep in mind that the loop condition checks // the conditional statement before it loops again. // consequently, when x equals 10 the loop breaks. ...
Output of while loop: Output of do-while loop: b: 11 Note that thewhileloop doesn't take any iterations, but thedo-whileexecutes its body once. This is because the looping condition is verified at the top of the loop block in case ofwhile, and since the condition is false, the prog...
