The do/while loop is a variant of the while loop. This loop will execute the code block once, before checking if the condition is true, then it will repeat the loop as long as the condition is true.Syntax do { // code block to be executed } while (condition); ...
In this tutorial, we will learn the use of while and do...while loops in C++ programming with the help of some examples. Loops are used to repeat a block of code
C while Loop: Example 1 Input two integers and find their average using while loop. #include<stdio.h>intmain(){inta,b,avg,count;count=1;while(count<=3){printf("Enter values of a and b:");scanf("%d%d",&a,&b);avg=(a+b)/2;printf("Average =%d",avg);}return0;} ...
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...
Do 在编程中一般指代“做”或“执行”,1、半独立执行块,在某些编程语言中,如 C 或 Java,do 通常与 while 关键词结合使用,构成 do-while 循环,它保证了循环体至少执行一次,即使循环条件初始值为假。在 do-while 循环中,循环体里的代码首先执行,然后才检查循环条件。
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...
Value < 33 Then Range("C" & i).Offset(0, 1).Value = "Fail" Else Range("C" & i).Offset(0, 1).Value = "Pass" End If i = i + 1 Loop End Sub Visual Basic Copy Close the Visual Basic window. Go to the Developer tab and select Macros. Select Do_While_Loop_Offset in ...
Loops are used in programming to execute a block of code repeatedly until a specified condition is met. In this tutorial, you will learn to create while and do...while loop in C programming with the help of examples.
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 // ...
Conclusion In this tutorial, we have learned aboutfor,whileanddo-whileloops in C and why they are important, along with seeing them in action with multiple code examples. We also learnt aboutbreakandcontinuestatements. ← Prev Next →
