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(...
C while 循环 C 循环 只要给定的条件为真,C 语言中的 while 循环语句会重复执行一个目标语句。 语法 C 语言中 while 循环的语法: while(condition) { statement(s); } 在这里,statement(s) 可以是一个单独的语句,也可以是几个语句组成的代码块。condition 可
This example is functionally equivalent to the first while loop example above and will result in an infinite loop. While vs Do While Let's consider the previous while loop boolean trigger example. If I had initialized the value of keepGoing as false, the code in the while loop would have ...
Flowchart of C++ while loop Example 1: Display Numbers from 1 to 5 // C++ Program to print numbers from 1 to 5 #include <iostream> using namespace std; int main() { int i = 1; // while loop from 1 to 5 while (i <= 5) { cout << i << " "; ++i; } return 0; } ...

The while loop is particularly useful when the number of iterations is not known or cannot be determined in advance. The general syntax of the while loop is as follows: 1 2 while (expr) statement ; where expr is the loop control or test expression that may be any valid C expression such...
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;} ...
Example: For loop in C Compiler // Program to print numbers from 1 to 10 #include <stdio.h> int main() { int i; for (i = 0; i < 10; i++) { printf("%d\n", i+1); } return 0; } Run Code >> The above code prints the numbers from 1 to 10 using a for loop in...
Note:For those who don’t know printf or need to know more about printf format specifiers, then first a look at ourprintf C language tutorial. Let’s look at the “for loop” from the example: We first start by setting the variable i to 0. This is where we start to count. Then ...
If loop contain only one statement then braces are optional; generally it is preferred to use braces from readability point of view. For example : for (j=0;j<5;j++) printf("j”); Loops can be nested too. There can be loop inside another loop. Given below is example for nested loop...
