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...
whileLoopExample(); // 调用while循环示例函数 doWhileLoopExample(); // 调用do-while循环示例函数 return 0; // 程序结束，返回0表示正常退出 } // 使用for循环打印1到10的数字 void forLoopExample() { // for循环初始化变量i为1，循环条件是i小于等于10，每次循环后i增加1 for (int i = 1; i <...
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(...
Below is the flow chart of the do...while loop -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,...
do-while 循环已结束,流程已流出。 流程图while循环(用于控制流): 示例1:该程序将尝试打印“Hello World” 5 次。 C实现 // C program to illustrate while loop #include<stdio.h> intmain() { // initialization expression inti=1; // test expression ...
Example: #include<stdio.h> void main() { int i = 20; while( i <=20 ) { printf ("%d " , i ); i++; } } Output: 20 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...
do{ //code to be executed }while(test condition); The body of the loop executes before checking the condition. If the test condition is true, the loop body executes again. Again the test condition is evaluated. The process repeats until the test condition becomes false. Example: do...wh...
例子(Example) #include <stdio.h> int main () { /* local variable definition */ int a = 10; /* do loop execution */ do { printf("value of a: %d\n", a); a = a + 1; }while( a < 20 ); return 0; } 编译并执行上述代码时,会产生以下结果 - ...
Examples of infinite while loop Example 1: #include<stdio.h>intmain(){intvar=6;while(var>=5){printf("%d",var);var++;}return0;} Infinite loop:var will always have value >=5 so the loop would never end. Example 2: #include<stdio.h>intmain(){intvar=5;while(var<=10){printf("%d...
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 progr...
