The program is an example ofinfinite while loop. Since the value of the variable var is same (there is no ++ or – operator used on this variable, inside the body of loop) the condition var<=2 will be true fore
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...
Awhileloop statement in C programming language repeatedly executes a target statement as long as a given condition is true. Syntax while(expression) statement If theexpressionis true, thestatementwill be executed and then theexpressionwill be re-evaluated to determine whether or not to execute the...
In this example, the program asks the user to enter numbers continuously until they enter 0. It keeps calculating the sum of the entered numbers. Once the user enters 0, the loop terminates, and the program prints the total sum. The loop is executed at least once because the condition is...
In simple words, in an entry-controlled loop, the condition is checked at the beginning of each iteration.If the condition evaluates to true, the loop body is executed. If the condition is false from the start, the loop body is skipped entirely, and the program continues with the code ...
C中的While-loop重新打印前面的语句 在C语言中,while循环是一种迭代结构,用于重复执行一段代码块,直到指定的条件不再满足为止。在while循环中,如果条件为真,则执行循环体中的语句,然后再次检查条件是否为真,如果为真则继续执行循环体,直到条件为假时循环结束。
If the condition becomesfalsein the beginning itself, the program control does not even enter the loop once. The loop executes untilibecomes 10. Output 12345678910 do...while loop in C It is an exit-controlled loop. It prints the output at least once before checking the condition. Afterwards...
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
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(...
Write a C program that uses a while loop to calculate and print the sum of the even integersfrom 2 to 30. 相关知识点: 试题来源: 解析 #include int main() { int sum = 0; int i = 2; while (i <= 30) { sum += i; i += 2; } printf("Sum of even integers from 2 to 30 ...
