While Loop Examples: Example 1: /* echo.c -- repeats input */#include <stdio.h>intmain(void){intch;/* * 1. getchar() function reads-in one character from the keyboard * at a time * 2. return type of getchar() is int * 3. getchar() returns integer value corresponding to cha...
Flow-chart of while loop in C In the while loop, evaluation of the controlling expression takes place before each execution of the loop body. How does the while loop work? Step 1.The while loop evaluates the controlling expression.
// infinite do...while loopintcount =1;do{// body of loop}while(count ==1); In the above programs, theconditionis alwaystrue. Hence, the loop body will run for infinite times. for vs while loops Aforloop is usually used when the number of iterations is known. For example, ...
Another example, with a constant value as condition, which is alwaystruehence the code will keep on executing. Jumping Out of Loops in C Sometimes, while executing a loop, it becomes necessary to skip a part of the loop or to leave the loop as soon as certain condition becomestrue. This...
C while Loop: Example 2 Print integers from 1 to 5 using the while loop. #include<stdio.h>intmain(){inti;//loop counter//method 1printf("Method 1...\n");i=1;while(i<=5){printf("%d",i);i++;}printf("\n");//method 2 (increment is in printf statement)printf("Method 2.....
Example-8: Using C-style while loop Create a bash file named while8.sh with the following code. Here, the while loop has been declared in a c-style format that will iterate 5 times by incrementing the counter value by 10. #!/bin/bash # Initialize the counter n=5 # Define the whil...
This program is a very simple example of a for loop. x is set to zero, while x is less than 10 it calls printf to display the value of the variable x, and it adds 1 to x until the condition is met. Keep in mind also that the variable is incremented after the code in the ...
The do...while loop is used to run a block of code multiple time until a specific condition is true. In this tutorial, we will learn about the do-while loop its use, syntax, example.
使用loop表达式时,停止循环的唯一方法是以程序员身份直接进行干预。 可添加特定代码来停止循环,也可输入 Ctrl+C 等键盘指令以停止程序执行。 停止loop表达式的最常见方法是使用break关键字设置断点: Rust loop{// Keep printing, printing, printing...println!("We loop forever!");// On the other hand, maybe...
In the example above, the while loop will run, as long i is smaller then twenty. In the while loop there is an if statement that states that if i equals ten the while loop must stop (break). With “continue;” it is possible to skip the rest of the commands in the current loop ...
