In programming, loops are used to repeat a block of code. In this tutorial, you will learn to create for loop in C programming with the help of examples.
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...
Real-Life ExamplesTo demonstrate a practical example of the for loop, let's create a program that counts to 100 by tens:Example for (i = 0; i <= 100; i += 10) { printf("%d\n", i);} Try it Yourself » In this example, we create a program that only print even numbers ...
Let’s take a look at the example: First you must always initialize the counter before the while loop starts ( counter = 1). Then the while loop will run if the variable counter is smaller then the variable “howmuch”. If the input is ten, then 1 through 10 will be printed on the...
Now that we have a clear understanding of the syntax and functionality of the for loop in C++, let's look at a few code examples. Example 1: To Find The Factorial Of A Number Using For Loop In C++ In this example, we’ll use a C++ for loop to calculate the factorial of a given...
In the above examples, we have declared a variable in theforloop to store each element of the collection in each iteration. intnum[3] = {1,2,3};// copy elements of num to varfor(intvar : num) {// code} However, it's better to write theranged based for looplike this: ...
For loop Examples Example - 1: The following program calculate the sum of 1+2+3+...+50. The sum is stated in sum = sum + x, where i takes values from 1 to 50. #include<stdio.h>main(){intsum;intx;sum=0;for(x=1;x<=50;++x)// x take values in {1,2,3,...,50}{sum...
Syntax and Examples of For Loop in C Programming The essential syntax of a for loop in C is: for ( ; ; ) This for loop lacks an evaluation expression. If nothing is evaluated as true or false, there can be no exit to this loop. If this program ran, it would begin an infinite ...
C For Loop Purpose, Flowchart, and ExampleSHARE In this C programming class, we’ll cover the C for loop statement, its purpose, syntax, flowchart, and examples. Please note that the loops are the main constructs to implement iterative programming in C....
更方便的 for loop 可以帮到你 ! 简化版 for loop: #define easyFor(var, start, end) for(int var = start; var <= end; var++) 试试计算 1 至 100 的总和: int sum = 0; easyFor(i, 1, 100){ // for(int i = 1; i <= 100; i++) sum += i; } printf("%d", sum); 天啊...
