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.
C/C++ 中的循环在我们需要重复执行一个语句块时派上用场。 For 循环是一种重复控制结构,它允许我们编写一个执行特定次数的循环。循环使我们能够在一行中一起执行 n 个步骤。 语法: for(initialization expr;test expr;update expr) { // body of the loop // statements we want to execute } For 循环的...
Step 2:In the second step the condition is checked, where the counter variable is tested for the given condition, if the condition returns true then the C statements inside the body of for loop gets executed, if the condition returns false then the for loop gets terminated and the control ...
Case2 (Always FALSE condition): Variables ‘i’ is initialized before ‘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 and loop statement is NOT executed.Here, it is noted ...
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...
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 ...
for(inti =0; i <5; i++) { cout << i <<"\n"; } Try it Yourself » Example explained Statement 1 sets a variable before the loop starts:int i = 0 Statement 2 defines the condition for the loop to run:i < 5. If the condition is true, the loop will start over again, if...
discussed the three main loops in C: for, while, and do-while. Each loop type serves specific iteration needs, making code efficient and concise. Understanding these loops is key to writing better C programs. Master these loops with ouradvanced C programming courseand elevate your programming ...
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...
