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 number step by step. Code Example: #include <iostream> using namespace std; int main() { int n, factorial = 1; cout << "Enter ...
In this example, we declared and initialized an int array named numArray. Here, we used the ranged for loop to print out the elements of numArray. first iteration - n takes the value of the first member of the array, which is 1 second iteration - n takes the value of 2 and is the...
In the above example, we have two variables num and sum. The sum variable is assigned with 0 and the num variable is assigned with the value provided by the user. Note that we have used a for loop. for(int i = 1; i <= num; ++i) Here, int i = 1: initializes the i variable...
A loop is used for executing a block of statements repeatedly until a particular condition is satisfied. For example, when you are displaying number from 1 to 100 you may want set the value of a variable to 1 and display it 100 times, increasing its valu
for 循环允许您编写一个执行特定次数的循环的重复控制结构。语法C++ 中 for 循环的语法:for ( init; condition; increment ) { statement(s); } 下面是 for 循环的控制流:init 会首先被执行,且只会执行一次。这一步允许您声明并初始化任何循环控制变量。您也可以不在这里写任何语句,只要有一个分号出现即可。
The condition is now evaluated again. If it is true, the loop executes and the process repeats itself (body of loop, then increment step, and then again condition). After the condition becomes false, the for loop terminates.Flow DiagramExampleOpen...
Statement 3 increases a value (i++) each time the code block in the loop has been executed. Another Example This example will only print even values between 0 and 10: Example for(inti =0; i <=10; i = i +2) { cout << i <<"\n"; ...
