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 ...
Example 2: for loop // Program to calculate the sum of first n natural numbers// Positive integers 1,2,3...n are known as natural numbers#include<stdio.h>intmain(){intnum, count, sum =0;printf("Enter a positive integer: ");scanf("%d", &num);// for loop terminates when count ...
In the above example we have a for loop inside another for loop, this is called nesting of loops. One of the example where we use nested for loop isTwo dimensional array. Multiple initialization inside for Loop in C We can have multiple initialization in the for loop as shown below. for...
These are statements such as break, return, or goto. To demonstrate a more functional for loop in C programming language, take the example of a program that counts down from ten to start a game of hide and seek. The for loop will take three expressions:...
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
The “For” loop vs. “Switch” case in C The for() loop iterates through set code blocks. The switch() case, on the other hand, iterates through discrete code blocks. Consider the following example: int i; i = 4; switch(i) { ...
1) for loop as an infinite loop to hold execution When, we need to hold execution of program (or hang the program), we can use thefor loop as an infinite loop. for(;1;); Consider the program: #include<stdio.h>#include<stdlib.h>intmain(){printf("start...\n");fflush(stdout);fo...
To 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 between 0 and 10 ...
Here is a basic C program covering usage of ‘do-while’ loop in several cases: #include <stdio.h> int main () { int i = 0; int loop_count = 5; printf("Case1:\n"); do { printf("%d\n",i); i++; } while (i<loop_count); ...
Example: #include<stdio.h> void main() { int i = 20; while( i <=20 ) { printf ("%d " , i ); i++; } } Output: 20 2. do – while loop in C It also executes the code until the condition is false. In this at least once, code is executed whether the condition is true...
