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 ...
C For Loop Examples ❮ Previous Next ❯ 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 » ...
Example 3: Declare Collection inside the Loop #include<iostream>usingnamespacestd;intmain(){// define the collection in the loop itselffor(intn : {1,2,3,4,5}) {cout<< n <<" "; }return0; } Run Code Output 1 2 3 4 5 Here, we have declared the collection within the loop itsel...
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
Nested For Loop in C Nesting of loop is also possible. Lets take an example to understand this: #include<stdio.h>intmain(){for(inti=0;i<2;i++){for(intj=0;j<4;j++){printf("%d, %d\n",i,j);}}return0;} Output: 0,00,10,20,31,01,11,21,3 ...
Loops can be nested too. There can be loop inside another loop. Given below is example for nested loop to display right angle triangle of ‘@’ symbol. for (i=0; i < 5; i++) { for (j=0;j<=i;j++) { printf("@”);
Example 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 aga...
C while Loop: Example 1Input two integers and find their average using while loop.#include <stdio.h> int main() { int a, b, avg, count ; count =1; while( count<=3 ) { printf("Enter values of a and b: "); scanf("%d %d",&a,&b); avg=(a+b)/2; printf("Average = %d...
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 a number: "; cin >> n; for (int i = 1; i <= n; i++) {...
Example: For loop in C Compiler // Program to print numbers from 1 to 10 #include <stdio.h> int main() { int i; for (i = 0; i < 10; i++) { printf("%d\n", i+1); } return 0; } Run Code >> The above code prints the numbers from 1 to 10 using a for loop in...
