c++ Lecture 14 In Urdu

For loop practice

#include <iostream>
#include<conio.d>
void main()
{
    int i, n, f= 1;
    cout<<"Enter a number: ";
    cin>>n;
    for (i = 1; i <= n; i++)
    {
     f *= i;   // f = f * I
    }
    cout<< "Factorial of "<<n<<" = "<<f;
    getch();
}

·        Es me hm ne 3 varible liye int type k.

·        I for looping n for input from user and f fort factorial.

·        Ur f ko 1 se initialize kia

·         Per usr se input le jo n me save ho ge

·         Es kl bad loop start ho ge I o 1 se inityalize kia

·         Es k bad condition check ho ge I less hai ya erqual hai n se farz kary user ne 5 input liya hai

·         Ha chota hai es k bad pehly 1 add ho jay ga n k sat 2 ho jay ga

·         Body me ga execute hop ga

·         Per loop py jay ga condition check ho ge true hai 2 bara hai  per body me aye ga body execute ho ge

·         Es tarha hota rahy ga jab 5 se bara ho jai I to flase ho k bahar aye ga body se

·         Ur output aye ge

Enter a positive integer: 5

Factorial of 5 = 120

#include<iostream>
#include<conio.h>
void main()
{
     int a;
     cout<<"Enter the Number :";
    cin>>a;
    for (int c = 1; c<= a; c++)

     {
    cout<<"Execute "<<c<<" time"<<endl;
   }
 getch();
}

 Write run approch

Enter the Number :5

Execute 1 time

Execute 2 time

Execute 3 time

Execute 4 time

Execute 5 time
