C++ Lecture 11 In Urdu

                   While loop practice

#include<iostream>

#include<conio.h>

void main()

{

     int a;

     cout<<"Enter the Number :";

     cin>>a;

     int c=1;

      while (c <= a)

     {

         cout<<"Execute While "<<c<<" time"<<endl;

         c++;

     }

   Cout<<”Mt Ali okz”;

     getch();

 }

·        Pehly ham ne int type ka variable liya jes ko ham ne a ka name assign kia

·        Per user se us ke value lain gy jo k user int type ka dy ga

·        Per int type ka c liya ur 1 se initilize kia c counter k lay kam kary ga

·        Per while ke conndition lagi

·        Condition check ho ge farz kary k user ne a ko 3 value de hai

·        C ke value 1 hai to condition true hai q k 1 less hai 3 se

·        Body me aye ga cout ke statement execute ho ge

·        Execute while 1 time aye ga line change ho jai ge

·        C me increment ho ge 2 ho jai ge

·        Oper jai ge condition check ho ge

·        2<=3 to ture hai

·        Body me aye ge

·        Cout ke satement execute ho ge

·        Execute while 2 time aye ga line changew ho jay ga

·        C me increment ho jai ge 3 ho jay ga

·        Oper jay ga condition check ho ge

·        3<=3 true hai q k equl to hai na

·        Body me aye ga cout ke ststement execute ho ge

·        Execute while 3 time line change ho jai ge

·        C me increment ho ga 4 ho jay ga

·        Condtion check ho ge to false ho jay ga q k 4 greater hai 3 se

·        Body se bahar ajy ga .

·        Next staement chali Mt Ali okz wali ou output ye aye ge

Execute while 1 time

Execute while 2 time

Execute while 3 time

Mt Ali okz

#include<iostrem.h>

#include<conio.h>

void main()

{

int tab,res,c;

cin>>tab;

c=1;

while(c<=5)

{

res=tab*c;

cout<<tab<<”*”<<c<<”=”<<res<<endl;

c++;

}

cout<<”multiplication table”;

getch();

}

·        Es me ham multiplictaion ka table bany gy

·        3 varibale lle hai int type ke tab ,res, c

·        Tab use for table jes ka ham table bany gy farz kary k user ne 5 ka bana hai to user ne 5 input dia

·        Res use for result.

·        C use for count e.g 1,2,3,4 etc ur 1 se initialize kai

·        Condition chali ge while ke c less hai ya equl 5 k to less hai q k c 1 hai

·        Body me aye ga  res=tab*c ho ga res=5*1

·        Next staement chali ge 5*1=5 ho ga line change ho jai ge

·        C me increment ho ge c ke value 2 ho jai ge oper jay ga condtion check ho ge

·        ]condtion true hai q k 2 less hai 5 se

·        Body me aye ga res=5*2

·        Next staement 5*2=10 ho line change ho ge

·        C me increment ho ge 3 ho jay ga

·        Es tarhqa ho ga per c ke value 5 ho ge to chali ge q k true hai q k ham ne condition lagi hai less ho ya equl to equal hai

·        Per increment ho ge to c ke value 6 ho jai ge condtion false ho jai ge ur while k body se bahr aye

·        Next satement chali ge

·        multiplication table

 output

    5*1=5
    5*2=10
    5*3=15
    5*4=20
    5*5=25
    multiplication table

To aj k lay itna kafi ta agy InshAllah es k bad do-while start karain gy
