c++ Lecture 10 in Urdu

                                                   

                                                   Loop In C++                        

 (2)do-while loop                                    

 (3)for loop

  (4)foreach loop   

Es me ham serf 3 loop karny gy while , do-while and for loop aj ham while loop karny gy ok lest start

While
      while me pehly condtion check ho ge than body chali ge

Syntx 
    while(condition)
{

Statement;
}           farz kary k hamry pass input k lay data zada hai to ham us mk lay kia per input karty rahain gy means k har waqat cin karna ho ga  esa ho ho sakta hai par es se hamra bht time waste ho ga to time space k lay ham loop use karnain gy  loop 4 type k hai

  (1)while loop

     #include<iostream.h>
    #include<iostream.h>
void main()
{
int a;
a=1;
while(a<=5)
{
cout<<”c++”;
a++;
}

Cout<<”ali”;
getch();
}

ok es programm me 5 times c++ aye ga than ali kesy diky
ham ne itn type ka varible liye jes ko hyam ne a ka nam assign kia per a ko 1 se initialize kia per condition lagi per cout kiaa per increament kia oer body se bahr a k cout kia acha ab dikty hai k ye while ke body kesy chali ge
ham ne condition lagi k a less ya equal ho 5 k to
a chota hai 5 se q k a 1 hai abi to true hai body me ajy ga ek bar output aye ge c++ per nect statement chali ge to a me increment ho ge a ke value 2 ho jai ge to oper per condition ko chala jay ga check kary ga ur check kary ga tro 2 chota hai 5 se condition true hai body me ajy ga ek bar per result aye ga c++ than a me increment ho ge abi condition true hai body se bahar nahe jay ga per oper jaa k condition check ho ge ab a ke value 3 hai to check kary ga to 3 , 5 se chota hai condtion true hai per ek ur oupt aye ge c++ then per a me incremewnt ho ge per a ke value 4 ho jai ge per check ho ga condition true ho ge per output aye ge per a me increment ho ge per 5 ho jai ge per condition checdk ho ge to 5 to 5 k equal hai ur ham ne condition lagi hai k a<=5 to true hai per chali ge a me increment ho ge a ke vaule 6 ho jai ge per check ho ge to false ho jai ur body se bahar jay ga ur ali wala statement chali ge per

I hope k samj aye ho ge
Note c++ me statmenet one bye one chali ge means k pehly jo satement ho ge pehly wo chali ge per us k bad jo ge wo chalie ge etc etc
