C++ Lecture 13 In Urdu

For  Loop

    for loop use for counter ……
4 parts in for loop
(1) initialization

(2) condition

(3) increment and decrement

(4)body of loop

 Intialzation me ham varible ko value dity hai  // a=11 or h=7 or j=9 etc

Condition me u know k contion check karty hai  // a<=90 or h>=1 etc

++    --- 

{
statement;
}

syantx
 for(initialize;condtion;++/--)
{
statement;

}

#include<iostream.h>
#include<conio.h>
void main()
{
int a;
for(a=1;a<=5;a++)
cout<<a<< endl;
getch();
}


#include<iostream.h>
#include<conio.h>
void main()
{
int a= 1;
for(;a<=5;)
{
cout<<a<<endl;
a++;
}
getch();
}

ye dono programme same hai ye ap logo ko dikna ta k esa b ho sakta hai ok  chaloo ab es ko run kartyu hai kon run kary ga mujy to nahe ata

·        Acha es me ham ne int type ka a varible liya

·        Per for loop lagi k agr a less hai 5 se ya eqal hai to true hai q k a ke value 1 hai a me increment ho jai ge

·        Body me ajy ga 1 print ho jy ga line change ho jai ge q k endl lagi hai

·        a me increment ho ge 2 ho jay ga

·        loop me check kary ga to liss hai true ho ga

·        body me ajy ga 2 print ho jay ga

·        a me increment ho jay ga 3 ho jay ga

·        loop me jay condition check ho ge true hai q k a 3 hai ur 5 se less hai

·        3 print ho jay ga  a me ++ ho jay ga 4 ho jay ga

·        Loop me jay ga condtion check ho ge

·        Es traha ho jabn condition false ho jay ga to output aye

Table

#includde<iostream.h>
#include<conio.h>

Void main()
{
int tab,c,r;
cin>>tab;
for(c=1;c<=10;c++)
{
r=tab*c;
cout<<tab<<”*”<<c<<”=”<<r<<endl;
}
getch();
}

Ap sab es ka run approch comment me  likooo jes tarha me likta hun ok jesa while me and do-while kia ta same wesa he hai par us se na dikoo ok ur sab comment me likoooo tek hai

Note:: es k bad ek ur simple for loop ke practice ho ge than assignement and quiz ho ga ur bht zada tof ho ga ur per us k bad nested loops start hun gy
