C++ lecture 3 In Urdu

Keyword…
     Esy word jes ka c++ me ek maqasd hota hai u rap es ko kesi variable  par use nahe kar sakty….
ur keyword ka hamesha color changer ho ga c++ me es me bht zada keyword hai kuch me likta u rap net se dik ly

                   Auto  , double, ,if, else , int , float , char , for , while , do , short , void , goto , case, switch

  Es tarha k bht hun gay ap google par dik ly dikoo me har time kehta hun google py dik loo woe s lay k mera kam serf samjna hota hai baqi ka map logo ne karna ho ga ok
…………………………………………………………………………………………………………………………………………
Variable ….
        variable asl me khud kuch nahe hoty par ham es me koi value dity hai variable ka serf itna kam hai k memry me jaga ka nam ban jata hai ur waha py ham kuch enter karta hai understand ur hamesha variable ham alphabet lain gy

                 Ex…     a,b,c,g,h,j,l,I,p etc es tarha…….

                 Ek hota hai variable intionlization… jes me ap variable ko declare karty waqt value provide karty ho us ko variable intionlization kehty hai  ex… a=3  ur ye value ham kabi change nahe kar sakty hai ye constant ho ge hameshaa  ////////////////////////////////////////////////////////////////////////////////////////////////

          DataTypes…..
     data type ham use karty hai k complir ko pata chaly k kes type ke value hai es me dattype ye int means k intger   float    floating value mens k . wali char ,, double use karty hai jo k bari value ho agr ap ne double lagya to per float ke jetni bari value ho dy saktyu ho
pic.. dik lay
 

             Es k bad programming ke practice karty hai

Aj me ek simple sa program banoo ga jes me ham 5 paper k marks ko add karain gay 

                         #include<iostream.h>    //use for input output
         #include<conio.h>
         void main()
         {
            clrscr();
float  a,b,c,d,e,marks;
           cin>>a>>b>>c>>d>>e;
            marks=a+b+c+d+e;
           cout marks;
           getch();
            }

                Es me jo a,b,c,d,e liya hai ye paper k lay variable liye hai jo k float me liya shayd hamry marks point me ho..
es k bad ham user se marks ka input me lain gy
per wo marks me add hung y ur res;t show hoo ga
es tarha ap log khud se * ,-,/ ka program ban lay to behtar ho ga agr ap log serf ye read karain gay to kuch samj nahe aye ga pl zap log khud practice kia karyy warna ap loog nahe seek pain gy q k C++ practice se seeki jate hai plz members me itne takleef karta hun ap log b sat dia kary

                  And ha me urdu me es lay pharta hun taky ap logo ko achi samj ajy agr per b samj nahe ate to mujy ek ur language ate hai jes se ap logo koo samj aye ge wo hai PASHTO hahahah just kiiding
