4.Change the algebra expression to anthmetic expression

a)     Y = m – 4ax

    7a

            Answer :   Y = (m - 4 ax) / 7a

b)    Y  =    6ab___

      4sd – 2xy

Answer :  Y = 6 bc / (4 sd – 2xy)

c)     Y = 2 + (AB + ( )   + 5 xyz

                               3d

             Answer : Y = (( 2 + AB + c ) / 3d ) + 5 xyz

d)    Y = 2kb = 3jb

       2k1

Answer : Y = (2kb / 2 ki ) – 3 jb

e)     Y = xy + x² – 2ab

Answer : Y= xy + x * x – 2 ab

Solve the statement below to find in value. Show the working :-

a)     M=5

       M * = (3 + 4) * 2

Answer :-

    M =   5 * ( 3 + 4 ) * 2

    M =   (5 * 7 )* 2

    M =    35 * 2

    M =    70

                        1 (TRUE)

b)    M=2

M * = ((3 *4 ) / 2 ) = 9

Answer :-

M =  2 * (12/ 2 ) =9

M =  ( 2* 6 ) = 9

M =   12 = 9

      0 (FALSE)

6. Find the output for the following segment:-
a) float var 1 = 25.12, var 2 = 15.0;
if (var 1<= var 2) cout<<"var 1 less or same as var 2"; else cout<<"var 1 bigger than var 2"; 
b) int n = 20; n/= 5;

Answer :-

Output :

Cout<<Var1 bigger than Var 2 “ ;

<!--[if !supportLists]-->b)    <!--[endif]-->In n = 20 ;

    n/ = 5 ;

             

            Answer :-

            Output  :

            Cout<<20 / 5 = 4 “ ;

7.  Convert the while statement below for for statement :-

Int j = 10 ;

While ( j > 10)

{

                Cout << “             “ << j ;

                J______ ;

}

Answer :-

#incude<iostream.h>

Main  ()

{

//declare variable

Int x  ;

X = 1 ;

While (x < = 10 )

{

Cout<<”number “<<x*1 ;

X ++ ;

}

return 0;

}

Output : 

Number 1 --------- 1

              2 --------- 2

              3 --------- 3

              4 --------- 4

              5 --------- 5

              6 --------- 6

              7 --------- 7

              8 --------- 8

              9 --------- 9

             10 --------- 10

8.Write a program the reads 4 prices using while loop and calculate the sum of things. A program must use function while for calculate the average of the prices.

#include<iostream.h>

main ()

{

                int k;

                float p,total,averge;

                k=1;

                while (k<=4)

                {

                                cout<<"Enter price "<<k<<"= ;

                                cin>>p;

                                k++;

                                total=total+p;

                }

                  Average=total/4;

                  cout<<"Your total is "<<total<<"and average is "average;

                  return 0;

}
