FINAL EXAM STRUCTURE

Output (15%)

Debugging (15%)

Writing Simple Statements (20%)

Writing Simple Program x 2 (20%)

Writing Program with Functions x 2 (30%)





Looking For Output…. int beta =6;

switch(beta)

{ case 1:case 3:

beta = beta + 2;

case 4:

beta = 2 * beta;break;

case 6:

beta++;

case 7:

beta = 2*beta;

case 8:beta = beta +5;

break;

default:

beta--;}

cout<<beta;

Function (2 Types)

return type

string getName(string N, string lN){ return fN + “ “ + lN; }

void type

void printName(string fN, string lN){ cout<< fN << “ “ << lN; }



Writing Simple StatementsAssume that all variables are declared. Write C++statements to accomplish each of the following:

Assign the sum of the pre-decremented value of aand b to c.

c = --a + b;

Print out a message “You are clever” if mark isbetween 80 and 100 and mark is not 0

if( (mark>=80 && mark<=100) && mark!=0)

{ cout<<“You are clever”; }



Writing Simple Statements Sum the even integers between 1 and 99 using a for

statement and assign the result to sum.

int sum=0;

for(int i=1;i<=99;i++)

{ if (i%2==0)

sum+=i; // sum=sum+i

}

Set the value of the fifth element of the array alpha to themultiplication result of the first and third elements.

alpha[4] = alpha[0] * alpha[2];



Writing Simple Statements Compute the sum and average of all the five elements in the array alpha

and output the sum, average and value of each element.

double average=0.0;

int sum = 0;for (int i = 0; i<5;i++)

{

sum=sum+ alpha[i];

}

average = sum/5;

cout<<“Sum is”<<sum<<endl;

cout<<“Average is”<<average<<endl;

for (int i=0; i<5; i++)

cout<<alpha[i ];



Writing simple programWrite a C++ program that display table of conversion

between feets and meters begins from 0 feet to 50

feet with every 5 feet increment using for loop. Theconversion formula is: meter = 0.305 * foot

cout<< setw(10)<<"Feet" << setw(10)<<"Meter"<<endl;

for(int ft=0; ft<=50; ft+=5)cout<<setw(10)<<ft<<setw(10)<<0.305*ft<<endl;





const int N = 3;

/* The function for adding two matrices */

void addMatrix(const double a[][N], const double b[][N], doublec[][N])

/* The function to print result of addition*/

void printResult(double m1[][N], double m2[][N], double m3[][N],char op)



Each element cij is aij + bij. Hereis the sample run:
