1. Draw the Flowchart and write the program to calculate the area of 15 rooms. The length is 55.2meters, and breadth is 26.34meters.

Flowchart

Program #include using namespace std; int main() { double length,breadth,area; length=55.2; breadth=26.34; area=15.0*55.2*26.34; cout<<”Area of 15 Rectangle Room is”<

2. You have been given a job as a programmer on a Software company. In order to accomplish some calculations, you need to know how many bytes the following data types use: char, int, float and double. You do not have manuals, so you can’t look this information up. Write a C++ program that will determine the amount of memory used by these types and display the information on the screen.

#include using namespace std; int main() { cout<<”The size of int data type is”<

Algorithm Step 1: Start Step 2: Set petrol=60,distance=350 Step 3: Calcultae MPL=distance/petrol Step 4: Print MPL Step 5: Stop

Program #include using namespace std; int main() { float distance=350.0,petrol=60.0,MPL; MPL=distance/petrol; cout<<”The Miles Per Litter of Car is”<

4.Write the algorithm and C++ program to convert from inches to meters Hint: 1 inch = 0.0254 meters

Algorithm Start Step 1: Read inches Step 2: meters=0.0254*inches Step 3: Display the meters Stop

Program #include using namespace std; int main() { double inches,meters; cout<<”Enter the values in inches”<>inches; meters=0.0254*inches; cout<<”Value in meters is”<

Algorithm Step 1: Start Step 2: Set MPLtown=21.5, MPLhway=26.8, petrol=20 Step 3: Calculate distancet=petrol*MPLtown Step 4: Calculate distanceh=petrol*MPLhway Step 5: Print the distancet Step 6: Print the distanceh Step 7: Stop

Program #include using namespace std; int main() { float MPLtown=21.5f,MPLhway=26.8f,petrol=20.0f,distancet,distanceh; distancet=petrol*MPLtown; distanceh=petrol*MPLhway; cout<<"The Distance in Town is"<

6..Modify the following program so it prints two blank lines between each lines of text. #include using namespace std; int main() { cout<<"Two mandolins like creatures in the"; cout<<"dark"; cout<<"Creating the agony of ecstasy."; cout<<" - George Barker"; return(0); }

Answer #include using namespace std; int main() { cout<<"Two mandolins like creatures in the\n\n\n"; cout<<"dark\n\n\n"; cout<<"Creating the agony of ecstasy.\n\n\n"; cout<<" - George Barker"; return(0); } \

8. Draw the flowchart and write the C++ program to calculate the pay of employee (for one day) based on the hour basis. Hint: pay= Amount Per Hour*Number of Hours Worked

Flowchart

Program #include using namespace std; int main() { float hours,amount,pay; cout<<”Enter the value for hours”<>hours; cout<<”Enter the value for amount”<>amount; pay=amount*hours; cout<<”The pay of employee is”<
