Task 2.1: Declare and initialize an array of size taken from user as input, display array values on screen And find sum of array elements and finally display the summation result. #include using namespace std; int main() { int n,sum=0; int array[n]; cout<<"Enter the Array size: "; cin>>n;
for(int i=0; i<n; i++){ cout<<"Enter element"<<i+1<<" : "; cin>>array[i]; }
cout<<"\n{ "; for(int i=0; i<n; i++){ cout<<array[i]<<","; } cout<<" }\n"; for(int i=0; i<n; i++) { sum=sum+array[i]; } cout<<endl; cout<<"The sum of all element : "<<sum<<endl; }
Task 2.2: Declare an array of size 8. Receive all the elements from the user as input using for- loop. Display the entered elements from user as input in reverse order. #include using namespace std; int main() { system("color f0"); int array[8];
cout<<"Enter 8 Element of array"<<endl; for(int i=0; i<8; i++) { cin>>array[i]; } cout<<"Array elemnt in Reverse Order: "; for(int i=0; i<8; i++) {cout<<array[i]<<",";} }
Task 2.3: Use an int pointer and an int variable and displays the variables address.
#include using namespace std; int main() { system("color f0"); int variable; int *ptr; cout<<"Address of Variable: "<<&variable<<endl; cout<<"Address of Pointer : "<<&ptr<<endl; }
Task 2.6: Create a class named “Car” with attributes xPosition, yPosition, speed. The class should have methods such as “accelerate”, “decelerate” to increment and decrement the speed of the car while for change in xPosition & yPosition, there should be methods such as turn Left, turnRight. A n extra method“currState” should display all the data members of the object. #include using namespace std; class Car { private: float xPosition, yPosition, speed; public: Car(float x,float y,float sp) { xPosition=x; yPosition=y; speed=sp; } float accelarate() { ++speed; } float deaccelarate() { --speed; } float moveX(float a) {xPosition+=a;} float turnLeft() {moveX(-1.0);} float turnRight() {moveX(1.0); } void currState() { std::cout << "I am in xPosition " << xPosition << " and yPosition " << yPosition << " with velocity " << speed << std::endl; } }; int main() { Car c(1.7,3.3,100.3); c.accelarate(); c.deaccelarate(); c.moveX(1.0); c.turnLeft(); c.turnRight(); c.currState(); return 0; }
Task 2.7: Create an array of 10 cars, randomly assigning values to xpos,ypos. Using a pointer of type car in a for loop, display the state of all the cars. #include using namespace std;
int main() { system("color f0"); int xpos=10,ypos=20; int *car[10];
car[0] = &xpos; car[1] = &ypos; car[2] = &xpos; car[3] = &xpos; car[4] = &ypos; car[5] = &xpos; car[6] = &xpos; car[7] = &ypos; car[8] = &xpos; car[9] = &xpos; for(int a=0;a<10;a++) { cout << *car[a]<<", "; } }
