Question

I do not know where to begin with this code

Using C++ code, write a program to print "R" if 2 random integers A and b in the range [-80,  

80] are both positive, "L" if A and B are both negative and "Z" otherwise.

Answer 1

The Program is given below with proper comments, also see the screen shots for code and sample results for more clarity:

Code

 #include<iostream> #include <cstdlib> using namespace std; int main() { //Declare integers int a,b; //Input any two integers in the range [-80,80] cout<<"Enter value for a: "; cin>>a; cout<<"\nEnter value for b: "; cin>>b; //check whether the input belongs to the required range [-80,80] while(abs(a)>80 || abs(b)>80) { //Display errors cout<<"Invalid inputs enter any two numbers in the range [-80,80]"<<endl; //Input any two integers in the range [-80,80] cout<<"Enter value for a: "; cin>>a; cout<<"\nEnter value for b: "; cin>>b; } //print "R" if a and b are positive if(a>0 && b>0) { cout<<"R"<<endl; } //print "L" if a and b are negative else if(a<0 && b<0) { cout<<"L"<<endl; } //Otherwise print "Z" else { cout<<"Z"<<endl; } return 0; }
