Answer:
Following are the program to this question:
#include <iostream>//defining header file
using namespace std;
void OR_gate()//defining a method OR_gate
{
bool a,b;//defining bool vaiable
cin>>a>>b;//input value
if(a or b)//use if block to check condition
{
cout<<"1";//print message
}
}
int main()//defining main method
{
OR_gate();//calling method OR_gate  
return 0;
}
Output:
0
1
1
Explanation:
In the above program, a method "OR_gate" is declared, and inside the method two bool variable "a and b" is defined, which input the value from the user end.
In the next step, an if block is defined, that uses the or gate to check input value and print the value that is equal to 1, and inside the main method, it call the "OR_gate" method. 
 
        
             
        
        
        
A crime problem in my community is related to cell phone theft. According to the local newspaper, it is estimated that in my city about 10 cell phones are stolen per week. Still according to the local newspaper, most of these robberies occur in the city center and in the periphery, with women being the biggest victims.
Although the police have shown themselves to be a restraining force on this type of crime, few arrests have been made successfully, mainly for the negligence of the victims in providing a complaints.
The main driving force behind this crime is drug trafficking. Most burglars steal cell phones to sell them and have money to buy drugs. This is totally related to the government's neglect to promote quality education in the city, allowing several children and young people to stay on the street and run the risk of becoming involved in the traffic.
A cause and effect diagram for this situation is:
Irresponsible government ---> poor quality education ---> children and adolescents on the streets ---> involvement in drug trafficking ---> theft of cell phones ----> frightened population --->  lack of complaints ----> criminals on the street.
