Step 1

Decision logic structure:

  • This is generally, used by the programmers to chose that which valid set of instruction to be executed.
  • All the decision logic structures generally produce results in the boolean i.e., either true or false.
  • Generally, decision logic structures use the if/ else statements. here, if the given condition is true then if the block is executed, otherwise the else block is executed.
  • Consider the below given example:

 

//including required header files

#include <iostream>

using namespace std;

//main method

int main()

{

    //declaring required variables

    int x=2;

    //if the value of x is equal to 2

    if(x=2)

    {

        //displaying message to the user

    cout<<"x is equal to 2";

    }

    //otherwise

    else

    {

        //displaying message to the user

        cout<<"x is not equal to 2";

    }

    return 0;

}
