Question

Is the decision logic involved in problem-solving?

Expert Solution

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;

}
