TRY IT: Using Relational and Logical Operators C++

LAB 4. 1 TRY IT: Using Relational and Logical Operators

Step 1: Add the tryIt4A.cpp program in your Lab4 folder to the project. Below is a copy of the source code lines that contain output statements. Remember that arithmetic operations are done before relational operations and that relational operations are done before logical operations. Recall also that if you output a Boolean variable or the result of a Boolean expression, true displays as a 1 and false displays as a 0.

1 // Lab 4 tryIt4A 10 cout << ( 3 == 4) << endl; 11 cout << ( 3 == 3) << endl; 12 cout << ( 5 == 3 + 2) << endl << endl; 14 cout << (7 > 5) << endl; 15 cout << (7 > 5 + 2) << endl; 16 cout << (2 >= 8 % 3) << endl << endl; 18 cout << (8 < 6) << endl; 19 cout << (3 * 5 < 2 * 9 - 1) << endl; 20 cout << (5 * 4 <= 40 / 2) << endl << endl; 22 cout << (3 != 5) << endl; 23 cout << (3 != 9 - 2 * 3) << endl; 24 cout << (10 != (4 * 5) / 2) << endl << endl; 26 cout << (5 > 6 && 3 < 4) << endl; 27 cout << (5 > 6 || 3 < 4) << endl; 28 cout << (!(7 > 6)) << endl << endl; 30 cout << ( 2 * 3 == 6 && !(1 > 2) ) << endl; 31 cout << ( !(2 * 3 == 6 && 1 > 2) ) << endl; 32 cout << ( !(2 * 3 == 6 && 1 != 2) ) << endl;

Expected Output ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________

Observed Output ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________ ____________

Step 2: Read the source code, paying special attention to the relational and logical operators. Then complete the Expected Output column, writing down the output you think each cout statement will produce.

Step 3: Now compile and run the tryIt4A.cpp program, and look at the output it creates. If the actual output from a cout statement matches what you wrote down, just place a checkmark in the Observed Output column. If it is not the same, write down the actual output.
