b=a+3;

c=20;

}

else

{

cout << "angouraki" << endl;

}

The statement

cout << "angouraki" << endl;

prints the word “angouraki” on the screen and moves the cursor to the

next line.

• if/else if structure:

Theif/else ifstructure implements conditional execution based on

several options.

For example, we may write:

if(a==1)

{

b=a+3;

c=20;

}

else if (a==2.3)

{

cout<<"angouraki"<<endl;

}

else

{

cout<<"maintanos"<<endl;

}

We can use multipleelse ifblocks and skip the lastelseblock. If

two options coincide, the first-encountered option will be executed before

exiting the structure.

Note thatelseandifare two separate words separated by white space.

InMatlab, these two words are merged into the ungrammaticalelseif.

• switch structure:

Consider an integer or character variable,diosmos.Ifdiosmos=n 1
