If else Statement in C++

The if_else statement is a powerful decision making tool. It allows the computer to evaluate the expression. Depending on whether the value of expression is 'True' or 'False' certain group of statements are executed.

The syntax of if_else statement is:

if (condition is true)

    statement 1;

else

    statement 2;

The condition following the keyword is always enclosed in parenthesis. If the condition is true, statements in then part are executed, i.e., statement1, otherwise statement2 in else part is executed. There may be a number of statements in then and else parts.

Example:

/* magic number program * /

main( )

{

    int magic = 223;

    int guess;

    cout<<"Enter your guess for the number \n";

    cin >>guess;

    if (guess = = magic)

                cout<<"\n Congratulation ! Right guess";

    else

                cout<< "\n wrong guess";

}
