The
"if ... else" Statements
 |
Let's look
at situations when the word "otherwise" can be
used in your decision making! |
|
if (test
condition)
{
block of one;
or more C++ statements;
}
else
{
block of one;
or more C++ statements;
} |
If the test condition is TRUE, the
block of statements following the "if" executes. If the test
condition is FALSE, however, the block of statements following the
"else" executes instead.
Example:
//example of if ... else
cout<<"Enter the name of your city."
getline (cin, city);
cout<<"Enter the population";
cin>>population;
if (population >= 534187)
{
cout<<"According to the census,
" << city
<<" is one of \n the 100 largest cities."
}
else
{
cout<<"According to the census,
" << city
<<"is not one of \n the 100 largest cities."
}
