An if
statement is used to test an expression for truth and execute some code based on it. Here’s a simple form of the if
statement:
if (condition) { // Statement(s) }
If the condition is true
, then the statements within the if
block are executed. These statements are any lines of code that would otherwise be normally executed by the program. When the condition is false
, the inside statements are skipped and the program continues on.
if (flip == 1) { printf("Heads\n"); }
The if
keyword is followed by a set of parentheses ()
. Inside these parentheses, a condition is provided that evaluates to true
or false
:
- If the condition evaluates to
true
, the code inside the curly braces{}
executes. - If the condition evaluates to
false
, the code doesn’t execute.
So in the code above, if flip
is equal to 1, the program outputs “Heads”; if it does not, then nothing happens and the program continues.
