Yes, but 'cout' is not a statement! Examples for statements: null-statement, block, expression, if-else, while, do-while, for, continue, switch, break, return.
Only the true path in the If...Then...Else statement
Yes int main (void) { puts ("if statement"); puts ("else statement"); return 0; }
if(condition) { statements /* ... */ }
There is no "elseif" statement in C. You can only use "else" and "if" separately. This is a good reason for switch/case/break.
if-then-else
A threat is an "or else" statement Here are some examples: You better listen to me or else... You better not mess with me or else... You better do well on your test or else.... You better do what I say or else... Do it now or else...

if () orif () else examples:if (argc==1); /* null-statement */else if (argc==2)if (strcmp (argv[1], "help") /* nested if */{ puts ("Help"); } /* compound statement */else puts ("No help");else printf ("argc=%d\n", argc);
An if-then statement, or simply an if statement, checks if a stated condition is true. If the condition is true, then a block of code will then execute. Example: if number equals 3 print out "Number equals 3" An if-then-else statement, or simply an if-else statement, checks if a stated condition is true. If the condition is true, then a certain block of code will then execute. If the condition is false, then a different block of code will then execute. Example: if number equals 3 print out "Number equals 3" else print out "Number does not equal 3" For both if statements and if-else statements, there is only one stated condition. The difference between them is that an if statement will only cause something to happen if the condition is true. An if-else statement will execute a block of code whether the condition is true or false.
If(condition) { if-else statement; } else { if-else statement; }

Yes int main (void) { puts ("if statement"); puts ("else statement"); return 0; }
The standard syntax is:if( conditional_expression )statement;[[else if( conditional_expression )statement;[else if...]]else statement;][] denotes optional components. Each statement may be a single statement, or may be multiple statements surrounded by braces {}.The if( conditional expression ) statement; is the only required component. In plain English, this reads: if the conditional expression is true, then execute the following statement, otherwise skip to the line following the statement.If the next line is an else statement, then the line reads: if the conditional expression is true, then execute the statement and skip over the else statement. But if the conditional expression is false, then skip over the statement and execute the else statement instead.if( conditional_expression )statement; // execute when conditional expression is trueelsestatement; // execute when conditional expression is falseThe statement following the else can be another ifstatement (a nested if):if( conditional_expression_1 )statement; // execute when conditional_expression_1 is true.else if( conditional_expression_2)statement; // execute when conditional_expression_1 is false and _2 is true.elsestatement; // execute when both _1 and _2 are both false.Note that if an else statement is used without a following if statement, it must appear after all other else if statements.
Statements. Typical usage: if (<condition>) <statement>; else <statement>;
