Does it need a ";" at the very after of "if" and "for"

[marsarden]

write code like:

int main(void)
{
int a=10;
if(a<20)
{}
}

Compiler ok on dev-cpp . don't we have to add a ";" after if
statement?

The syntax for 'if' is:

if(expression) statement

There is no semicolon after the ) but before the statement.

The statement is either a normal statement (which can be empty), ending in a
semicolon:-

if(expr)
foo();

if(expr)
;

or a list of zero or more statements enclosed in braces:

if(expr)
{
foo();
bar();
}

if(expr)
{
}
