Write a C program with out using semicolon

The logic for this is tricky. Generally C language parse the code as expressions. Compiler checks for the valid expressions. If the expression is invalid , it will throw compilation error. It applies for the condition checking also. here comes the trick. see below example.

int main()

In the above code, it checks for the valid expression in if statement. It will check for the validity of the expresion and not the result/return value of the expression. So it will display the message. you can give any valid expression for condition check.

Result of the above code:

practice 1813> gcc nosemicolon.c
practice 1814> ./a.out
practice 1815>
