what if i want to write another function : 
int main(){

	const int length = 30;
	const int width = 20;
	const char newline = '\n';

	int area;

	area = length * width;

	if( length < width){
	printf("the size of this property : %d", area);
	printf("%c", newline);

	} else if(length > width){
		for(int n = 0; n<2; n++){
			printf("miao\n");
		}
	} else{
		for(int i =0; i < 3; i++){
			printf("haooo\n");
		}
	}
	return 0;
}

i tried to write another function after it that isn't called main and it didn't run it, why so?
