if-else (nested support)
While loop (nested support)
For loop (nested support)
break statement

if-else syntax:

	e.g.
	condition should be only of this form: a<b

	if(a<b){
	t = t+1
	}else{
	j = j+1
	}

while loop syntax:
	
	e.g
	while(a<b){
	a=a+1
	}

for loop syntax:

	e.g
	for(i=0;i<j;i=i+1){   
	k = k+1
	}

Break statement syntax:
	
	e.g
	if(a<b)break

e.g
./a.out<strln.prog
