Increasing decreasing sequence

#1

Sir how do i break a sequence of nos without storing it
i have just input a sequence with the code:
#include
using namespace std;
int main()
{
int n,no;
cin>>n;
while(n>0)
{
cin>>no;
n=n-1;

}
return 0;

}

Hi @Megha2468
For that you have to include a if condition in you while loop and in if condition add break; statement which will move you out of the while loop.

sir how to compare two nos when I am not storing them

@Megha2468
In your code if you are using only n as variable then you need to compare it with an integer value like 0 or 1.
For example if you want to take input until you encounter 0 as input then you can use :
if(n==0){
break;
}

sir I am not having problem in taking input but in the sequence I need to compare nos like i have input 2
3
4
5
how do I go back and compare 2 and 3
3 and 4 as i have not stored them

@Megha2468
You can compare 3 variables at a time by taking a var x in while loop as :
while(n>0){
int x=n; // storing previous value of n
cin>>n; // taking input of new n
compare(x,n); // comparing previous and current value of n
x=n; // storing current value of n in x
cin>>n; // taking new input
compare(x,n); // comparing current and next value of n
}

Similarly you can compare as many as input in a single go but have to store them in a variable.
