C :

#include<stdio.h>
main() 
{
	int i,n,t=0,m=0;
	scanf("%d",&n);
	int a[n];
	for(i=0; i<n; i++) 
	{
		scanf("%d",&a[i]);
	}
	for(i=0; i<n; i++) 
	{
		t++;
		if(a[i]>a[i+1]||i==n-1) 
		{
			if(t>m) 
			{
				m=t;
			}
			t=0;
		}

	}
	printf("%d",m);
}

C++ :

#include <iostream>
using namespace std;
int a[10000010],n,i,ma = 0,c = 0;
int main(){
	cin>>n;
	for(i = 0;i < n;i++){
		cin>>a[i];
	}
	
	for(i = 0;i < n;i++){
		c++;
		if(i == n - 1 || a[i] >= a[i + 1]){
			if(c > ma) ma = c;
			c = 0;
		}
	}
	
	cout<<ma<<endl;
}

Java :

import java.util.Scanner;

public class Main {
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int n = sc.nextInt();
		int[] a = new int[n];

          getSum(a);
	}
	public static void getSum(int[] a){
		int count = 1;int s = 0;
		for(int i = 0;i<a.length-1;i++){

Python :

for i in range(n):

for i in range(1,n):
    if(a[i]>a[i-1]):
        js=js+1
    else:
        if(js>da):
            da=js
        js=1
if(js>da):
    da=js
print(da)
