C :

#include<stdio.h>
int main()
{
    int x,a,b,c,d,max=0;
    scanf("%d%d%d%d%d",&x,&a,&b,&c,&d);
    if(x>max)
        max=x;
if(a>max)
    max=a;
    if(b>max)
        max=b;
    if(c>max)
        max=c;
    if(d>max)
        max=d;
    printf("%d",max);
    return 0;
}

C++ :

#include <bits/stdc++.h>;
using namespace std;
int main(){
	int a[5]={0};
	int s,b,c,d,e;
	cin>>s>>b>>c>>d>>e;
	a[0]=s;
	a[1]=b;
	a[2]=c;
	a[3]=d;
	a[4]=e;
	sort(a,a+5);
	cout<<a[4]<<endl;
}

Java :

import java.util.Scanner;
public class Main
{   
	public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        int a = sc.nextInt();
        int b = sc.nextInt();
        int c = sc.nextInt();
        int d = sc.nextInt();
        int e = sc.nextInt();
        int max = a;
        if(max<b) {
        	max=b;
        }
        if(max<c) {
        	max=c;
        }
        if(max<d) {
        	max=d;
        }
        if(max<e) {
        	max=e;
        }
        System.out.println(max);
    }
}

Python :

n = input().split()
a = int(n[0])
b = int(n[1])
c = int(n[2])
d = int(n[3])
e = int(n[4])
ma = max(a, b, c, d, e)
print(ma)
