Question

Please work on the following short programming assignments and upload your solutions on a single .txt file. 1. Write a function to take two integers and return the maximum number. Then, in the main function, ask the user to enter 2 numbers and output the maximum using the function. 2. Write a program to input 5 integers and store them in an array. Then, show the array in the output. 3. Write a program to input 5 numbers and store them in an array. Then, show the array value using pointers. 4. Write a program to input 9 numbers and store them in a 3*3 two-dimensional array. Then show the array in the output.

In C++

Answer 1

Q1.

Code :

#include <iostream>
using namespace std;

int maximum(int x1, int x2){ //function that return maximum number from two number
   if(x1>x2)
       return x1;
   else
       return x2;
}
int main(){
   int x1,x2;
   cout<< "Enter two number:\n";
   cin >> x1 >> x2; //taking two number from user
   cout << "Maximum number is " << maximum(x1,x2) <<endl; //printing maximum number using help of maximum() function
   return 1;
}

Q2.

Code :

#include <iostream>
using namespace std;
int main()
{
   int arr[5], i;
   cout << "Enter five number :\n";

   //taking five number from user and storing into array
   for( i=0; i<5; i++){
   cin >> arr[i];
   }

   //printing elements of array

   cout << "Array:\n";
   for( i=0; i<5; i++){
   cout << arr[i] << " ";
   }
   cout <<endl;

   return 0;

Q3

Code :

#include <iostream>
using namespace std;
int main()
{
   int arr[5], i;
   cout << "Enter five number :\n";

   //taking five number from user and storing into array
   for( i=0; i<5; i++){
   cin >> arr[i];
   }

   int *p = &arr[0]; //pointer

   //printing elements of array using pointer

   cout << "Array:\n";
   for( i=0; i<5; i++){
   cout << *p << " ";
   p++;
   }
   cout <<endl;

   return 0;

Q4.

Code :

#include <iostream>
using namespace std;
int main()
{
   int arr[3][3], i, j;
   cout << "Enter nine number :\n";

   //taking five number from user and storing into array
   for( i=0; i<3; i++){
      
       for(j=0; j<3; j++){
      
           cin >> arr[i][j];
      
      
       }
   }

   //printing elements of array

   cout << "\nArray:\n";
   for( i=0; i<3; i++){
      
       for(j=0; j<3; j++){
      
           cout << arr[i][j] <<"\t";
      
       }

       cout << endl;

   }
