C++ = Arrays multiplication and printing on screen

Create a matrix of order 4x3 in program that prompt user his roll no: then multiply 2023 with that created matrix then print it on the screen. 

CODE:

#include <iostream>

using namespace std;

int main()

{

    int a[4][3],b[4][3];

    

    cout<<"Enter single digit of your roll number : ";

    

    for (int i=0;i<4;i++)

    {

    for (int j=0;j<3;j++)

    {

    cin>>a[i][j];

}

}

for (int i=0;i<4;i++)

{

for (int j=0;j<3;j++)

{

b[i][j]=a[i][j]*2023;

}

}

cout<<"The matrix of 4x3 after multiplication with 2023 is "<<endl;

for (int i=0;i<4;i++)

{

for (int j=0;j<3;j++)

{

cout<<b[i][j]<<"      ";

}

  cout<<endl; 

}

return 0;

}


RESULT:

C++ = Code for checking any digit palindrome number

Code no: 1 = Using only main function to perform task. #include <iostream> using namespace std; int main() { int number,original,digit,reverse=0; cout<<"Enter any number : "; cin>>number; original=number; while (number!=0) { digit=number%10; reverse=(reverse*10)+digit; number=number/10; } if (original==reverse) { cout<<"This "<<original<<" is Palindrome number."; } else { cout<<"The "<<original<<" is not Palindrome number."; } } Result: Code no: 2 = Using two functions to perform same task. #include <iostream> using namespace std; int isprime(int num) { int digit=0,reverse=0; while (num!=0) { digit=num%10; reverse=(reverse*10)+digit;  num/=10; } return reverse; } int main() { int num; cout<<"Enter any digit to find its sum = "; cin>>num;          int original=num;          if (i...
