Introduction

C++ program to print day name of week. I have used DEV-C++ compiler for debugging purpose. But you can use any C programming language compiler as per your availability.

#include<iostream>
using namespace std;

int main()
{
    int week;

    cout<<"Enter week number (1-7):";
    cin >> week;

    if(week == 1)
    {
        cout << "Monday";
    }
    else if(week == 2)
    {
        cout << "Tuesday";
    }
    else if(week == 3)
    {
        cout << "Wednesday";
    }
    else if(week == 4)
    {
        cout << "Thursday";
    }
    else if(week == 5)
    {
        cout << "Friday";
    }
    else if(week == 6)
    {
        cout << "Saturday";
    }
    else if(week == 7)
    {
        cout << "Sunday";
    }
    else
    {
        cout << "Invalid Input! Please enter week in between 1-7.";
    }
    return 0;
}
