Problem # 1:

Writing a program that accepts a character and determines whether the character is a lowercase letter. A lowercase letter is any character that is greater than equal to 'a' and less than or equal to 'z'. If the entered character is a lowercase letter, display the message "Entered character is a lowercase letter", otherwise display the message "Entered character is not a lowercase letter".

Solution:

#include<iostream>
#include<conio.h>
using namespace std;
int main ()
{
    char c;
    cout<<"enter a character:";
    cin>>c;
    if(c>='a'&&c<='z')
    cout<<"\nEntered character is a lower case letter";
    else
    cout<<"\nEntered character is not a lower case letter";
    return 0;
}
