Program to enter a sentence and output the number of uppercase & lowercase consonants, uppercase & lowercase vowels in sentence..

#include <iostream.h>
#include <conio.h>

void main()
{
clrscr();
char line[80];
int number_of_vowels,uc,lc,uv,lv;
uc=lc=uv=lv=0;
cout << "Enter your sentence : " << endl;
cin.getline(line,80);
for(int x=0; line[x]!='\0';x++)
{
if(line[x]=='A'||line[x]=='E'||line[x]=='I'||line[x]=='O'||line[x]=='U')
uv++;
else if(line[x]=='a'||line[x]=='e'||line[x]=='i'||line[x]=='o'||line[x]=='u')
lv++;
else if(line[x]>+65&&line[x]<=90)
uc++;
else if (line[x]>=97&&line[x]<=122)
lc++;
}
//Printing the output.
cout << "Uppercase Consonants = " << uc << "." << endl;
cout << "Lowercase Consonants = " << lc << "." << endl;
cout << "Uppercase Vowels = " << uv << "." << endl;
cout << "Lowercase Vowels = " << lv << "." << endl;
number_of_vowels=uv+lv;
cout << "Number of vowels = " << number_of_vowels << endl;
getch();
}

This program takes in a sentence as a screen input from the user.
It then computes the number of uppercase and lowercase consonants, uppercase and lowercase vowels and the total number of vowels.
It then outputs it using the 'cout' command.
