C++ Vowels, AscII, Pascal triangle, Vice versa pro

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

#include 

#include 

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();

}

Output

Uppercase Consonants = 5.

Lowercase Consonants = 13.

Uppercase Vowels = 3.

Lowercase Vowels = 7.

Number of vowels = 10

Program to convert temperatures from Celsius to Fahrenheit and vice versa

#include 

#include 

void main()

{

clrscr();

int choice;

float ctemp,ftemp;

cout << "1.Celsius to Fahrenheit" << endl;

cout << "2.Fahrenheit to Celsius" << endl;

cout << "Choose between 1 & 2 : " << endl;

cin>>choice;

if (choice==1)

{

cout << "Enter the temperature in Celsius : " << endl;

cin>>ctemp;

ftemp=(1.8*ctemp)+32;

cout << "Temperature in Fahrenheit = " << ftemp << endl;

}

else

{

cout << "Enter the temperature in Fahrenheit : " << endl;

cin>>ftemp;

ctemp=(ftemp-32)/1.8;

cout << "Temperature in Celsius = " << ctemp << endl;

}

getch();

}

Output

          Temperature in Celcius = 37

Program to print the first 10 lines of pascal's triangle

#include 

#include 

#include 

long triangle(int x,int y);

int main()

{

clrscr();

const lines=10;

for (int i=0;i

for (int j=1;j

cout << setw(2) << " ";

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

cout << setw(4) << triangle(i,j);

cout << endl;

getch();

}

long triangle(int x,int y)

{

if(x<0 y="">x)

return 0;

long c=1;

for (int i=1;i<=y;i++,x--)

c=c*x/i;

return c;

}

Output

       1  10  45  120  210  252  210  120  45  10  1
