Question

Write a program to convert the alphabets of lower class to upper class and vice versa.

Answer 1

# include<iostream>

using namespace std;

int main()

{

char a[30];

cout << "Enter a string";

cin >> a;

for(int i = 0; a[i]!='\0';i++)

{

if(a[i] >= 97 && a[i] <= 132)

a[i]=a[i] - 32;

else

a[i] = a[i] + 32;

}

cout << "Uppercase is: "<<a;

}

Output:

Enter a string : Siddhartha

Uppercase is : SIDDHARTHA.

Hope it helps!

Answer 2

Note: By a ASCII character, here, "a" has the output Html of 97 and between those characters by a starting extractor operation it's going to be, "a" - "A" = 32, for an exact encoding.

#include<iostream>

#include<conio.h>

using namespace std;

int main()

{

clrscr();

char ch;

cout << "Submit any Alphabet you like";

cin >> ch;

if(ch>='a' && ch<='z')

{

cout << "You have submitted a lower case alphabet. ";

ch = ch-32;

cout << "The Upper case alphabet, here, will be: "<<ch;

}

else

{

cout << "You have submitted a Upper case alphabet. ";

ch = ch+32;

cout << "The lower case alphabet, here, will be: "<<ch;

}

getch();

}


$\textbf{FINAL OUTPUT :}$



By submitting a upper case alphabet: Vishwas


The lower case alphabet for first letter is going to be: vishwas
