Algorithm analysis

Use the function toupper, which converts characters to uppercase.

Algorithm realization

Declare a char array.

char s[101];

Read the input string.

gets(s);

Convert all characters in the string to uppercase.

for (i = 0; i < strlen(s); i++)

s[i] = toupper(s[i]);

Print the answer.

puts(s);

Algorithm realization – C++

Read the input string.

getline(cin, s);

Convert all characters in the string to uppercase.

for (int i = 0; i < s.size(); i++)

s[i] = toupper(s[i]);

Print the answer.

cout << s << endl;

Java realization

import java.util.*;

public class Main

{

public static void main(String[] args)

{

Scanner con = new Scanner(System.in);

String s = con.nextLine();

s = s.toUpperCase();

System.out.println(s);

con.close();

}

}

Python realization
