Relevant readings from text: K&R; Chapters 2 and 3. Write a program that prints the string "Hello, world! " to standard output. Note: You must name your file hello.c. Write a program that takes a character from standard input and then outputs one of three messages depending on whether the input is an uppercase letter, a lowercase letter, or any other character. At the start of the program, prompt the user to input a character by printing the string "Input one character: ". If the input is a lowercase letter, then print the string "You typed lowercase ", where is replaced with the character that was input by the user; if the input is an uppercase letter, then print the string "You typed uppercase "; otherwise, print the string "You did not type a letter. ". Example input/output pairs are provided below: Input: c; Output: You typed lowercase c. Input: R; Output: You typed uppercase R. Input: 6; Output: You did not type a letter. Input: $; Output: You did not type a letter.Explanation / Answer
// Hello World
#include<stdio.h>
#include<conio.h>
int main()
{
printf("Hello World");
_getch();
return 0;
}
// Case of Character
#include<stdio.h>
#include<string.h>
#include<conio.h>
int main() {
int upper = 0, lower = 0;
char ch;
int i;
printf(" Enter The Caracter: ");
scanf("%c",&ch);
if (ch >= 'A' && ch <= 'Z')
upper++;
if (ch >= 'a' && ch <= 'z')
lower++;
if (upper == 1)
printf(" You typed Uppercase : %c", ch);
else if (lower == 1)
printf(" You typed Lowercase : %c", ch);
else
printf(" You didn't type a letter ");
getch();
return (0);
