Single Character Output‒putchar() function - Basic C Programs

C Program - Convert a Character from Lowercase to Uppercase and viceversa.

/* Program to convert a character from Lowercase to Uppercase */

#include <stdio.h>

main()

{

char ch; /* Local definition */

printf("Enter any alphabet either in Lower or Uppercase......");

ch=getchar();

if(islower(ch))

putchar(toupper(ch)); /* tape converts the character to upper case */

else

putchar(tolower(ch)); /* tolower() converts the character to lower case */

} /* main */

OUTPUT:

1. Enter any alphabet either in Lower or Uppercase........s

2. Enter any alphabet either in Lower or Uppercase........M

EXPLANATION: In this program the getchar() function reads the single character from the terminal. The program finds whether the character is lower or upper case if the character is lower case then it is converts to uppercase using toupper() function, else if the character is uppercase then it is changed to lowercase using tolower() function and produced the output.
