Sample C Program to accept a string in upper case and print it in lower case.

28) Sample C Program to accept a string and print it by using the while loop.

# include <stdio.h>
# include <conio.h>
main( )
{
char ch;
clrscr();
printf("Enter a string:");
while(( ch = getchar() ) != '\n')
   putchar(ch);
getch();
}


29) Sample C Program to accept a string in upper case and print it in lower case.

# include <stdio.h>
# include <conio.h>
main( )
{
char ch,c;
clrscr();
printf("Enter a string in upper case:");

while(( ch = getchar( ) ) != '\n')
  {
     c = ch + 32;
     putchar(c);
  }

printf(" :String In Lower Case");
getch( );
}


30) Sample C Program to accept a string in any case and print it by another case.

# include <stdio.h>
# include <conio.h>
main( )
{
char ch;
clrscr( );
printf("Enter a string:");
 while(( ch = getchar( )) != '\n')
{
if(ch >= 'A' && ch <= 'Z')
putchar(ch + 32);
else
if(ch >= 'a' && ch <= 'z')
putchar(ch - 32);
else
putchar(ch);
}
printf(" :is the converted string.");
getch( );
}
