Write a program which has a function named lower which converts an upper case character value into its corresponding lower case character. The function does not return anything.

#include <stdio.h>

void lower(char *);

int main(void)
{
char ch;

printf("\nEnter a character : ");
scanf("%c", &ch);

lower(&ch);

printf("\nConverted character = %c", ch);

return 0;
}

void lower(char *cp)
{
if(*cp >= 'A' && *cp <= 'Z')
*cp = *cp + 32;
}
