Introduction
C program to check uppercase or lowercase alphabets. I have used DEV-C++ compiler for debugging purpose. But you can use any C programming language compiler as per your availability.
C program to check uppercase or lowercase alphabets
#include <stdio.h>
int main()
{
char ch;
printf("Enter any character: ");
scanf("%c", &ch);
if(ch >= 'a' && ch <= 'z')
{
printf("%c is lowercase alphabet.", ch);
}
else if(ch >= 'A' && ch <= 'Z')
{
printf("%c is uppercase alphabet.", ch);
}
else
{
printf("%c is not an alphabet.", ch);
}
return 0;
}Result
