Accept String Lower Case

Write a program to accept a string or name from the user and convert it in lower case.

Read a string from user using gets(). Now travel the whole string and check it is an alphabet or Not. If it is an alphabet then check is it a upper case character [ASCII between 65 - 90], if it is a upper case character then add 32 with it and convert into lower case character. Now print the string using puts().

int main()
{
	char str[30],i;
	//READ A STRING
	printf("Enter A String: ");
	gets(str);
	for(i=0;str[i]!='\0';i++)
	{
		if((str[i]>=65 && str[i]<=90) ||(str[i]>=97 && str[i]<=122))
		{
			if(str[i]>=65 && str[i]<=90)
			{
				str[i]=str[i]+32;
			}
		}
	}
	//PRINT THE OUTPUT
	printf("Result : ");
	puts(str);
	return 0;
}
